Acid mine drainage and metal-rich mine water treatment with passive biological systems — sulfate-reducing bioreactors, compost wetlands, aerobic wetlands — instead of perpetual lime dosing

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: perpetual lime dosing or no treatment · Scope: mine water · Evidence: high

The chemical problem#

Acid mine drainage (AMD) forms when sulfide minerals oxidize in mine workings and waste dumps, and it continues for centuries after mining ends. The Karabash copper-smelting and mining area in the Urals is often cited among the most polluted places in Russia, with acidic, metal-laden streams. Conventional treatment with lime requires continuous chemicals, energy and staff, and produces large volumes of metal sludge to landfill.

Agricultural spraying drones instead of knapsack and manned aerial spraying

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: knapsack and manned aerial spraying · Scope: plant protection application · Evidence: high (method), weak (chemical saving)

The old process#

In smallholder Asia, pesticides were sprayed by hand with knapsack sprayers — slow, labour-intensive and with high operator exposure; in wet rice fields tractors cannot enter.
Elsewhere, manned aircraft sprayed large areas with significant drift.

Product overview#

Plant-protection drones (UASS) fly autonomously over a mapped field and spray at low volume with rotor downwash pushing droplets into the canopy. Chinese makers (DJI Agriculture, XAG) dominate. In China drone spraying became a mass service industry within a decade; Japan used unmanned helicopters for rice since the 1990s.

Apple and pear storage without diphenylamine (DPA) and post-harvest fungicide drenches — dynamic controlled atmosphere (DCA), hot-water dipping, pre-harvest biocontrol and orchard sanitation

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: diphenylamine and post-harvest fungicide drenches · Products: apples, pears · Evidence: high

The chemical problem#

Superficial scald (a browning of apple skin during long storage) was prevented for decades with diphenylamine (DPA) drenches. The EU did not approve DPA (2012), partly because of the potential formation of nitrosamines, and the MRL was set at 0.1 mg/kg. Post-harvest fungicide drenches (thiabendazole and others) leave residues on ready-to-eat fruit, and the recirculated drench liquid spreads Penicillium spores and resistance.

Augmentative biological control in greenhouse vegetables instead of insecticide and acaricide programmes

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: insecticide and acaricide spray programmes · Scope: greenhouse vegetables · Evidence: high

The chemical problem#

Greenhouse vegetables face whitefly, thrips, aphids, spider mites and leafminers year-round; the old answer was frequent sprays of broad-spectrum insecticides and acaricides.
Pests became resistant, residues triggered market rejections, and workers were exposed in enclosed spaces. In December 2007 the illegal pesticide isofenphos-methyl was found in Almería peppers, threatening exports.

Product overview#

Augmentative biological control: commercially reared natural enemies are released preventively and as needed, supported by monitoring (sticky traps), selective microbial products (Bacillus, Beauveria) and pollination by bumblebees (CE04), which itself requires a low-pesticide environment. The Netherlands built this system from the 1970s; Almería (Spain) switched almost overnight after 2007.

Bacteriophage therapy for bacterial disease in fish and shrimp farming instead of medicated-feed antibiotics

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: medicated-feed antibiotics for bacterial disease · Species: fish and shrimp · Evidence: medium

The chemical problem#

Bacterial disease is the main reason antibiotics enter aquaculture. Furunculosis and enteric redmouth (Aeromonas salmonicida, Yersinia ruckeri), vibriosis (Vibrio anguillarum, V. harveyi), motile Aeromonas septicaemia in tilapia and catfish, Edwardsiella infections - these are treated by mixing oxytetracycline, florfenicol or quinolones into feed for whole ponds, or by bath treatments. A large share of the dose never reaches the fish: it dissolves into water and sediment, where resistance genes can move into environmental and human pathogens. Quinolones and third-generation cephalosporins used in fish farming overlap with critically important human antibiotics, and importing markets increasingly test for residues.

Baking enzymes (fungal amylase, maltogenic amylase, xylanase, glucose oxidase, lipase) plus ascorbic acid instead of potassium bromate and azodicarbonamide as flour treatment agents

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: potassium bromate, azodicarbonamide · Scope: bread and bakery, flour mills, improver blenders · Evidence: high

The chemical problem#

Potassium bromate strengthens dough and raises loaf volume, but is a kidney carcinogen in rats (IARC Group 2B). Residues can remain in bread if baking is incomplete.
Azodicarbonamide (ADA) bleaches and oxidizes flour; in baking it forms semicarbazide, and workers handling it can develop asthma.
Status: bromate is banned in the EU, UK, Canada, China, India (FSSAI, 2016), Brazil and others; ADA is not authorized as a flour treatment agent in the EU. California has banned bromate in food from 2027. Both remain legal and in use in many other markets.

Product overview#

Modern “clean-label” bread improvers combine:

Bio-based and safer solvents — Cyrene (dihydrolevoglucosenone from cellulose), 2-methyltetrahydrofuran (2-MeTHF from furfural/levulinic acid), ethyl lactate, bio-ethanol, γ-valerolactone, limonene — instead of NMP, DMF, DMAc, dichloromethane and other hazardous solvents

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: reprotoxic dipolar aprotic solvents and chlorinated solvents · Scope: chemical and manufacturing industries · Evidence: high for hazards

The chemical problem#

Solvents are often the largest mass of material in chemical processes, especially in pharmaceutical manufacture. NMP, DMF and DMAc are reproductive toxicants, and the EU restricted NMP (Regulation (EU) 2018/588) and DMF (2021/2030). Dichloromethane paint strippers have killed workers and consumers through acute exposure, and the EU and US restricted DCM for consumer paint stripping. Russia and the CIS still use these solvents widely.

Bio-based and soil-biodegradable plastics instead of fossil commodity plastics (PET, LDPE, PS) and their microplastics

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: fossil PE/PP/PS/PET packaging, intentional microplastics · Scope: drop-ins + biodegradables · Evidence: high for drop-ins

The chemical problem#

All fossil plastics are petrochemistry: about 8 Gt produced historically, nearly all still here as waste or microplastic (Geyer et al. 2017).
Intentional microplastics (scrub beads, glitter, capsule shells) are now restricted in the EU (REACH restriction, Regulation (EU) 2023/2055, from 2023).
“Oxo-degradable” films fragment into microplastics rather than biodegrading — banned in the EU since 2021 (see PK03).
The problem this article owns is carbon source + end-of-life: the first three PK articles addressed additives (PFAS, phthalates) and agricultural film; this one replaces the plastic itself.

Product overview#

Two complementary substitution routes:

Bio-based binders and bio-solvents instead of petrochemical resins and VOC solvent systems in paints and coatings

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: petro binders + VOC solvents · Scope: decorative, wood, some industrial coatings · Evidence: high for waterborne, medium for bio-monomers

The chemical problem#

Solvent-borne paints carry 30–60 % VOC solvent (white spirit, toluene, xylene): painter exposure, indoor off-gassing, ground-level ozone — the reason the EU capped paint VOC content in 2004 (Directive 2004/42/EC) and cities restrict decorative spraying.
The binder — the film itself — is petro: acrylic monomers, fossil alkyd oils, epoxy chains.
“Alkyd” is the historical irony: the class was always oil-modified; a century of cheap petro pushed the vegetable oil out.

Product overview#

Vegetable-oil and lignin-modified binders: soy/sunflower/castor alkyds (the return of the original recipe), lignin-based resins (paper-mill side stream → aromatic binder backbone), cellulose ethers as thickeners.
Waterborne reformulation: acrylic dispersions in water — the mainstream VOC exit (decades proven), increasingly with bio-based acrylate monomer fractions as those scale.
Bio-solvents for what still needs solvent: ester and terpene solvents, lactate esters (I01’s chains — same sugar feedstocks).
Performance segment: bio-epoxy (cardanol from cashew nutshell liquid), UV-cured plant-oil systems for wood flooring.

Active ingredient / Composition#

Alkyd: polyol + diacid + triglyceride oil fractions (30–70 % oil length); lignin phenolics replace part of the petro aromatic.
Waterborne: polymer dispersion 40–50 % in water + coalescing aid (moving to bio-based coalescents).
Bio-solvents: ethyl lactate, ethylate esters, D-limonene classes.

Key facts#

Parameter	Value
Class	Bio-based binders / waterborne systems
VOC law	EU 2004/42/EC phase II limits; national low-VOC labels
Bio-content claims	Verify by ASTM D6866 (14C) — “bio-based” ≠ “low-VOC” (separate axes)

| Durability | Bio-alkyds proven in wood protection; bio-acrylics reaching parity |

Advantages#

Cuts painter and occupant VOC exposure immediately; low-odor repaints.
Binder carbon swaps from fossil to crop/residue streams (lignin valorizes pulp mills — C02/I05 adjacency).
Waterborne tooling and skills already exist everywhere — reformulation, not retraining.

Mode of action#

Film formation unchanged: polymer chains coalesce/solvent-evaporate/oxidatively crosslink (alkyds: oil double bonds + O₂ — literally air-cured biochemistry).
The substitution is feedstock chemistry, not physics — the FPC lesson again.

Application#

Use	Target	Method, timing and specifics
Interior walls	VOC exit	Waterborne, low-VOC labeled; bio-coalescent grades
Wood windows/facades	Alkyd feel, water cleanup	Waterborne alkyd hybrids / vegetable-oil alkyds
Industrial wood (flooring, furniture)	Spec parity	UV-cured bio-acrylates, bio-epoxy cardanol systems
Maintenance paints	Solvent phase-out	High-solids + bio-solvent where waterborne can’t go

Limitations#

Bio-monomer supply is young; 100 % bio-acrylics are not yet commodity.
Drying-time and film-hardness trade-offs per system; spec testing per substrate.
“Natural” ≠ harmless: some terpene solvents sensitize (label discipline).
Industrial anti-corrosion and marine specs stay petro-dominated (see SKIPPED).

Evidence of displacement — D1: works, adoption not proven#

Assessment (hand-reviewed): Mismatch: UK paint VOC emissions fell ~60% under the Paints Directive — mainly water-borne paints, not bio-based binders.

Bio-based building insulation — wood-fibre boards, hemp and flax mats, cellulose, straw, hempcrete, mycelium panels — instead of polystyrene/polyurethane foams with brominated or chlorinated flame retardants and isocyanate spray foams

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: flame-retarded plastic foams and isocyanate spray foams · Scope: buildings · Evidence: high

The chemical problem#

Plastic foam insulation needs flame retardants. HBCDD was used for decades in polystyrene and is now a Stockholm Convention persistent organic pollutant (listed in 2013). Millions of tonnes of HBCDD-containing insulation remain in buildings and will become hazardous waste. PU/PIR foams contain TCPP. Spray PU foam exposes installers to isocyanates, the leading cause of occupational asthma.

Bio-based plasticizers — epoxidized soybean/linseed oil (ESBO), citrate esters (ATBC), isosorbide diesters, castor-oil derivatives — instead of ortho-phthalates (DEHP, DBP, BBP, DIBP) in PVC

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: reprotoxic ortho-phthalates · Scope: plastics · Evidence: high

The chemical problem#

Flexible PVC contains 20–50 % plasticizer, and the plasticizer is not chemically bound, so it leaches. DEHP and other low-molecular-weight phthalates are reproductive toxicants (anti-androgenic effects on male reproductive development) and are found in nearly everyone’s urine. The EU restricted DEHP, DBP, BBP and DIBP in most consumer articles (REACH Annex XVII, from 2020) and placed them on the Authorisation list. Medical devices must justify their use.

Biochar as a composting and manure additive, a feed additive and a low-cost sorbent for water and soil treatment — instead of coal-based activated carbon, chemical odour and ammonia binders, and part of clay toxin binders

Mon, 01 Jan 0001 00:00:00 +0000

Replaces (partial): coal-based activated carbon, chemical binders, some clay binders · Scope: compost, livestock, water · Evidence: medium–high (composting), medium (sorption), low–medium (feed)

The chemical problem#

Composting and manure storage lose nitrogen as ammonia and N₂O (see LE02, NU03).
Low-demanding sorption duties (odour, colour, residual organics) often use activated carbon made from coal.
Feed mills use clay binders against mycotoxins (FD04), with limited range.

Product overview#

Co-composting additive — 5–20 % biochar in compost piles with poultry litter or manure.
Litter and slurry additive — reduces ammonia and odour in barns.
Feed additive — small doses (around 1 % of diet) studied for gut health, toxin binding and emissions; authorization differs by country.
Sorbent — for wastewater polishing, stormwater filters and immobilizing metals or organics in contaminated soil (RM02).

Active ingredient / Composition#

High-surface-area biochar (often activated or produced at higher temperature for sorption); food/feed grade requires certified clean feedstock and contaminant testing.

Key facts#

Parameter	Value
Composting	Adding biochar to composting poultry litter increased nitrogen retention and lowered greenhouse-gas emissions in trials
Feed	Reviews report mixed but often positive effects on weight gain, feed efficiency and toxin binding; evidence quality varies
Sorption	Effective for many metals and organic contaminants; performance depends on biochar type and contaminant
Regulation	Feed use needs feed-material or feed-additive status (e.g. EU feed-material catalogue entry for plant charcoal); sorbents follow water-treatment rules

Advantages#

Same product as CR01, with higher-value outlets.
Lowers nitrogen losses and odour at the source.
Renewable, lower-footprint alternative to coal-based carbon for many duties.
The carbon still ends up in soil when compost or manure is applied — removal value is kept.

Mode of action#

Porous surface adsorbs ammonia, odour compounds and organic molecules; surface functional groups bind metals.
In compost, biochar improves aeration and moisture, shifting microbial processes and lowering N₂O formation.
In the gut, adsorption of toxins and changes in microbial fermentation are proposed mechanisms.

Application#

Situation	Target	Method, timing and specifics
Poultry-litter or manure composting	N retention, emissions	5–20 % biochar mixed at pile set-up
Barns	Ammonia, odour	Biochar in litter or slurry (with LE02 measures)
Feed mills (where authorized)	Gut health, toxin binding	Certified feed-grade biochar at low inclusion; test against the specific toxin
Effluent polishing, contaminated soil	Sorption	Biochar filters or soil amendment, chosen per contaminant

Limitations#

Feed use: authorization status varies, and quality control of feedstock and contaminants is essential.
Sorption is contaminant-specific; high-performance activated carbon is still needed for demanding duties.
Effects in compost and manure vary with dose and system.

Biochar made by clean pyrolysis of crop, forestry and processing residues — used as a soil amendment and sold as durable carbon removal — instead of open burning, dumping or landfilling of those residues

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: open burning and dumping of residues · Scope: agriculture and carbon removal · Evidence: high (carbon persistence, tropical soils), medium (fertile temperate soils)

The chemical problem#

Large volumes of straw, husks, shells and prunings are burned or dumped each year (see WC01), releasing smoke and greenhouse gases.
Soils in much of the tropics are acidic and low in organic matter; lime and fertilizer are the default fixes.
Carbon-removal buyers need durable removals; biochar is one of the few already sold at volume.

Product overview#

Pyrolysis biochar — biomass heated to roughly 400–700 °C with little oxygen; the gases are burned for heat or power.
Uses in agriculture — soil amendment (often co-composted or nutrient-charged first), growing-media component (CE01), carrier for microbial inoculants.
Carbon-removal credits — certified biochar removals sold on voluntary markets, adding income to the plant.
Feedstocks — rice husk, straw, coconut and nut shells, palm residues (EFB), sawmill residues, prunings; avoid contaminated feedstocks.

Active ingredient / Composition#

Stable aromatic carbon (typically >50 % C, often >70 %), ash minerals (K, Ca, Mg, P), high porosity and surface area; properties depend on feedstock and temperature.

Key facts#

Parameter	Value
Crop yield	Meta-analysis: average yield gain around 10 %, strongest on acidic and sandy tropical soils; often no gain on fertile temperate soils
Carbon persistence	A large fraction of biochar carbon persists for centuries in soil
Climate potential	Sustainable biochar could offset a meaningful share of global emissions when residues and clean kilns are used
Certification	European Biochar Certificate and carbon-registry methodologies set feedstock, emission and quality rules

Advantages#

Ends burning or dumping of the residue and stores carbon durably.
Liming effect and better water and nutrient retention on poor soils.
Two revenue streams: biochar product + carbon-removal credits.
Local production with small to medium kilns (EQ03).

Mode of action#

Pyrolysis converts labile biomass carbon into condensed aromatic carbon that microbes decompose very slowly.
In soil, biochar raises pH, cation-exchange capacity and water holding, and gives microbes a habitat; charged biochar also carries nutrients.

Application#

Situation	Target	Method, timing and specifics
Acidic, low-fertility tropical soils	Yield, pH	5–20 t/ha once, ideally co-composted or nutrient-charged; trial strips first
Rice and nut-processing hubs	Residue disposal	Pyrolysis plant at the mill; char sold to farms and carbon buyers
Plantations (palm, sugarcane)	Residue + soil	EFB/bagasse biochar returned to the estate (BR02)
Carbon projects	Removal credits	Certified production with measured feedstock, emissions and application

Limitations#

Soil response is variable — little benefit on fertile soils; raw biochar can temporarily tie up nutrients.
Feedstock must be clean (no treated wood, plastics, heavy metals); PAH and dioxin limits apply.
Dirty kilns cancel the climate benefit.
Carbon-credit prices and methodologies are still evolving.

Biodegradable scrub particles and exfoliants instead of polyethylene microbeads

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: PE/PP/PET microbeads, micro-glitter · Scope: rinse-off cosmetics · Evidence: high

The chemical problem#

A single shower-peeling product could carry hundreds of thousands of polyethylene beads — designed to wash straight into the drain, too small for any treatment plant, ending in rivers, fish and salt.
The US Microbead-Free Waters Act (2015), the UK ban (2018) and now the EU REACH restriction on intentionally added microplastics (Reg. (EU) 2023/2055) turned the category from niche concern into law, with transition windows into 2027+.
Polyester/aluminium glitter is the same particle problem with sparkle.

Product overview#

Wax beads: jojoba ester and carnauba microspheres — spherical like PE beads (same sensory roll), fully biodegradable.
Cellulose particles: wood/pulp-derived granules and the newer bacterial cellulose powders — dense, soft, tunable.
Mineral/natural grit: silica, ground apricot shell, olive pit, pumice — the traditional answer, reformulated for gentleness (roundness).
Biodegradable glitter: cellulose-core, plant-metallic finish — the party substitution.
Toothpaste abrasive switch: hydrated silica/chalk instead of PE specks (done industry-wide in the EU).

Active ingredient / Composition#

Jojoba esters (C18–C22 wax esters), carnauba wax beads (coated spheres 100–1,000 µm).
Microcrystalline cellulose / cellulose acetate-free grades; bacterial cellulose (Polybion-type).
Silica (hydrated), shells/kernels ground and sieved.

Key facts#

Parameter	Value
Class	Biodegradable particulate exfoliants
Particle size	100–1,000 µm (above the microplastic size concern once biodegradable anyway)
Regulatory	EU 2023/2055 leaves wax/cellulose/shell particles outside the restriction

| Sensory | Wax beads closest to PE feel; shells more aggressive |

Advantages#

Drop-in sensory with wax beads — reformulation risk is low; premium brands did it years ago.
Same supply chains as CM01/FI01 (waxes, cellulose, fermentation) — no new chemistry to invent.
Marketing turns a liability (banned ingredient) into a claim (biodegradable exfoliant).
Degradation: waxes/cellulose are food for wastewater microbes — no persistence pathway.

Mode of action#

Physically: rounded particles mechanically debride the skin surface — geometry, not polymer identity, does the job.
Biologically: esters/cellulose hydrolyze (lipases/cellulases) to fatty acids and sugars in sludge and water.

Application#

Product	Target	Method, timing and specifics
Face scrub	PE bead exit	Jojoba/wax microspheres 250–500 µm; density-matched to base
Body scrub	Volume exfoliant	Shell/kernel grit or salt/sugar base with wax beads for feel
Toothpaste	Abrasive	Hydrated silica (RDA-tuned); PE already phased in EU
Festival/kids glitter	Polyester glitter	Cellulose-core biodegradable glitter

Limitations#

Cost premium over PE beads (cents per unit, but margins matter in mass retail).
Natural grit irregularity needs QC for gentleness claims.
“Biodegradable” claims need standards discipline (ask for test data, not adjectives).
The EU restriction’s transition periods mean non-compliant stock persists in some markets until deadlines.

Evidence of displacement — D3: proven displacement at scale#

Assessment (hand-reviewed): EU+: plastic microbeads in rinse-off cosmetics down 97.6% (2012–2017, Cosmetics Europe data to ECHA).

Biodegradable, bio-based lubricants and hydraulic fluids (vegetable-oil and synthetic esters) — instead of mineral-oil lubricants in forestry, agriculture, marine, rail and water-adjacent machinery

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: mineral-oil lubricants in environmentally sensitive uses · Scope: machinery · Evidence: high

The chemical problem#

Large volumes of lubricants are lost directly into the environment: a chainsaw loses all its bar oil into the forest, and hydraulic hoses burst in harvesters and dredgers. Stern tubes on ships leak oil into water. Mineral oils are poorly biodegradable and toxic to aquatic organisms.

Product overview#

Environmentally acceptable lubricants (EALs):

Biodiesel, renewable diesel (HVO) and SAF instead of fossil diesel and heating oil

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: fossil diesel, heating gas-oil, part of jet fuel · Scope: FAME/HVO/SAF · Evidence: high

The chemical problem#

Diesel exhaust is an IARC Group 1 carcinogen, and older fleets across the Global South run on high-sulfur diesel.
Used cooking oil (UCO) and tallow are waste streams that, untreated, get dumped into drains and waterways; palm-oil milling leaves POME with its methane.
Jet fuel has no electric shortcut at scale — combustion kerosene will be with us for decades.

Product overview#

FAME biodiesel (transesterification of vegetable oils, UCO, tallow with methanol): B7 blends are standard in Europe; B100 runs Brazil’s truck fleets; UCO-based B100 is common in city buses of the Gulf and Asia.
HVO / renewable diesel (hydrotreating oils and fats): a drop-in fuel — no engine or logistics change, winter-grade, near-zero sulfur/aromatics; produced at multi-million-tonne scale globally.
SAF (HEFA route): the same hydrotreating chemistry finished for jet specs; the EU ReFuelEU mandate starts in 2025 (2 % SAF at EU airports, rising).
Feedstock ladder: UCO/tallow > POME/residues > oil crops (land-use caveats as with EN02 ethanol).

Active ingredient / Composition#

FAME: C16–C18 fatty-acid methyl esters; cetane 48–65; oxygenated (~10 % O); needs cold-flow care above B20 in winter.
HVO: iso-/n-paraffins C15–C18; cetane 70+; sulfur-free; chemically not an ester — no ester stability issues.
SAF HEFA: paraffinic kerosene/aromatics within ASTM D7566 annexes; blended ≤50 % with fossil Jet A-1.

Key facts#

Parameter	Value
Class	Bio-based drop-in / blend fuels
GHG	UCO/tallow routes typically 70–90 % lower WTW than fossil diesel
Compatibility	HVO: any diesel engine; FAME: B7 universal, B20–B100 needs fleet checks

| Co-products | Glycerol (FI/chemical uses), protein meals (oil-crop routes) |

Advantages#

Turns a waste problem into fuel: one tonne of dumped UCO becomes ~0.95 t of biodiesel.
HVO works in existing engines, tanks and trucks — zero-capex substitution (unlike electrification).
Removes sulfur and cuts PAH/particulates in exhaust — immediate air-quality gain for old fleets.
SAF is the only near-term lever aviation has; mandates now anchor demand.

Mode of action#

FAME: alkaline transesterification of triglycerides → methyl esters + glycerol; oxygen in the ester improves combustion.
HVO/HEFA: catalytic deoxygenation + isomerization of fatty chains to branched paraffins — renewable carbon, fossil-like molecule.

Application#

User	Target	Method, timing and specifics
City bus / truck fleet	Diesel displacement	UCO-B100 (fleet with heated filters) or HVO100 drop-in
Farm/cooperative	Autonomy	Small transesterification on oilseed press cake economy (EN02 mill logic)
Refiner	Drop-in volume	HVO co-processing or stand-alone unit on UCO/tallow slates
Airport supply	SAF mandate	HEFA-SAF book-and-claim or physical blends per ReFuelEU steps

Limitations#

Feedstock is the ceiling: waste oils cover only part of diesel demand; crop routes inherit the land debate.
FAME: cold-flow, material compatibility and NOx trade-offs at high blends; quality discipline matters (EN 14214).
UCO fraud (palm labelled as waste) is a real audit problem in import chains.
SAF HEFA is 2–4× fossil jet fuel in cost — mandate-driven, not price-driven.

Assessment (hand-reviewed): US renewable diesel grew from 0.37 to 3.7 billion gallons (2015–2024); Indonesia’s diesel imports fell from 35% to 22% of consumption (2014–2018) under its biodiesel mandate (ERIA) — still a minority of diesel.

Bioethanol as fuel and octane/oxygenate instead of MTBE, high-aromatic petrol and fossil petrol

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: MTBE, octane aromatics, part of fossil petrol · Scope: national blending programs to flex-fuel · Evidence: high

The chemical problem#

MTBE was the world’s dominant petrol oxygenate until plumes tainted groundwater across the USA (it is detectable by taste at microgram-per-litre levels and resists biodegradation); many US states banned it and the EU restricted its use in fuel. It was replaced in US reformulated gasoline largely by ethanol.
To keep octane after lead (finally banned globally in road fuel in 2021), refiners raised aromatics — including benzene, a Group 1 carcinogen — in petrol.
Oxygenate-free fossil petrol burns with more CO and particulates in older engine fleets common in the Global South.
Every litre replaced matters for GHG: petrol is the largest transport emission source.

Product overview#

Ethanol (CH₃CH₂OH) from yeast fermentation is a high-octane (RON ≈ 109), oxygen-containing (35 % O) fuel blended into petrol worldwide:

Biofilm control by enzymes and bacteriophages instead of oxidizing and non-oxidizing biocides in cooling and process water

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: continuous oxidizing/non-oxidizing biocides · Scope: cooling & process water · Evidence: emerging

The chemical problem#

Cooling and process systems stay microbe-controlled by continuous biocide dosing — oxidizers (chlorine/bromine/ClO₂) plus non-oxidizers (isothiazolinones, quats, DBNPA, glutaraldehyde).
The real enemy is biofilm, not planktonic bacteria: film insulates (energy loss), corrodes and shelters Legionella; kill-everything dosing attacks the easy fraction.
Discharged biocides and their by-products stress receiving waters (E-series logic); quats/isothiazolinones carry aquatic-toxicity flags and AMR-adjacent selection pressure (E10).

Product overview#

Biofilm-dispersive enzymes: proteases/pectinases/amylases that digest the extracellular polymeric matrix, releasing film to filtration and making residual biocide hit plankton only. Commercial in paper-machine water and growing in cooling niches.
Bacteriophage cocktails: host-specific phages against Pseudomonas/Legionella biofilms — pilot-scale in industrial water; the aquaculture/food siblings (F01, P04) are further ahead.
Monitoring-driven dosing: ATP/flow-cytometry biofilm sensors + dosing automation — the diagnose→threshold→treat pattern that cut antibiotics in V01 applied to water. Often halves biocide consumption alone.
Physical side: side-stream filtration, UV on make-up — not biological, but the frame.

Active ingredient / Composition#

Enzyme concentrates (protease-dominant blends) dosed ppm-level, compatible windows with oxidizers managed;
Phage cocktails 10⁶–10⁸ PFU/mL products, strain-matched (monitoring follows resistance).

Key facts#

Parameter	Value
Class	Enzymatic / biological biofilm control (emerging)
Status	Niche commercial (paper, some cooling); pilots elsewhere
Immediate lever	Sensor-driven dosing typically −30–60 % biocide

| Legionella | Management plans remain mandatory; biology complements, not replaces, responsibility |

Advantages#

Cuts biocide purchase, discharge toxicity and corrosion-from- overdosing at once.
Enzymes/phages are non-persistent — no discharge flags.
Better heat-transfer (film control) pays energy dividends the biocide never did.

Mode of action#

Enzymes hydrolyze EPS proteins/polysaccharides → film detachment; synergetic with low-level residual biocide.
Phages infect and lyse film bacteria in situ, replicate locally, self-dose where the target is.

Application#

Site	Target	Method, timing and specifics
Paper-machine water	Slime/breaks	Enzyme dosing established practice
Open cooling tower	Biocide load	Biofilm sensors → dosing automation; enzyme polish; phage pilots

| Discharge-limited site | Toxicity flags | Shift biocide mass down via monitoring before adding biology |

Limitations#

Emerging honesty: full biocide-free cooling at general industrial reliability is not yet proven; this article rates Partial and stays on watch.
Phage coverage is strain-specific and needs refresh; enzymes are substrate-specific (blend to the film).
Legionella responsibility means oxidizer backup usually stays — the goal is minimizing, not heroics.

Evidence of displacement — D1: works, adoption not proven#

Assessment (hand-reviewed): Mismatch: 40% of UK supermarket potatoes treated with phages is post-harvest (see P04), not water biofilm control.

Biogas and biomethane from organic waste instead of firewood, charcoal, LPG and diesel

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: firewood/charcoal cooking, LPG, diesel gensets · Scope: digesters at every scale · Evidence: high

The chemical problem#

Household air pollution from cooking with wood, charcoal, dung and coal kills an estimated 3 million people a year (WHO); the victims are mostly women and children in Africa, South Asia and the CIS countryside.
Charcoal and firewood drive deforestation around cities in Africa and the Middle East; charcoal-making also emits methane.
LPG and natural gas are fossil fuels with price and currency exposure (an acute problem for LPG-importing countries).
Diesel generators on farms and in villages combine fuel cost, exhaust particulates and noise.

Product overview#

An anaerobic digester turns dung, food waste, slaughterhouse or crop residues into biogas (55–70 % methane) plus a digestate fertilizer, using the same methanogenic microbes that work in animal stomachs and wetlands:

Biological desulfurisation of biogas and sour gas instead of chemical scrubbing

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: caustic scrubbing and chemical scavengers · Scope: biogas, landfill gas, some sour gas · Evidence: moderate

The chemical problem#

Biogas and landfill gas contain hydrogen sulfide (hundreds to thousands of ppm) that corrodes engines and boilers and must be removed before use or grid injection.
Conventional removal uses caustic soda scrubbing, iron-oxide or iron-chelate scavengers, or liquid-redox processes — continuous chemical purchases and spent-chemical waste.

Product overview#

Biological desulfurisation uses sulfide-oxidising bacteria (Thiobacillus, Thioalkalivibrio and others):

Biological wastewater treatment and bio-coagulants instead of alum, ferric chloride and synthetic polyelectrolytes

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: alum/PAC, ferric chloride, synthetic polyelectrolytes · Scope: WWTP process choice + natural coagulants · Evidence: high for biology, medium for bio-coagulants

The chemical problem#

Conventional plants chase suspended and colloidal pollution with alum or ferric chloride: every tonne of chemical brings tonnes of acidic chemical sludge to dewater and landfill, plus aluminium or iron residuals and rising salinity in the effluent.
Synthetic polyacrylamide flocculants improve settling but carry residual acrylamide monomer — a neurotoxin and probable carcinogen (IARC 2A) with strict drinking-water limits.
High upstream chemical loads also raise chlorine demand downstream, increasing disinfection by-products (links: ecology E05 wetlands).
In much of Africa, the Middle East and Latin America the real problem is different: agro-industry (dairy, slaughterhouses, starch, palm/sugar mills) discharges untreated organic effluent because chemical treatment looks expensive — exactly where biology is cheapest.

Product overview#

Treat the organics with microbes first; use chemistry only for the residual polish:

Biomass district heating instead of heating oil and coal

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: heating oil and coal · Scope: district heating and CHP · Evidence: high

The chemical problem#

In the 1970s Nordic district-heating networks ran mostly on imported heating oil; the oil crises made heat expensive and insecure.
Coal and oil plants emit CO₂ and sulphur, and every litre was imported.

Product overview#

Biomass district heating burns low-value wood fuels — forestry residues, sawmill by-products, bark, recovered wood, pellets and straw — in large boilers and CHP plants feeding hot-water networks. Sweden’s switch was driven by the oil shocks, then by its carbon tax (1991), which made fossil heat uncompetitive. Finland, Denmark, Austria and the Baltic states followed.

Biopreservation of raw and minimally processed food with bacteriophages, protective cultures and bacteriocins (nisin) — instead of chlorine washes and part of synthetic preservatives

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: chlorine washes and part of synthetic preservatives · Products: raw and minimally processed foods · Evidence: high for specific targets

The chemical problem#

Chlorine washes are the standard sanitizer for fresh-cut produce and (outside the EU) poultry carcasses. They form chlorate and trihalomethanes. EFSA (2015) found chlorate exposure a concern for infants and children (iodine uptake inhibition), and the EU set chlorate MRLs in 2020. Chlorine loses activity quickly in organic-rich water, so pathogen cross-contamination still happens. Synthetic preservatives face consumer demand for “clean label”.

Biosurfactant and APG cleansing — sophorolipids, rhamnolipids, alkyl polyglucosides — instead of petrochemical SLES/SLS

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: SLES/SLS and ethoxylate chains · Scope: personal & household cleansing · Evidence: medium, scaling

The chemical problem#

The world washes with SLES/SLS: sulfated petro (or palm-oleo) alcohols, whose ethoxylation leaves the 1,4-dioxane trace concern and whose carbon is fossil wherever the C12 chain is petro.
Conventional anionic surfactant loads stress wastewater biology (E10’s territory).
Consumer labels have moved faster than the chemistry aisle: “sulfate-free” is a claim, and what fills it is often another petro surfactant.

Product overview#

Sophorolipids (yeast Starmerella bombicola fermentation of sugars/oils): glycolipid biosurfactants, fully biobased, low aquatic toxicity, hard-water tolerant — commercial in premium/dishwash/institutional niches.
Rhamnolipids (bacterial fermentation): strong Wettability/ emulsification; producers scaling (watch the Pseudomonas production-organism story for permits).
Alkyl polyglucosides (APG): glucose + fatty alcohol condensation — the today answer at scale: biodegradable, gentle, already commodity-priced in Europe (E10’s workhorse recommendation).
Blends logic: biosurfactant as active/co-surfactant with APG gets premium performance without full-cost exposure.

Active ingredient / Composition#

Sophorolipids: acidic/lactonic forms CMC ~40–100 mg/L; used 1–10 % of formulation.
APG: C8–C16 glucosides, 50 % active aqueous pastes; the formulation base.

Key facts#

Parameter	Value
Class	Glycolipid biosurfactants / sugar surfactants
Biodegradability	Readily biodegradable; low aquatic toxicity
Carbon	Sugar + plant oil routes (EN02/FI feedstock belt)

| Cost | APG ≈ commodity; sophorolipids premium but falling with capacity |

Advantages#

Removes the dioxane-trace story and the fossil carbon of the sulfate chain.
Works in hard water and cold washes (energy-adjacent benefit).
Fermentation production from sugars — supply sitable in this index’s regions.

Mode of action#

Same colloid physics as any surfactant (micelles, CMC, detergency) with sugar head-groups replacing sulfate/ethoxylate heads; biology only changes where the molecule comes from — the FPC lesson (FI05) again.

Application#

Product	Target	Method, timing and specifics
Premium shampoo/body wash	Sulfate-free claim	APG base + sophorolipid active; viscosity engineering
Dishwash/institutional	Performance + discharge	Sophoro/rhamnolipid blends; hard-water trials
Household cleaners	E10 program	APG + enzymes (E10’s existing recommendation)

Limitations#

Cost gap vs SLES at commodity wash loads (honest Partial).
Foaming profile differs (consumer re-education in some markets); formulation work per product.
Fermentation capacity concentrated in few producers — supply scale-up risk.
Rhamnolipid production-organism permitting in some jurisdictions.

Evidence of displacement — D1: works, adoption not proven#

Assessment (hand-reviewed): No displacement: petrochemical and oleochemical surfactants still hold >95% of the market.

Biosurfactants (rhamnolipids, sophorolipids) instead of petrochemical surfactants in cleaning and industrial formulation

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: LAS, AEO and solvent-based cleaners · Scope: cleaning, industry, adjuvants · Evidence: medium-high

The chemical problem#

Surfactants are the largest class of synthetic chemicals in daily use - hundreds of millions of tonnes per year across detergents, cleaners, personal-care products and industrial processes. The workhorses, LAS and alcohol ethoxylates, start as petrochemicals; alkylphenol ethoxylates degrade to nonylphenol, an endocrine disruptor banned or restricted across the EU and beyond; the surfactant load in laundry and cleaner wastewater is a main driver of aquatic toxicity in urban rivers; and heavy-duty industrial cleaning still leans on solvents (see I01) with VOC and worker-exposure baggage.

Bumblebee pollination instead of hormone sprays and manual vibration in greenhouse tomatoes

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: synthetic auxin sprays and manual vibration · Scope: greenhouse tomatoes · Evidence: moderate

The chemical problem#

Tomato flowers need buzz pollination to set fruit; there is no wind or insect activity in a closed greenhouse.
Before bumblebees, growers sprayed synthetic auxins (4-CPA, “tomatotone”) on each truss or vibrated flowers by hand with electric wands — labour-heavy and, with hormones, prone to malformed and hollow fruit.

Product overview#

Commercial bumblebee colonies (Bombus terrestris, mass-reared since the late 1980s in Belgium and the Netherlands) are placed in the greenhouse; worker bees buzz-pollinate the flowers. Bumblebee pollination also pushes growers towards biological pest control (CE03), because most insecticides kill the bees.

Cassava mealybug classical biological control with Anagyrus lopezi instead of insecticides

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: insecticides and unchecked losses · Scope: cassava in sub-Saharan Africa · Evidence: high (control), moderate (as a chemical displacement)

The chemical problem#

The cassava mealybug (Phenacoccus manihoti) arrived in Africa from South America around 1973 and spread across the cassava belt, causing yield losses of up to 80 %.
Insecticides were the only conventional answer, but they were expensive, rarely available to smallholders and impractical over millions of hectares — so in practice most farmers had no control.

Product overview#

Classical biological control: the parasitoid wasp Anagyrus lopezi, found in the pest’s native range in South America, was mass-reared and released from 1981 by IITA and partners, including from aircraft. It established in 26 African countries and spread on its own, without any farmer having to buy or apply anything.

Cattle tick control with the Bm86 anti-tick vaccine, tick-resistant breeds, pasture spelling and entomopathogenic fungi (Metarhizium)

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: frequent chemical acaricide treatments · Species: cattle · Evidence: medium–high

The chemical problem#

The cattle tick Rhipicephalus (Boophilus) microplus (tropics and subtropics) and, in temperate regions including southern Russia, Hyalomma, Dermacentor and Ixodes species transmit babesiosis, anaplasmosis, theileriosis and (to humans) Crimean-Congo haemorrhagic fever (Hyalomma, a notifiable disease in southern Russia). Intensive acaricide use has created multi-resistant tick populations (OPs, pyrethroids, amitraz, ivermectin, fipronil) in Latin America, Australia, Africa and India. OP dips expose workers (neurotoxicity), and dip-waste disposal pollutes water.

Citric acid by Aspergillus niger fermentation instead of extraction from citrus fruit

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: citrus-fruit extraction · Scope: all commercial citric acid · Evidence: high

The chemical problem#

Until the 1920s citric acid came from lemon and lime juice, precipitated as calcium citrate. Supply was tied to fruit harvests and concentrated in Sicily, with large price swings.
Demand for the acidulant in soft drinks, food, detergents (as a phosphate-free builder) and pharmaceuticals far outgrew what fruit could supply.
The old route needed about 30–40 t of lemons per tonne of acid and left the rest of the fruit as a processing problem.

Product overview#

Fermentation citric acid: Aspergillus niger strains overproduce citric acid from cheap sugars (cane or beet molasses, sucrose, glucose syrups from maize or cassava) under iron- and manganese-limited, low-pH conditions. Pfizer commercialised surface fermentation in the 1920s; submerged fermentation became dominant after World War II. Today the product is a commodity made at the million-tonne scale, mostly in China.

Composting and anaerobic digestion of separately collected biowaste instead of landfill

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: landfilling of organic waste · Scope: municipal and commercial biowaste · Evidence: moderate

The chemical problem#

Food and garden waste is the largest single fraction of municipal waste. In a landfill it rots anaerobically and releases methane and contaminated leachate for decades.
Mixed with other waste, it also makes recycling and incineration less efficient.

Product overview#

Separate collection plus biological treatment:

Conifer root and butt rot (Heterobasidion) prevention by stump treatment with the competitive fungus Phlebiopsis gigantea (Rotstop) — instead of chemical stump treatments

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: urea and borate stump treatments · Scope: forest thinning and harvesting · Evidence: high

The chemical problem#

Heterobasidion annosum s.l. (root and butt rot) is one of the most economically damaging forest diseases in the Northern Hemisphere, causing large losses of spruce timber in Europe. Spores infect fresh stumps after thinning, and the fungus spreads through roots to neighbouring trees. Chemical stump protection uses urea or borates, and borates are classified as reproductive toxicants in the EU.

Constructed (treatment) wetlands for villages, farms, small towns and stormwater — instead of chemical precipitation, chlorination of effluent, or discharge of untreated wastewater

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: chlorination and chemical treatment of small wastewater flows, and untreated discharges · Scope: rural and peri-urban · Evidence: high

The chemical problem#

Many small settlements lack treatment, or use septic tanks or basic plants that discharge partly treated water. Lake Baikal’s shores show algal blooms (Spirogyra) and ecosystem damage linked to wastewater from settlements, and the Volga carries large nutrient loads. Where small plants exist, chlorination of effluent produces trihalomethanes and other by-products that are toxic to aquatic life, and chemical phosphate removal creates metal sludges.

Controlled fruit ripening with ethylene (including ethylene from bio-ethanol) in ripening rooms — instead of calcium carbide

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: calcium carbide ripening · Products: climacteric fruit · Evidence: high

The chemical problem#

In South and Southeast Asia, Africa and parts of the Middle East, traders ripen mangoes, bananas and papayas by putting calcium carbide packets in fruit boxes. Moisture releases acetylene, a weak ethylene analogue. Industrial carbide is contaminated with arsenic and phosphorus compounds, which can form arsine and phosphine gases. Workers and consumers are exposed, and the fruit colours on the outside while staying unripe and poor-tasting inside. Food-safety authorities in India, Bangladesh, Pakistan, Nigeria, Kenya and other countries prohibit it, yet enforcement is weak. Imported fruit from these regions can reach any market, including Russia.

Copper (and nickel/cobalt) recovery from low-grade and secondary sulfide ores by heap and dump bioleaching + SX-EW — instead of concentration and smelting

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: smelting of low-grade sulfide ores · Scope: base-metal mining · Evidence: high for copper

The chemical problem#

Smelting sulfide ores releases SO₂, arsenic, lead and cadmium particulates, and uses large amounts of energy. The Norilsk industrial area has been among the largest point sources of SO₂ in the world, and smelter pollution has created large dead forest zones around it. Low-grade ores and waste dumps cannot be processed economically by smelting at all.

Crop disease forecasting models, spore traps, pheromone and smart pest traps and field diagnostics — spray when risk is real instead of calendar-based fungicide and insecticide programmes

Mon, 01 Jan 0001 00:00:00 +0000

Replaces (partial): calendar-based spray programmes · Scope: potato, grape, apple, cereals, vegetables, orchards · Evidence: high (decision support), medium (automated spore traps)

The chemical problem#

Many farms spray protectant fungicides every 7–10 days “just in case”, and insecticides on fixed dates, regardless of real infection or pest pressure.
With protectants like mancozeb and chlorothalonil leaving the EU market, every remaining spray has to count.
EU law already requires integrated pest management (Directive 2009/128/EC): monitoring and thresholds before treatment.

Product overview#

Disease forecasting models — weather-driven infection-risk models (late blight, apple scab, grapevine downy/powdery mildew, septoria, fusarium) delivered as apps or advisory services.
Spore traps — air samplers that catch fungal spores; with qPCR or image analysis they detect inoculum before symptoms appear.
Pheromone and smart traps — lure traps for moths and fruit flies, increasingly with cameras and automatic counting (links to A37).
Field and lab diagnostics — molecular plant-pathogen tests (PCR, LAMP, ELISA) for seed, planting material and outbreaks.
Remote sensing — satellite and drone imagery to target scouting.

Active ingredient / Composition#

Information: weather data, models, trap counts, pathogen DNA tests. Inputs are sensors, traps, lures, reagents and software.

Key facts#

Parameter	Value
Decision-support systems	Reviews of predictive systems show reliable spray reductions where models are validated locally
Air sampling	Molecular detection in spore traps gives days of warning before visible disease
Pheromone monitoring	Standard in IPM orchards and cotton; thresholds set per pest
Regulation	IPM obligation in the EU (Directive 2009/128/EC); buyer standards (GLOBALG.A.P.) ask for monitoring records

Advantages#

Fewer sprays for the same protection → lower cost, fewer residues.
Better timing makes each spray (biological or chemical) more effective.
Monitoring data documents IPM compliance for buyers and regulators.
Makes biological products viable: they work best when applied at the right moment.

Mode of action#

Models calculate infection periods from leaf wetness, temperature and humidity; sprays are applied only before or just after a risk period.
Spore traps measure the presence of inoculum; no inoculum, no spray.
Trap counts compared with thresholds trigger treatment only when needed.

Application#

Crop	Target	Method, timing and specifics
Potato	Late blight	Forecast-based spraying; combine with resistant varieties (SG01)
Grapevine	Downy/powdery mildew	Infection models + spore traps; fewer sprays on PIWI varieties
Apple	Scab, codling moth	Scab infection models; pheromone traps and degree-day models for moth timing
Cotton, vegetables	Bollworms, fruit flies	Pheromone traps with action thresholds
Seed and planting material	Clean start	PCR/ELISA testing of seed lots and plantlets

Limitations#

Models must be validated for local climate and varieties.
Requires weather stations, trap maintenance and farmer trust.
Advisory services in many regions are weak; smallholders need cooperative or input-dealer support.
Some pathogens and pests lack validated models.

Assessment (hand-reviewed): Adjacent: biocontrol-based IPM on >90% of Dutch greenhouse tomato, cucumber and pepper; threshold-based programmes cut insecticide applications by 44% vs calendar spraying (multi-country meta-analysis, peer-reviewed). Automated-trap adoption: market research only.

Crop residues (rice and wheat straw, cane trash) managed by in-situ incorporation with microbial decomposers, mulching and collection for biogas/bio-CNG instead of open-field burning

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: open-field residue burning · Scope: rice–wheat, sugarcane, cereals · Evidence: high (harm, mechanical and ex-situ options), low–medium (decomposer sprays)

The chemical problem#

North-west India burns millions of tonnes of rice straw every October–November to clear fields for wheat; the smoke is a major driver of Delhi’s winter air pollution.
Burning releases PM2.5, black carbon and polyaromatic hydrocarbons, and destroys nitrogen, sulfur and organic carbon that the next crop needs.
Pre-harvest cane burning and stubble burning happen across South and Southeast Asia, Africa and Latin America.

Product overview#

In-situ management — happy seeder / super seeder sow wheat directly into rice stubble (straw stays as mulch); mulchers and incorporation tillage.
Microbial decomposers — fungal/bacterial consortia (e.g. Trichoderma, Aspergillus, cellulolytic bacteria) sprayed on straw to speed decomposition (India’s public “Pusa decomposer” and commercial products).
Ex-situ use — baling straw for bio-CNG/biogas, power plants, pellets, fibre boards and packaging.
Pyrolysis to biochar — small kilns that turn residues into a soil amendment instead of smoke.

Active ingredient / Composition#

Decomposer consortia: cellulolytic and lignolytic fungi and bacteria, sold as capsules, powders or liquid concentrates; applied at a few litres of prepared culture per hectare with water.
Ex-situ: straw bales as feedstock (rice straw ~1.5–2 t/ha dry matter per t grain).

Key facts#

Parameter	Value
Alternatives assessed	Analysis of 10 residue-management options in India found happy-seeder sowing most profitable and least polluting; burning among the worst on social cost
Policy	India’s central sector scheme for in-situ crop-residue management (since 2018) subsidizes machines; burning is prohibited by law in the affected states
Decomposers	Field evidence on decomposition speed within the 2–3-week rice–wheat window is limited and mixed
Bio-CNG	Rice straw is used commercially as a bio-CNG feedstock in India (compressed biogas plants)

Advantages#

Ends a seasonal public-health crisis while keeping N, S and carbon in the soil.
Mulch conserves water and suppresses weeds in the following wheat.
Ex-situ routes create rural income from a residue (bio-CNG, pellets, board).
Biochar and incorporation add stable carbon (carbon-credit potential).

Mode of action#

Mulch and incorporation return lignocellulose to soil; soil microbes mineralize it over the following season.
Decomposer cultures add cellulases and ligninases to start breakdown faster — useful if moisture and temperature allow.
Anaerobic digestion converts straw carbohydrates to methane; digestate returns nutrients (see NU03).

Application#

Situation	Target	Method, timing and specifics
Rice → wheat, short window	Sow without burning	Happy/super seeder directly into standing stubble
Smallholders without machines	Faster breakdown	Microbial decomposer spray after harvest plus light incorporation and irrigation; do not rely on the spray alone
Near bio-CNG or power plants	Income from straw	Baling and supply contracts
Sugarcane	Avoid trash burning	Green-cane harvesting; trash blanket; bagasse/trash to energy (BR02)

Limitations#

Machines need capital and custom-hiring services; small farms depend on subsidies.
Decomposer sprays: evidence is weaker than the marketing — independent trials should precede large-scale promotion.
Straw logistics (baling, transport, storage) are costly and seasonal.
Mulch can raise pest or N immobilization issues at first.

Assessment (hand-reviewed): Punjab crop-residue burning down 87% (2020–2024) — burning fell; the microbial share of the replacement is not shown.

Dairy mastitis prevention with selective dry-cow therapy, internal teat sealants and bacteriocin (nisin) teat disinfection

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: routine antibiotic dry-cow tubes in every quarter of every cow · Species: dairy cattle · Evidence: high

The chemical problem#

Blanket dry-cow therapy (BDCT) means every quarter of every cow receives a long-acting antibiotic at drying-off, even when most cows (often 60–80 % in well-managed herds) are uninfected. BDCT is one of the largest uses of antibiotics on dairy farms, and often includes 3rd/4th-generation cephalosporins, which the WHO lists as highest-priority critically important for humans. Since 2022 the EU has banned routine prophylactic antibiotic use (Regulation (EU) 2019/6). The Netherlands introduced selective dry-cow therapy in 2013 and cut its total veterinary antibiotic sales by about 70 % (all species) without a rise in mastitis.

Dengue, Zika and chikungunya prevention with Wolbachia-infected Aedes aegypti (population replacement) and incompatible insect technique — instead of repeated insecticide fogging

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: routine fogging of cities against Aedes · Scope: urban public health · Evidence: high

The chemical problem#

Cities fight dengue mainly with insecticide fogging and temephos. Aedes aegypti is highly resistant to pyrethroids in most endemic regions, and fogging reaches few mosquitoes, which rest indoors. It exposes residents and kills pollinators. Dengue incidence has grown about 10-fold in 20 years, and invasive Aedes albopictus is spreading into southern Europe and the Russian Black Sea coast (Sochi region).

Detergent enzymes for low-temperature washing instead of phosphates, extra surfactant and hot washing

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: phosphates, part of the surfactant, hot washing · Scope: laundry and dishwashing · Evidence: moderate

The chemical problem#

Classic detergents relied on phosphate builders (sodium tripolyphosphate) and high temperatures to lift protein, starch and fat stains. Phosphates fed algal blooms; the EU banned them in household laundry detergents (2013) and automatic dishwasher detergents (2017).
Washing at 60–90 °C uses most of a washing machine’s energy; surfactants — the largest active ingredient — are mostly petrochemical.

Product overview#

Detergent enzymes break stains down catalytically at low temperature: proteases (protein stains), amylases (starch), lipases (fat), mannanases (gums), cellulases (fabric care, anti-greying) and pectate lyases (fruit). A few grams per wash replace temperature and part of the chemical load. Detergent enzymes were Novozymes’ founding mass market and remain a core of Novonesis’ household-care business.

Disease-resistant crop varieties (marker-assisted breeding, stacked resistance genes, cisgenesis) instead of routine fungicide spray programmes

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: routine protective fungicide programmes · Scope: potato, grapevine, cereals, vegetables · Evidence: high

The chemical problem#

Susceptible varieties of potato and grapevine are the most fungicide-intensive crops in temperate agriculture: 10–20 late-blight sprays per season in wet potato regions, 8–15 sprays in European vineyards.
The key protectant chemistry is disappearing: mancozeb (EU non-renewal 2021) and chlorothalonil (EU non-renewal 2019) are gone from the EU market; copper is capped at 28 kg/ha over 7 years in the EU.
Each spray adds fuel, soil compaction and residue risk, and single-site fungicides lose efficacy to resistance.

Product overview#

Marker-assisted selection (MAS) — DNA markers linked to resistance genes speed up classical breeding and allow stacking of several genes in one variety.
Resistant grape varieties (PIWI) — crosses with American/Asian Vitis carrying Rpv (downy mildew) and Run/Ren (powdery mildew) genes, back-crossed to wine quality.
Cisgenic and gene-edited resistance — inserting resistance genes from wild relatives of the same species (e.g. potato Rpi genes from wild Solanum), or editing susceptibility genes (e.g. mlo for powdery mildew).
Variety mixtures and multilines — see A14.

Active ingredient / Composition#

The “active ingredient” is a gene: e.g. potato Rpi-blb1, Rpi-blb2, Rpi-vnt1; grape Rpv3, Rpv10, Rpv12, Run1, Ren3; wheat Sr/Lr/Yr rust genes; barley mlo.
Delivered as certified seed, seed tubers or grafted vines.

Key facts#

Parameter	Value
PIWI grapes	Commonly 2–4 sprays instead of 8–15 at comparable sites (often a 50–80 % cut; depends on disease pressure and the number of resistance genes)
Late-blight-resistant potato	Stacked Rpi genes give near-complete field resistance in trials (DuRPh project, Netherlands)
Breeding time	MAS shortens a classical cycle; cisgenesis/gene editing shorten it further
Regulation	Conventional/MAS varieties: normal variety registration. Cisgenic/gene-edited: GMO rules in many countries; EU NGT proposal under negotiation; Russia: GM cultivation banned (Federal Law 358-FZ, 2016) but a federal gene-editing programme runs

Advantages#

Protection is built into the seed: no spraying equipment, no residue, no operator exposure.
Lowest cost per hectare of any disease control once the variety exists.
Works in organic farming (conventional and MAS varieties).
Stacked genes plus a few targeted sprays protect the resistance itself.

Mode of action#

Resistance (R) genes encode immune receptors that recognize pathogen effectors and trigger a hypersensitive response, stopping infection at the entry site.
Loss-of-function in susceptibility genes (e.g. mlo) removes what the pathogen needs to infect.
Quantitative (polygenic) resistance slows epidemics; it is usually more durable than single R genes.

Application#

Crop	Disease	Method, timing and specifics
Potato	Late blight	Plant resistant varieties with stacked genes; keep 1–2 sprays at high pressure to protect durability; monitor for virulent strains
Grapevine	Downy and powdery mildew	Plant PIWI varieties with ≥2 Rpv and Run/Ren genes; minimal sprays at critical stages
Wheat	Rusts, septoria	Choose varieties by national resistance ratings; diversify genes across farms
Vegetables	Mildews, viruses	Use hybrids with labelled resistance codes (e.g. HR/IR)

Limitations#

Single genes break down when pathogens evolve (rust, late blight); stacking, rotation of genes and residual sprays are needed.
Market barriers: new grape varieties are not allowed in many protected-origin wines; consumers and buyers know old potato varieties.
Gene-edited and cisgenic products face GMO rules in many markets.
Breeding takes years; resistance must be combined with yield and quality.

Assessment (hand-reviewed): Germany: disease-resistant grape varieties 3–3.5% of vineyard area.

Disease-resistant fish and shrimp lines (QTL- and genomic selection, SPF/SPR broodstock) instead of antibiotics, formalin and pond chemicals

Mon, 01 Jan 0001 00:00:00 +0000

Replaces (partial): antibiotics and chemical baths in hatcheries and ponds · Scope: salmon, trout, tilapia, shrimp · Evidence: high

The chemical problem#

Aquaculture is the fastest-growing animal production sector and, in many countries, a major user of antibiotics.
Hatcheries rely on formalin and disinfectants; shrimp ponds receive antibiotics and chemicals during outbreaks of AHPND/EMS and white spot.
Viral diseases (IPN, ISA, white spot) cannot be treated at all — only prevented.

Product overview#

QTL/marker selection — the classic case: a major QTL for infectious pancreatic necrosis (IPN) resistance in Atlantic salmon; marker-selected eggs became standard in Norway and IPN outbreaks fell dramatically.
Genomic selection — breeding values for resistance to sea lice, pasteurellosis, AHPND, white spot, using SNP chips.
SPF/SPR shrimp broodstock — specific-pathogen-free (and specific-pathogen-resistant) lines from biosecure nucleus centres (see F04).
Genetically improved tilapia (GIFT and successors) — faster growth plus disease-tolerance selection.

Active ingredient / Composition#

Eggs, fry, post-larvae or broodstock from a selected line, with a disease-resistance breeding value or marker status.

Key facts#

Parameter	Value
IPN salmon	One QTL explains most genetic variation in IPN resistance; marker-assisted selection cut outbreaks in Norwegian farms
Shrimp	SPF lines are the global standard for P. vannamei; resistance screening for AHPND/WSSV is offered by leading breeders
Response to selection	Disease-resistance traits often have moderate heritability → measurable gains each generation
Regulation	Conventional selection: no special approval; gene-edited fish are GMOs in the EU and Russia

Advantages#

Prevents diseases that have no drug treatment.
Lower mortality → less feed wasted per kg harvested.
Gains are cumulative and delivered through the normal egg/post-larvae trade.

Mode of action#

Natural genetic variants change host-pathogen interaction; e.g. the IPN-resistance QTL is linked to the epithelial cadherin gene, which the virus uses to enter cells.
Selection on challenge-test data (sib testing) raises the frequency of resistance alleles in the population.
SPF status removes pathogens at the start of the production chain.

Application#

Species	Disease	Method, timing and specifics
Atlantic salmon	IPN, sea lice	Buy QTL-selected eggs; combine with vaccination (F01) and cleaner fish (F02)
Shrimp	AHPND, WSSV	Stock SPF/SPR post-larvae from accredited broodstock centres; PCR-test batches (DX01)
Tilapia	Streptococcosis, growth	Genetically improved strains plus vaccination
Sea bass/bream	Pasteurellosis, VNN	Lines selected on challenge tests

Limitations#

Resistance is disease-specific; new diseases appear faster than breeding cycles.
Small hatcheries buy cheap, non-selected stock; quality assurance and PCR testing are needed.

Disease-resistant livestock genetics — genomic selection, adapted breeds, gene-edited PRRS-resistant pigs — instead of routine antibiotics, acaricides and repeated mass treatment

Mon, 01 Jan 0001 00:00:00 +0000

Replaces (partial): routine antibiotics, acaricides and mass treatments in susceptible animals · Scope: pigs, cattle, poultry · Evidence: high (breeds, genomics), high-in-trials (gene editing)

The chemical problem#

Global antimicrobial use in food animals is larger than in human medicine and still growing in middle-income countries.
Viral diseases like PRRS in pigs open the door to bacterial infections, so whole groups receive antibiotics.
Tick-susceptible European cattle breeds in the tropics need acaricide dipping every 1–3 weeks (see V06); resistance to acaricides is widespread.

Product overview#

Adapted and crossbred breeds — Bos indicus and composite cattle carry far fewer ticks; local poultry and small-ruminant breeds tolerate local parasites.
Genomic selection for disease traits — breeding values for mastitis resistance, somatic cell count, hoof health, tick burden, Marek’s disease resistance (poultry).
Gene editing of host receptors — pigs with an edited CD163 receptor domain are resistant to PRRS virus; approved by the US FDA in 2025 for food use. Heat-tolerant “slick” cattle (FDA low-risk determination, 2022) are another example.
Delivery — breeding stock, semen for artificial insemination (AI) and embryos.

Active ingredient / Composition#

The trait: a gene variant or a polygenic breeding value.
Delivered as semen straws, embryos, grandparent/parent stock or crossbred replacements.

Key facts#

Parameter	Value
PRRS-resistant pigs	CD163-edited pigs showed no infection after PRRSV challenge; a commercial-scale founder population has been produced
Genomic selection	Now routine in dairy cattle; disease traits included in national selection indices in several countries
Regulation	Conventional/genomic breeding: no special approval. Gene-edited animals: approved in the USA (PRRS pigs, slick cattle), Brazil, Argentina, Colombia have case-by-case rules; EU and Russia treat them as GMOs (Russia: GM ban, gene-editing research programme)

Advantages#

Reduces the disease, not just the symptoms → fewer treatments of every kind.
Effect is permanent and cumulative over generations.
Delivered through existing AI and breeding-stock channels.

Mode of action#

PRRS virus needs the SRCR5 domain of the CD163 receptor to enter macrophages; removing that domain blocks infection without affecting other functions of the receptor.
Tick resistance in indicine cattle combines skin and immune factors that reduce tick attachment and survival.
Polygenic disease resistance shifts the herd average: fewer clinical cases, lower pathogen load.

Application#

Species	Disease	Method, timing and specifics
Cattle (tropics)	Ticks, tick fever	Crossbreed with indicine or composite bulls; combine with Bm86 vaccine and pasture management (V06)
Dairy cattle	Mastitis, lameness	Select bulls by genomic health indices; combine with selective dry-cow therapy (V04)
Pigs	PRRS	Gene-edited PRRS-resistant lines where legal; otherwise vaccination and biosecurity
Poultry	Marek’s disease, local parasites	Resistant lines and adapted local breeds for village systems

Limitations#

Gene-edited animals are not legal in many markets (EU, Russia); exporters must follow importer rules.
Breeding progress is slow (years), and selecting for disease traits can conflict with production traits.
Resistance to one disease does not remove the need for vaccination and biosecurity against others.
Smallholder access to improved genetics depends on AI services.

Drone release of beneficial insects (Trichogramma, Cotesia, predatory mites) instead of insecticide sprays

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: insecticide sprays and manual release · Scope: field-scale augmentative biocontrol · Evidence: moderate–high

The old process#

Augmentative biocontrol (releasing Trichogramma or Cotesia wasps, predatory mites) works, but walking through fields to place cards or cups costs labour and limits area — so most growers sprayed insecticides instead.

Product overview#

Drone release: a drone carries parasitised eggs or cocoons (often in biodegradable capsules or loose with carrier) and releases them along a programmed grid. In Brazil it became the default way to apply parasitoids in sugarcane and other crops; similar systems exist in China, Colombia and for predatory mites in orchards and berries.

Durable wood without toxic preservatives — furfurylated wood (from agricultural residues), acetylated wood, thermally modified wood, naturally durable species and constructive protection — instead of CCA, creosote and biocidal impregnation

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: CCA, creosote, pentachlorophenol and biocidal impregnations · Scope: construction and gardens · Evidence: high

The chemical problem#

CCA (arsenic, chromium, copper) was the standard “green” pressure-treated wood for decades. Arsenic leaches into soil and onto children’s hands. The EU restricted CCA for consumer and residential uses (Directive 2003/2/EC), and the USA ended residential use (voluntary phase-out in 2003). Old CCA wood remains in playgrounds and gardens, and burning it releases arsenic.
Creosote (on railway sleepers and poles) contains PAHs, including carcinogens. Its use is restricted in the EU, and old sleepers reused in gardens are a known hazard.
Pentachlorophenol is listed under the Stockholm Convention on persistent organic pollutants (2015).
All biocide-treated wood becomes hazardous waste at end of life.

Product overview#

Wood modification changes the wood itself so fungi and insects cannot use it, with no toxic biocides:

Edible wax and essential-oil coatings on fresh produce instead of synthetic postharvest fungicides in wax

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: fungicide-wax dips and petroleum waxes · Products: citrus, pome fruit, mango, avocado · Evidence: medium-high

The chemical problem#

Postharvest losses eat a fifth to half of the fresh produce in many supply chains, and packhouses answer with waxes carrying fungicides: imazalil and thiabendazole drenches on citrus, fludioxonil in wax, historically SOPP and biphenyl pads. These are residues on food that is often eaten with the peel; worker exposure happens in every treated line; export MRLs keep tightening; and the decay fungi themselves - Penicillium digitatum, P. italicum - have grown resistant to the standard fungicides in major citrus industries, so the old tools are losing their guarantees even before regulators move.

Enhanced biological phosphorus removal instead of chemical precipitation with metal salts

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: metal-salt precipitation · Scope: wastewater treatment plants · Evidence: moderate

The chemical problem#

Phosphorus discharge limits (EU Urban Waste Water Directive, lake protection) are usually met by dosing ferric or aluminium salts, which precipitate phosphate.
Chemical dosing is a permanent operating cost, adds sludge (metal phosphates and hydroxides), raises effluent salinity and locks phosphorus in a form that is poorly plant-available — undermining phosphorus recycling (NU04).

Product overview#

EBPR is a process configuration, not a chemical: an anaerobic zone ahead of the aerobic zone selects phosphate-accumulating organisms (PAOs) that store large amounts of polyphosphate. Phosphorus leaves the plant inside the waste sludge, ready for recovery as struvite (NU04). Variants include A2O, UCT, Bardenpho and side-stream EBPR (S2EBPR) that uses fermented sludge as carbon.

Enteric methane from cattle and sheep reduced by bromoform-containing red seaweed (Asparagopsis), essential-oil and plant-extract feed additives, and low-methane genetics — instead of unabated emissions and synthetic inhibitors alone

Mon, 01 Jan 0001 00:00:00 +0000

Replaces (partial): unabated enteric methane; synthetic-only inhibitor strategy · Scope: dairy and beef cattle, sheep · Evidence: high (Asparagopsis, controlled trials), medium (essential oils)

The chemical problem#

Rumen microbes turn part of the feed energy into methane, which the animal belches out — the largest agricultural methane source and a 2–12 % loss of gross feed energy.
Policy is arriving: Denmark adopted a carbon tax on livestock emissions from 2030; New Zealand and the EU are designing pricing or reporting schemes; dairy buyers set supplier targets.
The best-documented additive, 3-NOP (Bovaer), is a synthetic molecule; ionophores (monensin) used for rumen efficiency are antimicrobials.

Product overview#

Asparagopsis red seaweed (A. taxiformis, A. armata) — contains bromoform, which blocks the last step of methane formation. Fed at well under 1 % of diet organic matter.
Essential-oil and plant-extract blends — e.g. coriander-seed/eugenol/geranyl blends (Agolin Ruminant) with EU-recognized moderate methane reductions; garlic/citrus products in development.
Tannin- and saponin-rich forages and extracts — modest reductions with co-benefits (parasite control, see V05).
Low-methane genetics — methane yield is heritable; some countries are adding it to breeding indices (see SG03).
Comparator: 3-NOP (synthetic) — 20–35 % typical reduction, EU-approved 2022.

Active ingredient / Composition#

Asparagopsis: bromoform (CHBr₃) and other halogenated compounds; freeze-dried or oil-steeped product.
Essential-oil blends: coriander seed oil, eugenol, geranyl acetate (and similar).
Tannins: condensed tannins (quebracho, mimosa, forage legumes like sainfoin).

Key facts#

Parameter	Value
Asparagopsis, beef steers	Methane reduced by >80 % over 21 weeks in a controlled feeding trial, without hurting growth
3-NOP, dairy cows	~30 % persistent reduction over 12 weeks (comparator)
Essential-oil blend	Meta-analysis: methane per kg milk reduced by around 10 %, with small productivity gains
Bromoform	Residue and occupational safety, ozone-layer concerns about the compound and wild-harvest sustainability are under review

Advantages#

The largest reductions available from any feed additive (Asparagopsis).
Fits the feed chain: delivered through compound feed, TMR or premix.
Carbon-credit and buyer-premium income can pay for the additive.
Essential-oil and tannin options are plant-based and familiar to organic farming.

Mode of action#

Bromoform blocks the cobamide-dependent methyl-transfer steps of methanogenesis in rumen archaea, so hydrogen is redirected to other fermentation products.
Essential oils change the rumen microbial community and fermentation pattern.
Tannins bind protein and reduce fibre fermentation by methanogen-associated protozoa.

Application#

System	Target	Method, timing and specifics
Feedlots	Max reduction	Asparagopsis in finishing rations, fed daily
Dairy (TMR)	Reduction + milk	Asparagopsis or essential-oil blend in TMR; monitor milk bromoform
Grazing	Delivery	Boluses/licks still in development; tannin-rich forages; breeding for low methane
All	Verification	Measure with GreenFeed or respiration chambers before claiming credits

Limitations#

Seaweed cultivation at scale is new; wild harvest is not sustainable.
Effects can fade when animals adapt or doses vary; stability of bromoform in stored product.
Safety questions (bromoform residues, worker exposure, thyroid effects in some trials) must be closed for regulators.
Grazing animals are hard to dose daily.

Enzymatic degumming (phospholipases) and enzymatic interesterification (immobilized lipases) of edible oils instead of acid–caustic chemical degumming and sodium-methoxide chemical interesterification

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: acid–caustic degumming, sodium-methoxide interesterification, partial hydrogenation · Scope: vegetable oil refining, specialty fats · Evidence: high

The chemical problem#

Crude oils contain phospholipids (“gums”) that must be removed. Chemical degumming and caustic neutralization use phosphoric acid and sodium hydroxide, create soapstock and salty wastewater, and lose neutral oil into the gums.
Solid fats for margarine and bakery were made by partial hydrogenation, which creates trans fats — now banned or limited in many countries (WHO REPLACE campaign).
The common replacement, chemical interesterification, uses sodium methoxide, a hazardous catalyst, and gives random fat structures.

Product overview#

Enzymatic degumming — phospholipase A1/A2 or C converts non-hydratable phospholipids into forms that wash out with water, or into diacylglycerol that stays in the oil → higher oil yield.
Enzymatic interesterification — immobilized sn-1,3-specific lipases (e.g. from Thermomyces lanuginosus) rearrange fatty acids to make trans-free hard stocks and specialty fats (cocoa-butter equivalents, infant-formula lipids).
Both enzyme types are made by industrial fermentation.

Active ingredient / Composition#

Phospholipases (PLA1, PLA2, PLC; sometimes combined), dosed in ppm of oil with water and pH control.
Immobilized lipase in packed-bed reactors; enzyme reused for many tonnes of oil.

Key facts#

Parameter	Value
Degumming yield	PLC and combined enzyme processes recover extra oil compared with chemical degumming (yield is the main economic driver)
Phosphorus	Enzymatic degumming reaches the low P levels needed for physical refining or biodiesel
Interesterification	Lipase reactors run continuously; no catalyst neutralization or bleaching for soap removal
Trans fats	Enzymatic interesterification + full hydrogenation or palm fractions → trans-free structured fats

Advantages#

Higher oil yield, less soapstock and wastewater.
Removes sodium methoxide and part of the caustic/acid handling from the plant.
Positional specificity of lipases gives functional fats chemical routes cannot make.
Supports trans-fat elimination rules.

Mode of action#

PLC splits phospholipids into diacylglycerol (stays in oil) and a water-soluble phosphate ester (removed).
PLA1/PLA2 remove one fatty acid → lysophospholipids that move into the water phase.
sn-1,3 lipases exchange fatty acids only at the outer positions of triglycerides → controlled structure.

Application#

Stage	Target	Method, timing and specifics
Soybean/rapeseed crush plants	Degumming	Enzymatic degumming after water degumming; then physical refining
Biodiesel feedstock prep	Low P	Enzymatic degumming to meet P specs (see EN03)
Margarine and shortening	Trans-free hard stock	Enzymatic interesterification of fully hydrogenated oil or palm stearin blends
Specialty fats	Structured lipids	Lipase-catalyzed acidolysis for cocoa-butter equivalents and infant-formula lipids

Limitations#

Enzyme cost and process control (pH, temperature, mixing) must be justified by yield gains.
Immobilized lipase is sensitive to oil quality (oxidation products, residual P poison it).
Does not replace bleaching and deodorization.
3-MCPD/glycidyl-ester formation in deodorization is a separate issue.

Assessment (hand-reviewed): Argentina: enzymatic degumming refines ~10% of soybean oil.

Enzymatic high-fructose syrup from starch instead of sucrose and acid hydrolysis

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: sucrose and acid-hydrolysed glucose · Scope: starch-based sweeteners · Evidence: high (USA)

The chemical problem#

Glucose syrups were long made by acid hydrolysis of starch: hot hydrochloric acid gives uncontrolled breakdown, bitter by-products and colour, and caps the achievable sweetness (glucose is less sweet than sucrose).
Sucrose from cane and beet was protected by quotas and tariffs, and its price swung with harvests — a costly input for beverage makers.

Product overview#

A chain of three enzymes turns starch into a sucrose-equivalent syrup: α-amylase (liquefaction), glucoamylase (saccharification to glucose) and glucose isomerase (xylose isomerase, immobilised in packed columns) converting part of the glucose to fructose. HFCS-42 comes straight off the column; HFCS-55 (beverages) is enriched by chromatography. In the EU the same product is called isoglucose.

Farm nitrate and phosphate runoff controlled by biology — denitrifying bioreactors, wetlands and algal uptake — instead of end-of-pipe chemical dosing

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: chemical end-of-pipe nutrient removal · Scope: tile-drained farmland · Evidence: high

The chemical problem#

Artificially drained farmland ships nitrate straight from the root zone to the stream — the classic dead-zone engine (Gulf of Mexico, Baltic, Lake Tai chlorophyll).
Phosphate arrives in pulses with erosion; catchments respond with ferric/alum dosing plants (W01’s chemicals again: sludge, acidity, cost per kg P removed).
The lost nitrogen was paid for twice: as fertilizer and as the waterworks’ nitrate-blending problem; every kg lost also carries N₂O climate weight.

Product overview#

Denitrifying bioreactors: a woodchip-filled trench at the tile-drain outlet — carbon-feeds bacteria that convert NO₃⁻ to N₂ gas. Passive, no inputs for ~15 years, ~30–50 % annual nitrate load removal at field scale (US Midwest programs, New Zealand).
Edge-of-field / treatment wetlands (E05 logic applied to farm runoff): settling + plant uptake + denitrification; also the P-catchment workhorse.
Microalgal nutrient recovery: algae ponds scrub N and P from drainage and manure lagoons — the nutrient becomes algae biomass (FI01 colours, FD02 feed ingredients) instead of a problem.
Upstream precision (root cause): FD01 phytase/amino-acid feeding and variable-rate N cut the load at the source — biology before the pipe.

Active ingredient / Composition#

Woodchip carbon (pine/poplar), 30–60 m³ per ha drained; hydraulic residence 4–8 h at peak flow.
Wetland plants (Phragmites, Typha), sediments as P sinks.
Microalgae (Chlorella, Spirulina, native polycultures) with CO₂ supplementation.

Key facts#

Parameter	Value
Class	Passive biological treatment (edge-of-field)
Nitrate removal	2–25 kg N/ha/yr bioreactor; wetlands more
Lifetime	Woodchip recharge every 10–20 years
Cost	Among the cheapest $/kg-N removed of any option

| Co-benefit | Wetland habitat; algae biomass as product |

Advantages#

No chemical deliveries, no sludge, no operator: the bioreactor is buried and passive.
Buys time for the agronomy to catch up (precision feeding, FD01; N-fixation, A35).
Algal routes close the loop: nutrient waste becomes feed/ingredient revenue.
Sits exactly where this index’s water-bioremediation vendors (112 active) sell engineering.

Mode of action#

Denitrifiers on woodchip surfaces oxidize the carbon and reduce NO₃⁻ → NO₂⁻ → N₂O → N₂ (the last step is why saturated, carbon-rich media matter).
Wetlands: sedimentation + sorption (P), nitrification/denitrification in soil-water gradients.
Algae assimilate NH₄⁺/NO₃⁻/PO₄³⁻ into biomass; harvesting exports the nutrient.

Application#

Site	Target	Method, timing and specifics
Tile-drained corn/soy or vegetable farm	Nitrate	Woodchip bioreactor at the outlet; size to drainage area; monitor flow+NO₃
Catchment / co-op	P + N	Multi-cell wetland on the main ditch; sediment management plan
Dairy lagoon / biogas digestate	N, P	Microalgal scrubber; biomass to feed (FD02) or soil amendment
Water utility	Source protection	Pay farms for edge-of-field biology — cheaper than nitrate blending at the works

Limitations#

Bioreactors mostly miss dissolved P (pair with wetlands/P-sorbent filters — some chemical).
Cold-season performance drops; design for spring melt accordingly.
Algal recovery needs land, light and harvesting energy — best in sunny regions (which this index has).
Root causes (over-fertilization) still need agronomy; edge-of-field biology is the safety net, not the license.

Feed enzymes (phytase) and fermentation amino acids instead of inorganic phosphate and excess crude protein

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: dicalcium phosphate, excess crude protein · Scope: pig & poultry nutrition · Evidence: high

The chemical problem#

Two-thirds of the phosphorus in grain and soybean meal is locked as phytate and ends up in manure. To compensate, nutritionists add dicalcium phosphate from mined rock phosphate — a finite resource with cadmium/fluoride impurities — and the unabsorbed P still runs off into rivers: eutrophication, algal blooms, fish kills (links: E06).
Feeding protein as “safety margin” means the excess N leaves as urea → ammonia air pollution and nitrates in water.
Rock phosphate is an import dependency for most countries in this index’s regions.

Product overview#

Phytase (since 1991 in feed): a fungal/bacterial enzyme that releases phytate P before it reaches the manure. Doses are measured in FTU/kg; modern “next-generation” phytases release more P at lower doses. Global adoption: the majority of pig and poultry feeds worldwide.
Fermentation amino acids (L-lysine, L-threonine, L-tryptophan, L-valine — made by Corynebacterium glutamicum/E. coli fermentation): let nutritionists formulate to exact amino-acid needs with less total protein, cutting N excretion 20–30 % while keeping or improving growth.
NSP enzymes (xylanase, β-glucanase) and proteases unlock energy and protein from fibrous vegetable meals, displacing added fat and over-formulated protein.

Together this is the largest quiet bioeconomy substitution in livestock: biology replacing a mined mineral and a pollution stream, one feed formula at a time.

Feed hygiene without formaldehyde — fermentation organic acids, inoculants and heat treatment

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: formaldehyde feed treatments · Scope: feed mills & farms · Evidence: high

The chemical problem#

Formaldehyde-based products (formalin + organic acid blends) are sprayed on soybean meal and compound feeds to kill Salmonella — a Group 1 carcinogen dosed in industrial halls, with residual-air and worker-exposure problems.
The EU re-approved formaldehyde for feed hygiene in 2018 only with strict occupational measures — a signal of where regulation is heading for CIS feed mills that still handle it casually.
Mold inhibitors of the chemical era (pure propionate from petro routes) complete the same picture.

Product overview#

Organic acid blends (formic, propionic, lactic, acetic, sorbic): the standard Salmonella/mold control in feed — today largely fermentation-derived (the same acid family as FI/food-ingredients). Free acids lower feed pH and pass into the animal gut (FD01 logic).
Heat treatment / pelleting at 85–92 °C: thermal kill step for high-challenge ingredients (the mill already owns the equipment).
Inoculants and protective cultures: silage inoculants (homo-/heterofermentative Lactobacillus) replace chemistry at the forage stage — the biggest volume use of biology in feed preservation.
Mill-hygiene SOPs + monitoring: diagnostics-driven, chemical-light decontamination (per the catalogue’s diagnose→threshold pattern: V-series).

Active ingredient / Composition#

Formic acid 85 %, propionic acid 99 %, blended salts (ammonium formate/propionate for less corrosion); dosed 3–10 kg/t feed depending on challenge.
Silage inoculants: ≥1×10⁵ CFU/g forage LAB (e.g. L. plantarum, L. buchneri for aerobic stability).
Medium-chain fatty acids (C8–C10) as gut-hygiene adjuncts.

Key facts#

Parameter	Value
Class	Fermentation acids + cultures + heat
Salmonella effect	1–2 log reductions in feed with acid programs (plus mill hygiene)

| Mold control | Propionate/sorbate at 0.2–0.5 % inhibits toxigenic molds (V11 link) | | Worker safety | Acids are corrosive but not carcinogenic — remove the aldehyde exposure |

Advantages#

Removes a Group 1 carcinogen from mill air and worker exposure — immediate occupational win.
Acids double as gut-hygiene/growth promoters (acidifying the stomach), partially replacing the antibiotic-growth-promoter era (V01 link).
Fermentation supply chain (BBCA/Jindan class producers) is domestic in exactly the regions of this index.
Inoculants replace chemistry at the farm’s own forage — the cheapest bio-substitution in the feed chain.

Mode of action#

Undissociated acids cross the bacterial membrane and dissociate inside, collapsing ΔpH (Salmonella, molds); formate/propionate also feed epithelial development in young animals.
LAB inoculants drive fast lactic fermentation, dropping pH before spoilers establish; L. buchneri converts lactate to acetate/propionate for aerobic stability at feed-out.
Heat: lethality kinetics (D-values) at 85–92 °C for enterics in the pellet matrix.

Application#

Site	Target	Method, timing and specifics
Feed mill	Salmonella in ingredients	Organic-acid dosing at reception + heat at pelletizer + mill hygiene monitoring
On-farm mixing	Mold/mycotoxin prevention	Propionate/sorbate in storage grains; dry matter discipline
Silage (dairy/beef)	Fermentation quality	Homofermentative inoculant at chopping; L. buchneri for long face-stability
Young-animal feeds	Gut hygiene	Acidifier blends in prestarter (synergy with FD01 amino-acid precision)

Limitations#

Acids corrode equipment (use salts/blends and stainless dosing); dose discipline matters.
Very high-challenge ingredients (post-outbreak) may still need heat — acids alone underdeliver there.
Inoculants cannot rescue poor silage practice (dry matter, compaction, speed).
Formaldehyde products remain legal-with-conditions in the EU and common in some regions — the substitution is regulatory + safety driven, not forced.

Assessment (hand-reviewed): Old practice ended by law: formaldehyde in feed became illegal in the EU (Reg. 2018/183); the share replaced by inoculants vs organic acids is not shown.

Fermentation (stainless and single-use bioreactors, solid-state reactors) and downstream equipment (centrifuges, filtration, spray and fluid-bed drying, formulation) for local production of enzymes, microbial products and fermentation ingredients instead of chemical-synthesis plants and imports

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: chemical-synthesis plants and imports for fermentation-made products · Scope: pilot to industrial, submerged and solid-state · Evidence: high

The chemical problem#

Almost every substitution in this catalogue ends in a fermentation tank: enzymes (FI07, FD01, I02), organic acids and platform chemicals (BR01), vitamins (FI04), microbial pesticides and inoculants (A-series, NU02), probiotics (V01).
Regions without fermentation capacity import these products or stay with the chemical route.
Capacity is the bottleneck: precision-fermentation and biologicals start-ups worldwide report shortages of pilot and demonstration-scale tanks.

Product overview#

Stainless-steel fermenters — 20 L pilot to 100+ m³ industrial; steam-sterilized; the standard for enzymes, acids and amino acids.
Single-use bioreactors — pre-sterilized plastic bags in a support vessel; low capital, no cleaning validation; established in biopharma, now used for cell culture, precision fermentation and pilot work.
Solid-state fermentation reactors — tray, packed-bed or rotating-drum reactors for fungal products (enzymes, conidia of biocontrol fungi).
Downstream processing — centrifugation, micro/ultrafiltration, chromatography, evaporation.
Drying and formulation — spray, fluid-bed and freeze drying; encapsulation; granulation — these decide shelf life of live products.
Process engineering / turnkey plants — ethanol, biogas and biorefinery plant builders.

Active ingredient / Composition#

Not applicable (equipment). Key specifications: working volume, sterility design, oxygen transfer (kLa), temperature/pH control, automation, materials (316L stainless, glass-lined, single-use films).

Key facts#

Parameter	Value
Single-use vs stainless	Single-use: lower capital and faster changeover; stainless: lower cost per kg at large, continuous scale
Solid-state fermentation	Lower water and energy use for fungal products; harder to scale and control than submerged
Drying	Spray drying is cheap but can kill live cultures; fluid-bed and freeze drying keep viability higher
Alternative	CDMOs offer capacity without owning equipment

Advantages#

Enables every fermentation-based substitution in the catalogue to be made locally.
Modular and single-use systems lower the entry ticket for new regional producers.
Equipment plus service (installation, validation, training) is a recurring revenue line.

Mode of action#

Bioreactors control the microbe’s environment (oxygen, temperature, pH, nutrients) to maximize product formation.
Downstream steps separate, concentrate and stabilize the product; formulation determines shelf life and field performance.

Application#

Buyer	Need	Equipment and specifics
Bio-input producers	Bacillus, Trichoderma, Bt	Stainless fermenters + solid-state units + drying/formulation line
Enzyme and feed-additive plants	Enzymes, probiotics	Industrial fermenters, ultrafiltration, spray/fluid-bed drying
Start-ups, universities	Pilot work	Single-use or small stainless pilot fermenters; or a CDMO
Ethanol/biogas investors	Turnkey plant	Process-engineering firms (EN01, EN02, BR01)

Limitations#

Capital-intensive at industrial scale; utilities (steam, chilled water, clean air) often the hidden cost.
Single-use plastics create waste.
Scale-up is a skill, not just equipment: many projects fail between pilot and industrial scale.
Equipment makers are concentrated in Europe, the USA, China and India; local service networks matter.

Evidence of displacement — D1: works, adoption not proven#

Assessment (hand-reviewed): Mismatch: bio-succinic acid at 49% of the market is biorefining evidence (BR01), not equipment.

Fermentation and algal food colours instead of azo dyes (tartrazine, sunset yellow) and titanium dioxide

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: azo dyes (E102/E110/E122/E124/E129), E171 · Scope: drinks, dairy, sweets, feeds · Evidence: high

The chemical problem#

Azo dyes (tartrazine E102, sunset yellow E110, azorubine E122, ponceau 4R E124, allura red E129) are coal-tar-chemistry descendants that triggered the Southampton study (McCann et al. 2007): mixtures increased hyperactivity in children. Since July 2010 the EU requires the warning label “may have an adverse effect on activity and attention in children” on foods containing them; EFSA re-evaluations cut several ADIs (sunset yellow from 2.5 to 1 mg/kg bw/day).
Titanium dioxide (E171) was suspended as a food additive in the EU in 2022 (Regulation (EU) 2022/63) over genotoxicity concerns that could not be ruled out.
Synthetic dyes carry impurity risks (benzidine-class traces from azo synthesis) and a label consumers increasingly reject.

Product overview#

The same colours nature uses, produced by fermentation or algae at industrial scale — often with a vitamin as a bonus:

Fermentation and plant-derived sweeteners instead of aspartame, saccharin and sucralose

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: aspartame, saccharin, sucralose, part of sugar · Scope: drinks, dairy, confectionery · Evidence: high

The chemical problem#

Aspartame was classified possibly carcinogenic (IARC Group 2B) in July 2023 — the most consumer-visible sweetener event in decades; JECFA kept the ADI, but labels now carry a story marketers don’t want.
Saccharin carries a century of ban history; sucralose persists through wastewater treatment and is measurable in rivers.
All three are synthetic molecules from chlorination/chemical synthesis chains — exactly the “coal-tar descendant” pattern of FI01’s azo dyes.

Product overview#

Steviol glycosides (stevia): extracted from Stevia rebaudiana; the better-tasting minor glycosides (Reb M, Reb D) are made by fermentation or enzymatic glucosylation — the precision-fermentation answer to stevia’s licorice off-note.
Monk fruit (Siraitia grosvenorii): mogrosides, natural high-potency; supply and cost limited.
Allulose: a rare sugar made by enzymatic epimerization of fructose; tastes and bakes like sugar at 0.4 kcal/g (US label-friendly; EU approval pending).
Erythritol and polyols: erythritol by yeast fermentation of glucose; sorbitol/maltitol/xylitol from bio-based sugars — bulk sweetness with dental/calic advantages.

Active ingredient / Composition#

Stevioside/rebaudiosides: diterpene glycosides, 200–400× sucrose sweetness; grades ≥95 % (REB-A 97, SG95).
Erythritol: C4 polyol, ~60–70 % sucrose sweetness, zero-calorie label in many jurisdictions.
Allulose: D-psicose; ~70 % sweetness, browns like sugar.

Class	Plant extract + fermentation/enzymatic sweeteners
Regulatory	Stevia E960, polyols E968/E965… approved in EU/EAEU; allulose US GRAS, EU pending
Dose vs sugar	Stevia: replace 100 % of sweetness; polyols also replace bulk/volume

| Formulation | Taste mods blend stevia+allulose/erythritol to flatten sweetener off-notes |

Advantages#

No IARC story on the label — the clean-label motive is doing to aspartame what the hyperactivity label did to azo dyes (FI01).
Fermentation-made Reb M/D remove the off-note that capped stevia’s penetration — enabling full sugar replacement in colas.
Zero/low calorie with dental benefits (polyols) — sugar-tax products reformulate this way already.
Feedstocks are glucose/stevia leaf chains — same sugar-belt industrial system as EN02/FI01.

Mode of action#

Biology: stevia leaf biosynthesis (UGT enzymes) or engineered yeast produce the glycosides; erythritol via Yarrowia/Torula osmophilic fermentation; allulose via D-tagatose-3-epimerase immobilized enzymes.
Physiology: sweet-receptor (T1R2/T1R3) agonism without metabolizable calories (glycosides excreted; erythritol absorbed and excreted unmetabolized).

Application#

Application	Target	Method, timing and specifics
Colas/soft drinks	Aspartame/acesulfame exit	Stevia (Reb M/D grades) + erythritol/allulose blend for mouthfeel
Dairy, yoghurt	Sugar reduction	Stevia + polyol; watch texture with milk protein interactions
Bakery	Sugar roles beyond sweetness	Allulose for browning; erythritol for bulk (watch cooling effect)
Tabletop sweetener	Retail switch	Stevia/monk-fruit sachets replacing aspartame sachets

Limitations#

Cost: Reb M/D and allulose still several× aspartame per sweetness unit.
Regional approvals differ (allulose EU; stevia leaf as novel food in some markets).
Taste: high-rate replacement still needs blend engineering; laxation limits for some polyols.
Sugar itself is the real target — sweeteners shift the problem rather than fix diets (honest scope note).

Fermentation cosmetic ingredients instead of shark-liver squalene, rooster-comb hyaluronic acid and animal collagen

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: shark squalene, rooster-comb HA, animal collagen · Scope: skin-care actives · Evidence: high (HA, squalane)

The chemical problem#

Squalene was classically rendered from deep-sea shark liver oil (livers up to a third of body weight). Shark species are slow to reproduce; conservation pressure (and EU deep-sea fishing restrictions) pushed the industry to plant and fermentation sources.
Hyaluronic acid (HA) was first commercialized from rooster combs — an animal by-product with traceability, certification (halal/kosher/vegan) and consistency problems.
Collagen from bovine/porcine hide/bone carries the same certification burden plus consumer-animal-welfare expectations in premium skincare.
These are not “toxic chemicals” — the problem class here is unsustainable animal sourcing, the cosmetic face of the same substitution logic the catalogue applies to hazard.

Product overview#

Sugarcane squalane (squalene hydrogenated to stable squalane): farnesene from yeast fermentation of Brazilian sugarcane → squalene → squalane. Now the mainstream source; identical molecule to shark-derived (C₃₀ isoprenoid).
Fermentation HA: Streptococcus zooepidemicus/equi fermentation → sodium hyaluronate at food/cosmetic/pharma grades. China’s fermentation HA cluster supplies the majority of the world market — Bloomage and Baotou Dongbao are among the largest producers globally (both in this index).
Collagen-equivalents: yeast-fermented recombinant collagen fragments/peptides and “collagen-boosting” signal peptides (commercial, e.g. in Chinese and Korean premium skincare); full-length recombinant collagen is scaling but not yet a complete hide-collagen replacement.

Active ingredient / Composition#

Squalane: C₃₀H₆₂, saturated hydrocarbon, exceptional oxidative stability, skin-identical emollient (2–30 % of formula).
Sodium hyaluronate: glycosaminoglycan, MW 10 kDa–2 MDa; low MW penetrates, high MW films.
Recombinant collagen peptides/fragments with declared sequences; hydrolyzed collagen (animal) remains the reference for full structure.

Key facts#

Parameter	Value
Class	Fermentation-derived cosmetic actives
Source organisms	Saccharomyces (squalene route), Streptococcus (HA), yeast/E. coli (collagen fragments)
Regulatory	Cosmetic ingredient dossiers (EU CPNP/SCCS; in Russia: EAEU technical regulation TR CU 009/2011)
Certifications	Vegan/halal/kosher-friendly vs animal sourcing
Market share	Fermentation HA > majority of global supply; sugarcane squalane mainstream

Advantages#

No sharks, no combs, no hides — traceability and certification problems disappear with the animal.
Fermenter-sited supply: price and quality stability, no fishery volatility.
Molecular identity with the animal version (squalane) — no consumer-perceptible trade-off.
Same sugar feedstocks as the ethanol/food-ingredient clusters of this index (EN02, FI01).

Mode of action#

Biology: engineered yeast mevalonate pathway → farnesene → farnesene dimerization to squalene; Streptococcus HA synthase polymerizes UDP-glucuronate + UDP-N-acetylglucosamine to the HA chain; secreted recombinant collagen fragments from yeast.
Skin: squalane as biomimetic emollient; HA water-binding (up to 1,000× its weight) and barrier film; collagen peptides as signalling/moisturizing agents.

Application#

Product type	Target	Method, timing and specifics
Facial serums/oils	Emollient	Squalane 2–30 % (fermentation-sourced per INCI supplier claim)
Hydrating serums/creams	Moisturizer actives	HA multi-MW blends 0.1–2 %
Premium/labeled lines	Vegan/halal positioning	Fermentation HA + recombinant peptides instead of animal collagen
Supplier qualification	Claims	Ask for source dossiers (fermentation vs animal) — both carry the same INCI, so provenance is contractual

Limitations#

INCI names don’t reveal the source — greenwashing risk; verify supplier dossiers.
Full-length recombinant collagen is not yet a full replacement for animal collagen in structural uses (medical-grade especially).
Fermentation HA capacity is concentrated in a few producers — supply concentration risk.
Cost of recombinant peptides remains premium-tier.

Fermentation- and sugar-derived platform chemicals (lactic acid, succinic acid, 1,3-propanediol, 1,4-butanediol, bio-ethylene and bio-MEG) instead of the same building blocks made from oil and gas

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: petrochemical routes to the same building blocks · Scope: polymers, solvents, food/feed acids · Evidence: high (lactic, PDO, bio-ethylene), medium (succinic, BDO economics)

The chemical problem#

Most bulk chemicals and plastics start from naphtha or natural gas, with process emissions and hazardous intermediates (acrolein, ethylene oxide, maleic anhydride).
Brand owners and regulators want bio-based content (EU bio-based product standards, carbon-footprint labelling), and some routes compete on cost when oil is expensive.
The catalogue already covers what is made from these building blocks (PK04 bioplastics, I01 bio-solvents, I02 biocatalysis). This article covers the platform molecules themselves.

Product overview#

Lactic acid — fermentation of glucose or sucrose by lactic-acid bacteria; feedstock for PLA, lactate solvents, food acids. Fermentation is the main industrial route.
1,3-Propanediol (PDO) — engineered E. coli fermentation of glucose; used in PTT fibres, cosmetics, de-icers.
Succinic acid — bacterial/yeast fermentation; for PBS bioplastics, polyurethanes, de-icers.
1,4-Butanediol (BDO) — engineered E. coli directly from sugar; for PBT, spandex precursors, solvents.
Bio-ethylene and bio-MEG — dehydration of fermentation ethanol (sugarcane, molasses) → bio-polyethylene and bio-PET (MEG part).
Other platform molecules on the US DOE “top” list: levulinic acid, furans (FDCA), sorbitol, glycerol derivatives.

Active ingredient / Composition#

Feedstock: cane sugar, molasses, corn/cassava starch glucose; second-generation lignocellulosic sugars (emerging).
Production organisms: Lactobacillus/Bacillus coagulans (lactic), engineered E. coli (PDO, BDO), Actinobacillus/Basfia/yeast (succinic).
Downstream: precipitation, electrodialysis, distillation, crystallization.

Key facts#

Molecule	Status	Main use
Lactic acid	Fermentation is the dominant industrial route	PLA, food, solvents
1,3-PDO	Commercial bio-route widely used	PTT fibres, personal care
Bio-ethylene / bio-MEG	Commercial from sugarcane and molasses ethanol	Bio-PE, bio-PET
Succinic acid, BDO	Commercial plants exist; profitability depends on oil price	PBS, PBT, PU

Advantages#

Same molecule, so it drops straight into existing polymer and chemical plants.
Lower fossil carbon; often fewer hazardous intermediates.
Creates value for sugar, starch and residue streams (link to BR02).
Fermentation plants are built in sugar- and starch-rich regions (Brazil, Thailand, India, China).

Mode of action#

Microbes convert sugars through engineered or natural pathways (glycolysis → pyruvate → lactate; reductive TCA branch → succinate; engineered pathways → BDO).
Ethanol dehydration over solid acid catalysts gives ethylene; oxidation and hydration give MEG.

Application#

Buyer	Target	Method, timing and specifics
PLA and lactate-solvent makers	Lactic acid	Long-term lactic acid supply from fermentation plants
Fibre and polyester producers	PDO, bio-MEG	Drop-in replacement in PTT/PET recipes
Bioplastic compounders	Succinic acid, BDO	PBS/PBAT and PBT production (PK04)
Packaging brand owners	Bio-based content	Bio-PE and bio-PET with mass-balance or direct bio-content certification

Limitations#

Cost: many routes are only competitive at high oil prices or with green premiums.
Feedstock competition with food (sugar, starch) unless residues are used.
Bio-based ≠ biodegradable: bio-PE and bio-PET are durable plastics.
Several fermentation BDO and succinic plants were idled when oil prices fell — market risk is real.

Assessment (hand-reviewed): Minority and conflicting: bio-succinic acid ~49% of the market in 2013/14 vs 3% in 2011; 1,3-propanediol production shared between fermentation (CovationBio, METEX) and petrochemical routes (peer-reviewed; market-research claims of ~56–60% bio-based not counted).

Fermentation-produced chymosin instead of calf rennet in cheesemaking

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: calf rennet · Scope: cheesemaking coagulants · Evidence: high

The chemical problem#

Traditional calf rennet is chymosin extracted from slaughtered veal calves’ stomachs: supply tied to veal economics (dairy cows don’t slaughter themselves for cheese), price volatile, and ethically/religiously constrained (vegetarian, halal and kosher label issues).
Older substitutes — porcine pepsin, microbial coagulants from Mucor — carried bitterness, yield loss and their own animal/acceptability limits.
Cheesemaking is coagulant-critical: a weak substitute chemistry costs yield and texture, which is why this substitution had to be exact, not approximate.

Product overview#

Fermentation-produced chymosin (FPC): the calf chymosin gene expressed in Kluyveromyces lactis or Aspergillus niger fermenters — the identical enzyme, unlimited supply, no animal input. Approved in the USA (1990, first FDA approval of a product from an engineered organism for food) and the EU; today the majority of global cheese (estimates commonly cite ~70–80 %+ of volume in the West) is made with FPC. Variants: bovine, camel (higher clotting activity — better for some milks) and optimized pH-thermal profiles.

Fermentation-produced vitamins (B2, B12, C routes) instead of multi-step chemical synthesis

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: chemical vitamin synthesis routes · Scope: food & feed vitamins · Evidence: high

The chemical problem#

Vitamin B12 has ~70 chiral centers and defied total synthesis at commercial scale: the “chemical” route never existed — every gram on earth is microbial.
Vitamin C’s Reichstein process (1933) runs glucose through five chemical steps (strong acids, solvents, high energy) plus one fermentation — a 50 %+ cumulative-yield chain still running in places.
Riboflavin (B2) chemical synthesis (six steps from D-ribose) was abandoned in the 2000s: Ashbya gossypii fermentation overran it on cost and environmental profile.
For food and feed labels, “produced by fermentation” is also simply a better story than “produced by the Reichstein process”.

Product overview#

Riboflavin (B2): Ashbya gossypii (filamentous fungus) or Bacillus subtilis — over 80–90 % of world production is microbial; the grand proof of this article’s thesis.
Cobalamin (B12): Propionibacterium (cheese-chain organism) or Pseudomonas denitrificans fermentation — the only source; used in food fortification, feed and supplements.
Vitamin C: modern two-step biocatalytic routes (sorbose → 2-KLG by engineered Ketogulonicigenium/Gluconobacter) collapsing the Reichstein chain; Chinese producers (this index’s cluster) run the world supply.
Provitamin A / carotenoids: Blakeslea trispora fungal beta-carotene, algal Dunaliella (FI01) — natural-route vitamins with dual colour function.

Active ingredient / Composition#

Riboflavin ≥96 % feed grade, 80 % spray-dried; B12 as cyanocobalamin 1 % premix (pure crystals are dosed in micrograms); vitamin C as L-ascorbic acid/phosphates.

Key facts#

Parameter	Value
Class	Fermentation vitamins
B2	Majority microbial since ~2000s
B12	100 % microbial (no chemical route ever commercial)
Vitamin C	Two-step biocatalysis displacing 5-step chemical chain

| Feed use | Vitamins are ~2–5 % of premix cost — security of supply matters more than cents |

Advantages#

Lower energy, fewer solvents, fewer hazardous steps than the chemical chains they replaced.
Single fermenter plant vs multi-step chemical train → CAPEX and waste advantages (why the switch happened at all — economics, not regulation).
Local supply possible anywhere with a sugar stream (EN02/FI-cluster logic); resilient to trade shocks.
Same molecules, same bioactivity — zero reformulation.

Mode of action#

Biology: overproducing production strains (classical mutagenesis historically, now engineered pathways); vitamins accumulate in broth and are extracted/crystallized.
2-KLG route: D-sorbitol → L-sorbose (Gluconobacter) → 2-KLG (engineered Ketogulonicigenium) → ascorbic acid (one mild chemical lactonization).

Application#

Use	Target	Method, timing and specifics
Food fortification	B2, B12, C	Fermentation-grade vitamins; label as usual (identical molecules)
Feed premix	B2, B12, provitamin A	Source from fermentation producers; audit supply continuity
Clean-label products	“Fermented” claim	Provitamin A algal/fungal powders (colour + vitamin dual function)
Supply strategy	Resilience	Dual-source between the Asian fermentation majors in this index

Limitations#

Vitamin C’s final lactonization is still a (mild) chemical step — “fully biological” claims overreach.
Fermentation economics need scale; niche vitamin formats stay chemical.
B12 yield improvements are incremental and strain-locked (licensing matters).
Not every vitamin has a competitive bio route (vitamin D3 photochemistry remains photochemistry).

Evidence of displacement — D3: proven displacement at scale#

Assessment (hand-reviewed): Global: two-step fermentation replaced the Reichstein process; its Chinese users make >80% of world vitamin C.

Fish louse (Argulus) control in ponds and lakes with egg-laying substrate boards, pond drying/liming and biological management — instead of organophosphate treatments

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: organophosphate and pyrethroid treatments of pond water · Species: pond fish · Evidence: medium

The chemical problem#

Branchiuran fish lice (Argulus foliaceus, A. coregoni, A. japonicus) and anchor worms (Lernaea) damage skin and gills, cause secondary infections and mortality in pond carp and trout, and hurt recreational fisheries. Traditional control uses organophosphates (trichlorfon, dichlorvos) or pyrethroids poured into the ponds. These kill zooplankton and aquatic insects (the carp’s natural food base, and important for pond ecology), are neurotoxic, and in many countries are no longer authorized for aquaculture.

Fish vaccination (plus biosecurity and probiotics) instead of prophylactic/metaphylactic antibiotics in finfish aquaculture

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: routine antibiotics in medicated fish feed · Species: farmed fish · Evidence: high

The chemical problem#

Medicated feed releases a large part of the antibiotic directly into water and sediment (uneaten feed and faeces), which selects resistant bacteria in the environment. Large amounts of antibiotics, often not tracked, are used in aquaculture in Asia and Latin America (for example, heavy use in Chilean salmon farming against Piscirickettsia salmonis). Residues of banned drugs (chloramphenicol, nitrofurans) are regularly found in imported fish and shrimp by EU border controls.

Fly control in livestock barns with parasitoid wasps (Spalangia, Muscidifurax), Beauveria bassiana, predatory beetles and manure management

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: insecticide space sprays, wall sprays, neonicotinoid baits and feed-through larvicides · Species: all housed livestock · Evidence: medium–high

The chemical problem#

House flies (Musca domestica) and stable flies (Stomoxys calcitrans) spread pathogens (Salmonella, E. coli, Campylobacter, mastitis bacteria) and cause stress and lower milk yield and weight gain. House flies have developed resistance to almost every insecticide class (pyrethroids, OPs, neonicotinoids, cyromazine), sometimes within a few seasons. Chemical programs fail, and the dose and frequency escalate. Neonicotinoid fly baits end up in manure spread on fields. Dichlorvos is banned in the EU.

Food and market organic waste treated by black soldier fly (BSF) larvae, composting and bokashi fermentation instead of landfilling, open dumping and incineration of wet waste

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: landfill and open dumping of organics · Scope: municipal, market and agro-industrial organic waste · Evidence: high

The chemical problem#

Organic waste makes up about half of municipal waste in low- and middle-income countries; most of it is dumped or landfilled.
In landfills it decomposes without oxygen → methane and acidic leachate; open dumps breed flies and rats and often burn.
Incinerating wet organics wastes energy and needs auxiliary fuel.

Product overview#

Black soldier fly (BSF) larvae — larvae eat source-separated organic waste in 10–14 days, reduce its mass by roughly half or more, and produce protein/fat for feed (see FD02) and frass fertilizer (NU03).
Composting — windrow, in-vessel or aerated static pile, producing a quality-assured soil improver.
Bokashi — lactic-acid fermentation of food waste with inoculated bran; pre-treats waste at household and canteen scale before soil burial or composting.
Anaerobic digestion of food waste — covered in EN04.

Active ingredient / Composition#

BSF: Hermetia illucens larvae; feeding rates around 100 mg waste per larva per day in optimized systems.
Bokashi bran: lactic-acid bacteria, yeasts and phototrophic bacteria on a bran carrier.
Compost: mixed microbial succession (mesophilic → thermophilic → maturation).

Key facts#

Parameter	Value
BSF waste reduction	Typically 40–80 % dry-matter reduction depending on substrate
BSF greenhouse balance	LCA of a BSF facility: global-warming potential several times lower than open windrow composting of the same biowaste
Feedstock	Protein and fat-rich food waste gives faster larval growth; fibrous waste slower
Regulation	EU: insects may be fed only “feed-grade” substrates (no catering waste or manure for feed insects); rules are looser in many Asian and African countries — check before selling larvae as feed

Advantages#

Turns a disposal cost into two products: insect protein and fertilizer.
Short processing time (2 weeks) and small footprint compared with composting.
Works at decentralized scale (markets, canteens, cities without landfill space).
Cuts landfill methane and leachate at the source.

Mode of action#

BSF larvae and their gut microbes digest proteins, fats and carbohydrates; larval activity also aerates the substrate and suppresses pathogens and house-fly breeding.
Composting microbes mineralize organics; thermophilic phase (>55 °C) sanitizes.
Bokashi lowers pH by lactic fermentation, preserving the waste and limiting odour until it is buried or composted.

Application#

Situation	Target	Method, timing and specifics
City markets, food processors	Volume reduction, protein	BSF facility with source-separated organics; frass to farms
Households, canteens	Odour-free storage	Bokashi buckets; finish in soil or compost
Municipal green and food waste	Soil improver	Windrow or in-vessel composting to a quality standard
Wet waste with energy demand	Gas	Anaerobic digestion (EN04), digestate to NU03

Limitations#

Needs source separation; plastics and glass contaminate the outputs.
Feed-safety law limits which wastes may feed insects destined for animal feed.
BSF needs stable temperature (25–35 °C) and moisture management.
Market for frass and larvae must be built; prices vary.

Forest defoliator control (Siberian silk moth, spongy/gypsy moth, nun moth, pine moths) with Bt kurstaki, nucleopolyhedrovirus (NPV) and pheromone mating disruption — instead of aerial chemical insecticides

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: aerial chemical insecticides over forests · Scope: forest protection · Evidence: high

The chemical problem#

Outbreaks of defoliating caterpillars can strip millions of hectares. The Siberian silk moth outbreaks in Krasnoyarsk, Tomsk, Irkutsk and Yakutia have killed dark-coniferous taiga over huge areas, and are expanding north with warming. Aerial spraying with pyrethroids or diflubenzuron over forests and streams kills non-target insects, and the parasitoids and diseases that naturally collapse outbreaks.

Formaldehyde-free wood-based panels (plywood, particleboard, MDF) with bio-based adhesives — soy-protein, lignin, tannin and other bio-adhesives — instead of urea-formaldehyde (UF), melamine-UF and phenol-formaldehyde resins

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: urea-formaldehyde and related resins · Scope: wood panels and furniture · Evidence: high for plywood

The chemical problem#

Most interior wood panels are bonded with urea-formaldehyde, which releases formaldehyde into indoor air for months to years. Formaldehyde is an IARC Group 1 carcinogen and irritates the eyes and airways, and children are especially exposed at home and school. The EU limits formaldehyde emissions from wood-based products (from August 2026, Regulation (EU) 2023/1464), and the US has the CARB/TSCA Title VI limits. Russia is one of the largest plywood and particleboard exporters, so it is directly affected.

Garden, allotment and lawn pest control with beneficial nematodes — Phasmarhabditis against slugs, Steinernema/Heterorhabditis against vine weevil, chafer grubs, leatherjackets — instead of metaldehyde pellets and soil insecticides

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: metaldehyde and methiocarb slug pellets, garden soil insecticides · Scope: gardens, turf, nurseries · Evidence: high

The chemical problem#

Metaldehyde slug pellets were among the most widely used garden and farm pesticides. Metaldehyde reaches rivers and reservoirs and is hard to remove in drinking-water treatment, which is why UK water companies regularly exceeded the EU limit of 0.1 µg/L. It poisons dogs, hedgehogs and wildlife. Great Britain banned outdoor use from 31 March 2022. Methiocarb was not renewed in the EU (2020). Gardeners also use neonicotinoid and pyrethroid granules against soil grubs, which harms soil life and pollinators.

Gas-fermented single-cell protein (methane, CO2 and industrial off-gas) instead of fishmeal and imported protein concentrates in feed

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: a share of fishmeal and imported protein concentrates · Scope: aquafeed, pig, poultry, petfood · Evidence: medium-high (commercial, scaling)

The chemical problem#

Fishmeal comes from reduction fisheries (anchoveta, sandeel and others): roughly a fifth of the world’s wild catch is ground into meal and oil, a capped and climate-sensitive supply that competes with direct human food use.
Soy and rapeseed protein concentrates tie feed to land conversion, long import chains and volatile prices; the 2020-2022 spike hit import-dependent regions (much of Africa and the Middle East) directly in the feed cost.
Both routes fix protein where the feedstock is - coastal Peru, the Amazon frontier, the Black Sea - while the animals are elsewhere. A fermentation route decouples feed protein from geography entirely.

Product overview#

Gas fermentation grows protein-rich microbes on one-carbon feedstocks that would otherwise be vented or flared:

Genomic selection in dairy cattle breeding instead of progeny testing

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: progeny testing of AI bulls · Scope: dairy and livestock breeding · Evidence: high

The old process#

Until about 2009, an AI bull was proven by progeny testing: hundreds of daughters had to calve and complete a lactation before his breeding value was known — five years or more and a large cost per bull, with only a few bulls selected each year.
Slow cycles made it hard to select for low-heritability traits such as fertility, health and disease resistance.

Product overview#

Genomic selection predicts an animal’s breeding value from tens of thousands of DNA markers (SNP chips) using a reference population of genotyped, phenotyped animals (Meuwissen, Hayes and Goddard, 2001). US genomic evaluations for Holsteins became official in 2009. Breeding companies now market young genomic bulls directly, and farms genotype heifers to choose replacements.

Glutamate and MSG by bacterial fermentation instead of protein hydrolysis and chemical synthesis

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: acid hydrolysis of gluten and soy, chemical synthesis · Scope: glutamate/MSG and amino acids · Evidence: high

The chemical problem#

From 1909 (Ajinomoto) glutamate was made by boiling wheat gluten or soy protein in hydrochloric acid and crystallising glutamate from the hydrolysate: a lot of protein and acid per kilogram, with by-products to dispose of.
In the 1960s a chemical synthesis from acrylonitrile was run in Japan; it gave a racemic mixture that had to be resolved to the taste-active L-form and was abandoned in 1973.

Product overview#

In 1956 Kinoshita and colleagues (Kyowa Hakko) isolated Corynebacterium glutamicum, which excretes L-glutamate under biotin limitation. Fermentation from sugar quickly displaced both older routes. The same organism and process family now make lysine, threonine and other feed amino acids (FD01).

Grafting onto resistant rootstocks, biological/anaerobic soil disinfestation and biofumigation, and soilless (substrate and hydroponic) culture instead of methyl bromide and chemical soil fumigants

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: methyl bromide and chemical soil fumigants · Scope: greenhouse and field vegetables, strawberries, flowers · Evidence: high

The chemical problem#

Intensive greenhouse soils accumulate soilborne pathogens (Fusarium, Verticillium, Phytophthora), root-knot nematodes and weeds.
Methyl bromide was the standard soil fumigant until its phase-out under the Montreal Protocol (developed countries 2005, developing countries 2015) because it depletes the ozone layer.
Many growers switched to other chemical fumigants (metam, 1,3-D, chloropicrin), which are toxic and increasingly restricted.

Product overview#

Grafting onto resistant rootstocks — tomato, eggplant, pepper, cucumber, melon and watermelon scions grafted onto vigorous, disease- and nematode-resistant rootstocks.
Soilless culture — growing in coir, rock wool or other substrates, or hydroponics, removes the soil and its pathogens altogether (substrates: see CE01).
Biological / anaerobic soil disinfestation (BSD/ASD) — incorporating fresh organic matter, irrigating and covering with plastic film → anaerobic microbial activity kills pathogens.
Biofumigation — incorporating Brassica green manures (mustard) that release isothiocyanates.
Solarization (physical) and biological control agents (Trichoderma, Bacillus) as complements.

Active ingredient / Composition#

Rootstocks: interspecific tomato hybrids, Solanum torvum (eggplant), Cucurbita (cucurbits), Lagenaria.
ASD: fresh organic amendment (grass, rice bran, molasses) + water + gas-tight film for 3–6 weeks.
Biofumigation: high-glucosinolate mustard incorporated at flowering.

Key facts#

Parameter	Value
Italy	Phased out methyl bromide in protected crops largely through grafting, soilless culture, solarization and less toxic chemicals
Grafting	Widespread in East Asia and the Mediterranean; automated grafting in large nurseries
ASD	Field trials show strong suppression of several soilborne pathogens comparable to chemical treatment
Regulation	Montreal Protocol (methyl bromide); EU non-approval of 1,3-D and chloropicrin; national limits on metam

Advantages#

No fumigant exposure for workers and neighbours; no ozone or groundwater risk.
Grafted plants are often more vigorous and yield more.
Soilless culture enables water and nutrient recirculation.
ASD and biofumigation add organic matter.

Mode of action#

Resistant rootstocks carry resistance genes (e.g. Mi for root-knot nematodes, Fusarium resistance) and greater vigour.
ASD: anaerobic decomposition produces organic acids, low redox and toxic volatiles that kill pathogens.
Soilless culture breaks the soilborne disease cycle; disinfection of recirculating solution (slow sand filters, UV) prevents spread.

Application#

Situation	Target	Method, timing and specifics
Greenhouse tomato/cucumber	Fusarium, nematodes	Grafted transplants from specialized nurseries
High-tech greenhouses	All soilborne disease	Substrate culture on coir slabs; recirculation with slow sand filters
Field strawberries, vegetables	Soil disinfestation	ASD before planting; biofumigation in rotation
Nurseries	Clean media	Pasteurized or peat-free substrates (CE01) instead of soil fumigation

Limitations#

Grafted plants cost more; rootstock–scion compatibility must be tested.
Soilless culture needs capital, plastic substrates or slabs and technical skill.
ASD needs heat, organic material and 3–6 weeks of field time.
Some open-field crops still lack a full alternative.

Assessment (hand-reviewed): Old process eliminated (>99.8% of non-QPS methyl bromide phased out), but alternatives include chemical fumigants — the bio share is not shown.

Grease- and water-resistant food packaging without PFAS — dense molded fibre, glassine/high-density paper, and bio-based barrier coatings (chitosan, alginate, starch, proteins, plant waxes, PHA dispersions)

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: PFAS grease-proofing agents in paper and molded fibre · Scope: food packaging · Evidence: high for the hazard

The chemical problem#

Fluorinated compounds make paper and plant-fibre packaging resistant to grease and water. US testing found fluorine in about 46 % of food-contact papers and 20 % of paperboard samples (Schaider et al. 2017). PFAS migrate into food, persist forever, and contaminate compost and soil. Denmark banned PFAS in paper and board food-contact materials in 2020. Several US states banned PFAS in food packaging, and the EU Packaging and Packaging Waste Regulation (2025) restricts PFAS in food-contact packaging. IARC classified PFOA as carcinogenic to humans (Group 1) in 2023.

Hatchery and livestock-house disinfection without formaldehyde — hydrogen peroxide / peracetic acid, UV-C, and probiotic (Bacillus-based) cleaning to rebuild a beneficial surface microbiome

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: formaldehyde fumigation and formalin baths · Species: poultry, pigs, cattle · Evidence: medium–high

The chemical problem#

Formaldehyde fumigation (formalin + KMnO₄) is still common in hatcheries in Russia, the CIS, Asia and Africa: for hatching eggs, incubators and hatchers during hatching. Formaldehyde is classified by the IARC as a Group 1 human carcinogen. Exposure of chicks during hatching damages the tracheal epithelium (and increases respiratory disease). Workers are exposed to irritant and carcinogenic vapour. In the EU, formaldehyde use is increasingly restricted (occupational exposure limits and biocide regulation). In dairy farming, formalin foot-baths against digital dermatitis expose workers and pollute slurry.

Honeybee Varroa control with organic acids (oxalic, formic, lactic), thymol, brood interruption, drone-brood removal and Varroa-resistant bees (VSH, Primorsky/Russian bees)

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: amitraz, coumaphos, tau-fluvalinate and flumethrin in hives · Species: honeybees · Evidence: high

The chemical problem#

Varroa destructor and the viruses it transmits (especially deformed wing virus) are the main cause of colony losses worldwide. Beekeepers rely heavily on synthetic acaricides. The lipophilic ones (tau-fluvalinate, coumaphos, flumethrin) accumulate in beeswax for years. A US survey found up to 121 different pesticides in hive samples, with fluvalinate and coumaphos the most frequent. Recycled wax spreads the residues. Varroa resistance to pyrethroids and coumaphos is widespread, and amitraz resistance is now documented in the USA and Europe. Amitraz degradation products are found in honey. Where no legal product works, some beekeepers use agricultural acaricides illegally.

Household and institutional cleaning without triclosan, excess quaternary ammonium compounds (QACs) and routine chlorine — plain soap, enzyme-based detergents and probiotic (Bacillus) cleaners

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: triclosan and triclocarban antibacterial soaps, routine disinfectant sprays and wipes, routine bleach · Scope: households and institutions · Evidence: high

The chemical problem#

Triclosan was in soaps, toothpaste and textiles. In 2016 the US FDA banned triclosan, triclocarban and 17 other antibacterial ingredients in consumer hand and body washes, because manufacturers could not show they are better than plain soap and safe for long-term use. The EU does not approve triclosan for most biocidal product types. It persists in water and sediments.
QACs (benzalkonium chloride, didecyldimethylammonium chloride) use exploded during COVID-19. They are linked to occupational asthma and dermatitis, and to bacterial tolerance and co-selection of antibiotic resistance. They are found in wastewater, sludge and household dust.
Routine bleach use at home is associated with respiratory problems, and poisonings when mixed with other cleaners.

Product overview#

Plain soap and water: removes microbes mechanically. Handwashing with plain soap is as effective as antibacterial soap in community settings.
Enzyme-based detergents: proteases, amylases, lipases and cellulases made by fermentation (with Bacillus and fungal production strains) remove stains at 20–40 °C instead of 60–90 °C, which saves energy, and replace harsh chemistry. They are readily biodegradable.
Probiotic cleaning: cleaners containing spores of harmless Bacillus (B. subtilis, B. pumilus, B. megaterium) colonize surfaces and outcompete pathogens. An Italian multicentre hospital study (PCHS) found fewer surface pathogens, less AMR, and a reduction of healthcare-associated infections of about 52 %.
Bio-based surfactants: alkyl polyglucosides (sugar + plant fatty alcohols), sophorolipids and rhamnolipids (microbial biosurfactants).
Targeted disinfection only where needed (outbreaks, raw meat contact, sick household members).

Active ingredient / Composition#

Soap (fatty acid salts), enzymes (protease, amylase, lipase, mannanase), Bacillus spores (about 10⁷–10⁸ CFU/mL in concentrate), alkyl polyglucosides, sophorolipids, citric acid.

Industrial biocatalysis (enzymes and whole cells) — e.g. nitrile hydratase for acrylamide, engineered transaminase for sitagliptin, enzymatic antibiotic side-chain processes — instead of heavy-metal catalysts, high-pressure hydrogenation and multistep chemistry with toxic reagents

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: heavy-metal catalysis and harsh multistep chemistry · Scope: chemical and pharmaceutical industries · Evidence: high

The chemical problem#

Classical chemical processes often need heavy-metal catalysts, extreme temperatures and pressures, chlorinated solvents and toxic reagents, and they produce large amounts of waste per kilogram of product. This is especially true in pharmaceuticals, where it is common to generate 25–100 kg of waste per kg of product.

Insect meal, single-cell protein and algal ingredients instead of fishmeal and soybean meal in feed

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: fishmeal, (partly) soybean meal · Scope: aquafeed, petfood, pig/poultry · Evidence: high (commercial), partial share

The chemical problem#

Fishmeal: aquaculture and pig/poultry feeds draw on reduction fisheries (Peruvian anchoveta etc.). Roughly a fifth of the world’s wild catch is ground into meal and oil — a capped, volatile, climate-sensitive supply (El Niño years) that competes with human food use.
Soybean meal: the protein workhorse, but tied to land conversion in South America, long supply chains, antinutritional factors (trypsin inhibitors, oligosaccharides), and — in several producing countries — formaldehyde treatment against Salmonella, a carcinogen handled in feed plants.
For import-dependent regions (much of Africa/ME), both are foreign-currency line items; price spikes (2020–2022) hit feed costs directly.

Product overview#

Black soldier fly (BSF, Hermetia illucans) larvae: food/agro waste → larvae → defatted meal (55–60 % protein) + oil (lauric, antimicrobial-adjacent) + frass fertilizer. EU-approved in aquafeed (2017), pig/poultry (2021); commercial plants from Vietnam to Kenya to Latin America.
Mealworm (Tenebrio) for petfood and premium segments (EU approved 2023 for pig/poultry as PAP).
Single-cell protein (SCP): bacteria/methanotrophs on methane or natural gas → protein biomass (String Bio-type); fungi/yeast on sugars or residues (Changjin Bio-type). No land, tiny water footprint, fermenter-sited anywhere.
Microalgae (Spirulina, Chlorella, schizochytrium oil): protein + omega-3 DHA to replace fish oil fraction (also feeds FI01’s colour story).

Active ingredient / Composition#

Insect meal: crude protein 50–70 % (defatted), fat 5–15 %, chitin 4–8 % (prebiotic side-effect); BSF oil: C12 lauric ~30–40 %.
SCP: crude protein 65–77 %, balanced amino acids, nucleic acids (processing limit for some species).
Algae: protein 50–70 % (Spirulina dry), DHA-rich oils (schizochytrium).

Key facts#

Parameter	Value
Class	Insect biomass / microbial protein / microalgae
Feed-in	Agro-food waste, side streams, methane, sugars
Land & water	Orders of magnitude below soy per tonne protein
Biosecurity	Only authorized substrates (EU: no manure/catering waste for feed insects)
Regulatory	EU: insects as PAP in aqua/pig/poultry; in Russia: expert review regime — check current rules
Co-products	Insect oil, chitin, frass fertilizer; SCP: single amino-acid streams

Advantages#

Decouples feed protein from oceans and from deforestation — waste stream in, feed out (circular bioeconomy definition).
Local production in any climate: fermenters and larvae farms sit next to food mills, cities, breweries.
Better digestibility than untreated soy (no trypsin inhibitors), consistent amino-acid profile close to fishmeal.
Frass/digestate returns N-P to soils (A35/W01 links); BSF oil has lauric acid with antimicrobial-adjacent value in young-animal feeds.

Mode of action#

BSF larvae convert wet organic waste (20–40 % efficiency); heat-drying and defatting yield stable meal; the chitinous cuticle fraction acts as a dietary fibre/prebiotic in monogastrics.
SCP: methanotrophs fix methane (CH₄ → biomass) — also a methane-emissions story (EN01 off-gas logic); heterotrophs convert sugars to yeast/bacterial protein.
In salmon/shrimp trials, BSF meal at 25–100 % fishmeal replacement maintains growth in many formulations; species-specific.

Application#

User	Target	Method, timing and specifics
Aquafeed (salmon, shrimp, tilapia)	Fishmeal replacement	BSF meal 5–25 % of diet; DHA algae oil for the fish-oil fraction
Layer/broiler feed	Soy substitution	Insect meal 5–10 %; watch calcium/phosphorus rebalance (FD01 link)
Petfood	Premium protein	Insect and yeast proteins: hypoallergenic positioning, already mainstream in EU petfood
Organic-waste operator	Protein + fertilizer	BSF biocycle on market/agro waste; frass sold as fertilizer (Kenya/LatAm models)
Gas-flaring site / biogas plant	SCP	Methane-to-protein fermenter (String Bio-type)

Limitations#

Price: insect protein still trades above fishmeal in most markets; wins where waste-disposal fees co-finance it.
Substrate rules (EU) exclude manure — the largest waste stream; law may evolve.
Allergy (shellfish cross-reactivity from chitin) needs labeling care; nucleic-acid limits for some SCP in monogastrics.
Scale: global insect meal output is still tiny vs 400+ Mt soybean meal — a Partial verdict on world protein, Replace on specific formula shares.

Insect-resistant (Bt) crop varieties — cotton, maize, soybean, eggplant — instead of broad-spectrum insecticide sprays against bollworms, stem borers and fruit borers

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: insecticide sprays against caterpillar pests · Scope: cotton, maize, soybean, eggplant (where legal) · Evidence: high

The chemical problem#

Before Bt cotton, cotton took a large share of all insecticides used worldwide; in India and China farmers sprayed bollworms 10–30 times per season, often with organophosphates.
Smallholder spraying causes acute poisonings and kills the natural enemies that would otherwise control secondary pests.
Eggplant fruit and shoot borer in South Asia drove some of the highest insecticide loads on any vegetable.

Product overview#

Bt cotton — Cry1Ac or Cry1Ac+Cry2Ab (“Bollgard II”) against bollworms; India adopted it from 2002.
Bt maize — Cry1Ab/Cry1F/Vip3A against corn borers and fall armyworm; the only GM crop grown in the EU (MON810, Spain/Portugal).
Bt soybean (Cry1Ac, Brazil/Argentina) against soybean caterpillars.
Bt eggplant (brinjal) — Bangladesh released varieties to farmers from 2014.
Same protein family as the sprayable Bt in A21 — the plant expresses it, so no spraying is needed.

Active ingredient / Composition#

cry or vip genes from Bacillus thuringiensis, expressed in plant tissue.
Seed is sold with a refuge requirement (non-Bt plants or “refuge in a bag”).

Key facts#

Parameter	Value
Meta-analysis (147 studies)	GM crops on average reduced pesticide quantity by 37 %, raised yields by 22 % and farmer profits by 68 % (insect-resistant crops drive most of the pesticide effect)
India Bt cotton	Large yield and income gains in the first decade; later pink-bollworm resistance to Cry1Ac/Cry2Ab
Regulation	GMO approval needed. Russia bans GM cultivation (Federal Law 358-FZ, 2016); EU allows only MON810; widely grown in the Americas, India, China, Pakistan, parts of Africa

Advantages#

Removes most sprays against the target caterpillars → fewer farmer poisonings, more natural enemies in the field.
Protein is highly specific to certain insect groups; no effect on mammals, bees or most predators at field doses.
Works for smallholders who cannot time sprays well.

Mode of action#

Cry and Vip proteins are activated in the alkaline midgut of susceptible larvae, bind specific gut receptors and form pores → gut paralysis and death.
Pyramids (two or more proteins with different receptors) slow resistance.

Application#

Crop	Pest	Method, timing and specifics
Cotton	Bollworms, pink bollworm	Pyramided Bt hybrids; structured refuge; short season and destruction of crop residues against pink bollworm
Maize	Corn borers, fall armyworm	Bt hybrids with Vip3A where FAW resistance to Cry proteins exists
Eggplant	Fruit and shoot borer	Bt brinjal varieties with border refuge rows
All	Resistance	Monitor larvae surviving on Bt plants; switch to pyramids early

Limitations#

Resistance: pink bollworm in India and several other pests have evolved resistance where refuges were ignored or single-protein crops were kept too long.
Sucking pests (whitefly, jassids, mirids) are not controlled and can increase once broad-spectrum sprays stop.
GMO status blocks use in many markets, including Russia and most of the EU.
Seed price and trait fees; seed quality problems with illegal unapproved seed.

Evidence of displacement — D3: proven displacement at scale#

Assessment (hand-reviewed): Global: Bt cotton cut insecticide active ingredient use by 94.5 million kg (1996–2005, USDA-ARS).

Invasive floating aquatic weed control (water hyacinth, salvinia, water lettuce, alligator weed) with host-specific biocontrol insects — instead of repeated aquatic herbicide spraying

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: aquatic herbicide spraying · Scope: fresh waters · Evidence: high

The chemical problem#

Floating invasive weeds form dense mats that block navigation, irrigation, hydropower intakes and fishing, and create mosquito habitat. The standard response is spraying herbicides onto water. Mats killed by herbicide sink and decompose, which depletes oxygen and kills fish, and the herbicides enter drinking and irrigation water. In the EU, water hyacinth (Eichhornia crassipes) and other species are listed as invasive species of Union concern (Reg. (EU) 1143/2014). They also appear in warm waters in southern Russia.

Lake and pond algal-bloom (cyanobacteria) control by nutrient reduction, biomanipulation (fish-stock management, zooplankton), submerged-plant restoration and floating wetlands — instead of copper sulfate and chemical algicides

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: copper sulfate and chemical algicides · Scope: lakes, ponds, reservoirs · Evidence: high

The chemical problem#

Toxic cyanobacterial blooms (Microcystis, Aphanizomenon, Dolichospermum) are increasing with nutrient loading and warming, including in Russian reservoirs (e.g. the Volga reservoirs and urban ponds). A common “quick fix” is copper sulfate. It is toxic to non-target life, accumulates in sediments and releases cyanotoxins when cells burst. Because the cause (phosphorus and nitrogen) remains, blooms come back and treatment is repeated.

Landfill gas and organic-waste biomethane instead of flaring, fugitive methane and fossil gas

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: flared/vented landfill methane, part of fossil gas · Scope: LFG & MSW organics · Evidence: high

The chemical problem#

Waste sector methane is ~20 % of global anthropogenic CH₄ — open dumps and landfills leak it for decades (organic fraction rots anaerobically whether anyone wants it or not).
Where gas is collected it is often just flared: combustion to CO₂, energy wasted.
The same cities import fossil gas/CNG for buses and industry — paying for the molecule they are burning off at the dump.
Global pledges (the methane-emissions narrative of the 2020s) put waste-sector CH₄ first in line for abatement money.

Product overview#

Landfill gas (LFG) capture: vertical wells + horizontal collectors → flare (baseline compliance) or engine/turbine power, then increasingly upgrading to biomethane (grid injection or bio-CNG).
AD of source-separated MSW organics (EN01’s digester at city scale): food and market waste → biogas + digestate compost; higher gas yield per tonne than landfills and a clean digestate stream.
Integrated waste-to-value chains: collection → sorting → AD → bio-CNG for the collection fleet itself (the Orizon/EverEnviro class of operator in this index).

Active ingredient / Composition#

LFG: CH₄ 45–55 %, CO₂, trace H₂S/siloxanes (cleanup needed before engines/upgrading).
Upgraded biomethane: >97 % CH₄, grid/CNG spec; CO₂ side-stream (future e-fuel feed).

Key facts#

Parameter	Value
Class	Waste-derived biogas infrastructure
Yield	LFG ~100–200 Nm³ CH₄ per tonne MSW over life; AD organics ~60–120 m³ biogas/t
Payback	Power/bio-CNG sales + tipping fees + carbon credits
Climate	Captured CH₄ counts multiply (avoided ~28–80× GWP depending on horizon)

| Standards | ISCC/equivalent for bio-CNG certification in carbon markets |

Advantages#

Mandatory-adjacent: methane rules and carbon finance pay for capture; energy is the bonus — rare among energy substitutions.
City-scale circularity: the waste fleet runs on the waste (bio-CNG buses, EN01 logic at municipal size).
Replaces imported fossil gas/LPG with a fuel that must be collected anyway.
Digestate/compost returns to soils (A35/W01 chain) instead of leachate (W-series).

Mode of action#

Landfill: gas wells under slight vacuum, header to blower/flare or utilization train (H₂S/siloxane filters, chiller dryers).
AD: fully mixed/high-solids digesters at 37–55 °C on source-separated organics (see EN01’s microbiology).

Application#

Site	Target	Method, timing and specifics
Existing landfill	Compliance + power	LFG collection grid, engine gensets; flare as backup
City utility	Grid gas	Upgrading plant (membrane/water scrub) + injection or CNG station
New waste concession	Circular chain	Source-separated organics AD; bio-CNG for collection trucks

| Carbon programme | Credit revenue | Metered CH₄ destruction/avoidance under recognized protocols |

Limitations#

LFG collection never gets 100 % (cover quality rules the result); AD on unsorted MSW is a contamination fight.
Siloxanes/H₂S cleanup adds cost before engines and upgrading.
Gas yield declines after landfill closure — business case is a curve, not a plateau.
Needs concession-law and tariff stability — more a municipal-finance problem than a technical one.

Evidence of displacement — D1: works, adoption not proven#

Assessment (hand-reviewed): Minority/negligible: renewable natural gas 0.36% of Canada’s gas (2021); the rest are projections.

Leather processing with enzymatic unhairing/bating and vegetable or other chromium-free tanning (mimosa, quebracho, chestnut, olive-leaf extract) — instead of sodium sulfide liming and chromium(III) tanning

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: sulfide unhairing and chromium tanning · Scope: leather industry · Evidence: high

The chemical problem#

Most leather is made with sodium sulfide (which dissolves hair and releases toxic H₂S) and chromium(III) salts. Tannery clusters such as Hazaribagh (Bangladesh) and Kanpur (India) discharge chromium and sulfide effluents into rivers, and workers are exposed. Chromium(III) can oxidize to carcinogenic, allergenic chromium(VI) in leather goods, and the EU restricted Cr(VI) in leather articles (REACH Annex XVII, 3 mg/kg).

Lower-toxicity textile dyeing and dye-effluent treatment with biological methods — bio-based indigo reduction and enzymatic indigo routes, microbial pigments, and biological decolorization of dye effluent — instead of sodium dithionite reduction, aniline-derived synthetic indigo and untreated/chemically treated dye effluent

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: dithionite indigo reduction, aniline-based indigo, untreated dye effluents · Scope: denim and dye houses · Evidence: medium

The chemical problem#

Denim dyeing uses synthetic indigo made from aniline, and indigo must be reduced with sodium dithionite, which creates sulfur-rich effluent. Aniline residues have been found in denim. Some azo dyes can split into carcinogenic aromatic amines, and the EU restricts 22 amines in textiles in skin contact. Dye houses in Asia discharge highly coloured effluents into rivers.

Manure methane, ammonia and odour cut by anaerobic digestion with covered storage, low-protein diets balanced with fermentation amino acids, and biological air treatment of livestock houses — instead of open lagoons, sulfuric-acid slurry acidification and masking agents

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: open lagoons, sulfuric-acid acidification, masking agents · Scope: pig, dairy, poultry · Evidence: high (digestion, diet, covers), low (most manure additives)

The chemical problem#

Liquid manure stored in open lagoons emits methane; slurry and litter emit ammonia, a fine-particle precursor and the main driver of nitrogen deposition in livestock regions.
One chemical fix, slurry acidification with concentrated sulfuric acid (used in Denmark), cuts ammonia strongly but brings acid handling risks and adds sulfur to soils.
Odour complaints are often met with masking chemicals that do not reduce emissions.
EU rules are tightening: the revised Industrial Emissions Directive extends to more pig and poultry farms, and national ammonia ceilings apply.

Product overview#

Anaerobic digestion of manure with gas-tight digestate storage — captures methane as biogas (see EN01); small-farm digesters for smallholders.
Covered storage and low-emission spreading (trailing shoe, injection) of digestate.
Low-protein diets balanced with fermentation-made amino acids (lysine, methionine, threonine, valine — see FD01) → less N excreted, less ammonia formed.
Biological air treatment of livestock-house exhaust — biotrickling filters and biofilters (see RM03).

Active ingredient / Composition#

Digestion: anaerobic microbial consortia; biogas ~55–65 % methane.
Diet: crude protein reduced by 1–3 percentage points with crystalline amino acids from fermentation.
Air treatment: nitrifying biofilm on packing material.

Key facts#

Parameter	Value
Low-protein diets (pigs)	Each 1 percentage-point cut in dietary crude protein lowers ammonia emissions by roughly 10 %
Digestion	Captures storage methane and produces energy; digestate needs covered storage and low-emission spreading to avoid shifting losses to ammonia
Acidification	Strongly reduces ammonia (comparator) but needs acid handling and sulfur management
Microbial additives	Many products claim reductions; independent evidence is mostly weak or inconsistent

Advantages#

Digestion turns a methane liability into energy and income (and carbon credits).
Low-protein diets act at the source and save expensive protein feed.
Biological air treatment needs no acid and reduces both ammonia and odour.
Smallholder digesters replace firewood and charcoal (EN01).

Mode of action#

Anaerobic digestion converts manure organic matter to methane in a closed vessel, so it is captured rather than released from the lagoon.
Less dietary N → less urea in urine → less ammonia formed by urease in the slurry.
Nitrifying bacteria in biofilters oxidize ammonia to nitrite/nitrate in the trickling water.

Application#

Situation	Target	Method, timing and specifics
Large pig/dairy farms	Methane, energy	Digester + gas-tight digestate storage; CHP or biomethane
Smallholder farms	Methane, cooking fuel	Prefabricated household biodigesters
All pig and poultry farms	Ammonia at source	Phase feeding with reduced crude protein and fermentation amino acids
Mechanically ventilated houses	Ammonia, odour	Biotrickling filter on exhaust (RM03)
Field application	Ammonia	Trailing shoe or injection of digestate/slurry

Limitations#

Digesters need scale, capital and operating skill; leaks erase the methane benefit.
Low-protein diets need accurate amino-acid balancing to keep performance.
Air treatment is costly for naturally ventilated barns.
Do not rely on unproven microbial manure additives.

Evidence of displacement — D1: works, adoption not proven#

Assessment (hand-reviewed): Mismatch: Danish slurry acidification (4% → 14%, 2011–2015) is a chemical (sulfuric acid) treatment, not digestion or biofilters.

Mediterranean fruit fly control by the sterile insect technique instead of insecticide bait sprays

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: aerial organophosphate bait sprays · Scope: citrus and fruit regions · Evidence: moderate–high

The chemical problem#

The Mediterranean fruit fly (Ceratitis capitata) attacks more than 250 fruits. Detections trigger quarantines that block exports.
The standard response was aerial bait sprays of malathion and other organophosphates — over orchards and, in California, over cities — with residue, environmental and public-acceptance problems.

Product overview#

Sterile insect technique (SIT): male-only strains (genetic sexing) are mass-reared, sterilised and released weekly over target areas. Programmes include the Moscamed barrier at the Mexico–Guatemala border (since 1977/1982), California’s Preventive Release Program over the Los Angeles basin (since 1996), the Valencian Community programme in Spain (since 2007, over >140,000 ha of citrus), South Africa and Chile.

Metal-contaminated soils, mine tailings and smelter sites managed by phytostabilization, phytoextraction and rhizoremediation (gentle remediation options) instead of excavation, soil washing and inert capping

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: excavation, soil washing, bare or inert-capped tailings · Scope: smelter surroundings, mine tailings, metal-polluted farmland · Evidence: high (stabilization), medium–low (extraction speed)

The chemical problem#

Smelters and mines leave large areas with diffuse Cd, Pb, Zn, Cu and As contamination — far too big to excavate.
Bare tailings blow and wash away, spreading metals for decades.
The chemical alternative, soil washing with acids or EDTA, destroys soil structure and life and creates contaminated wash water.

Product overview#

Phytostabilization — tolerant plants (grasses, shrubs, trees) plus amendments (compost, lime, biochar, iron oxides) immobilize metals in the root zone and stop erosion.
Phytoextraction — (hyper)accumulator plants (e.g. Noccaea, Sedum, Pteris for As) take metals into harvestable shoots; nickel “phytomining” can even recover metal for sale.
Phytomanagement — growing non-food biomass crops (willow, poplar, miscanthus, fibre crops) on contaminated land: risk reduction plus income.
Rhizoremediation — roots stimulate microbes that degrade residual organic pollutants (after RM01).

Active ingredient / Composition#

Plant species chosen for metal tolerance and climate.
Amendments: compost, biosolids (WC03), biochar, lime, iron/manganese oxides.
Optional: plant-growth-promoting and metal-tolerant bacteria and mycorrhiza.

Key facts#

Parameter	Value
Field-scale evidence	European COST Action 859 reviewed many field trials: phytostabilization and phytomanagement deliver risk reduction; phytoextraction of Cd/Zn is slow
Tailings	Arid and semi-arid tailings can be stabilized with compost + tolerant native plants, cutting dust and erosion
Time	Stabilization: visible within 1–3 seasons; extraction: years to decades
Cost	Usually far below excavation for large areas

Advantages#

Treats hectares or square kilometres at a cost no excavation project can match.
Keeps soil in place and alive; creates vegetation, landscape and sometimes biomass income.
Stops wind and water erosion of tailings — the main exposure route near many mines.
Uses residues (compost, biosolids, biochar) as amendments.

Mode of action#

Roots and amendments bind or precipitate metals (sorption, complexation, pH change) → lower mobility and plant uptake.
Hyperaccumulators transport metals to shoots via specialised transporters and store them in vacuoles.
Vegetation cover intercepts dust and reduces water infiltration and leaching.

Application#

Situation	Target	Method, timing and specifics
Mine tailings (arid/semi-arid)	Dust and erosion control	Compost + tolerant native grasses/shrubs; irrigation for establishment
Farmland near smelters	Lower Cd/Pb in food	Switch to non-food or low-accumulating crops; lime/compost amendments
Nickel-rich (ultramafic) soils	Metal recovery	Ni hyperaccumulator cropping (“agromining”)
Residual hydrocarbons	Polishing	Grasses/legumes for rhizoremediation after landfarming (RM01)

Limitations#

Phytoextraction is too slow for most redevelopment deadlines.
Biomass from extraction crops is contaminated — needs controlled disposal or metal recovery.
Deep contamination below the root zone is not reached.
Regulators may not accept “risk management in place” instead of concentration targets.

Microalgal omega-3 oils (DHA/EPA) instead of fish oil and krill oil

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: fish and krill oil for EPA/DHA · Scope: supplements, infant formula, premium food · Evidence: high

The chemical problem#

Omega-3 demand runs on wild marine oil: forage-fishery fish oil for supplements and aquaculture feed, plus Antarctic krill oil for the premium shelf. The krill fishery competes with the food web that sustains penguins, seals and whales; forage-fish supplies are capped and El-Nino-sensitive; fish-oil quality varies with oxidation and contaminant scares; and farmed salmon - itself a main omega-3 channel - now carries less EPA/DHA per fillet as feeds reduce fish-oil inclusion. The paradox: the marine food chain makes these fatty acids at the bottom, and the industry catches the middle of the chain to harvest them.

Mosquito and blackfly control with Bacillus thuringiensis israelensis (Bti) and Lysinibacillus sphaericus larvicides, source reduction, and plant-based repellents — instead of organophosphate larvicides and pyrethroid space fogging

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: organophosphate larvicides and routine insecticide fogging · Scope: public health and wetlands · Evidence: high

The chemical problem#

Municipal mosquito control in many countries, including Russian cities and southern floodplains (the Volga delta, Kuban, Rostov), relies on fogging with pyrethroids or organophosphates and on OP larvicides. Fogging kills pollinators and non-target insects, drifts into homes, and has limited effect on mosquitoes, which are often resistant. Temephos in water harms aquatic invertebrates, and resistance to it is common in Aedes aegypti.

Mycotoxin detoxification in feed with specific enzymes and microbes — fumonisin esterase (FumD), trichothecene-degrading bacterium BBSH 797, zearalenone hydrolase

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: ineffective binders and chemical detoxification; reduces drug use caused by mycotoxin immunosuppression · Species: pigs, poultry, cattle · Evidence: high

The chemical problem#

Global feed surveys find mycotoxins in the majority of feed and grain samples: deoxynivalenol (DON), fumonisins (FUM), zearalenone (ZEN) and aflatoxins. Wet harvests in Russia and Eastern Europe often give high DON and ZEN. Effects include feed refusal, immunosuppression (vaccine failures, secondary infections treated with antibiotics), reproductive disorders in sows (ZEN), and liver damage. Clay binders (bentonites) bind aflatoxins well but do not bind DON, fumonisins or ZEN effectively. Chemical detoxification (ammoniation, formaldehyde) is hazardous and not authorized for most uses.

Mycotoxin risk managed by enzymes and biological detoxification instead of clay binders alone

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: clay-binder-only mycotoxin programs · Scope: feed grain & compound feed · Evidence: high for lead enzymes

The chemical problem#

Mycotoxins are the grain chain’s tax: aflatoxin B1 is an IARC Group 1 carcinogen, fumonisins hit equine/swine health, zearalenone hits reproduction, DON kills intake.
The default industry answer — clay binders (bentonite/clinoptilolite) — adsorb aflatoxin well, fumonisin/ZEN/DON poorly, and add dead weight to every tonne.
Climate shifts push toxin geography poleward; hot-region maize (this index’s Africa/ME belt) fights aflatoxin constantly.

Product overview#

Enzymatic detoxification: FUMD fumonisin esterase (BIOMIN-era science, now EU feed-additive approved) hydrolyzes fumonisins to non-toxic metabolites in the gut; zearalenone hydrolase/lactonase degrades ZEN; trichothecene-detoxifying enzymes under development.
Microbial detox cultures: rumen- and soil-derived isolates (Eubacterium/Nocardioides-class) that de-epoxidate DON or convert aflatoxin — commercial products in some markets.
Prevention first (the catalogue’s upstream pattern): resistant varieties (A-series logic), harvest/drying discipline, storage without moisture pockets (A31 hermetic links), and biological control of Aspergillus flavus (atoxigenic-strain products — A01-family logic).

Active ingredient / Composition#

FUMD: recombinant fumonisin esterase (EC 3.1.1.87), dosed in feed-additive formulation;
Binder-grade clays remain for aflatoxin where they genuinely work (honest pairing).

Key facts#

Parameter	Value
Class	Enzymatic/biological mycotoxin detoxification
Regulatory	EU feed-additive authorizations for FUMD/ZEN enzyme products
Coverage	Aflatoxin: binders/biocontrol; fumonisin/ZEN: enzymes; DON: partial

| Dose logic | Diagnose (test grain) → treat the measured toxin (threshold pattern, V-series) |

Advantages#

Degrades toxins instead of diluting them — no dead tonnage, works on the toxins binders miss.
Survives gut passage to act in vivo where contamination was unavoidable.
Same enzyme-vendor class as FD01/FD03 (fermentation suppliers already in the index).
Pairs with atoxigenic-strain prevention in hot-region maize (Africa/ME relevance).

Mode of action#

FUMD hydrolyzes fumonisin’s tricarballylic side chains → hydrolyzed fumonisin (non-inhibitory on ceramide synthase);
ZEN hydrolase opens the lactone ring → non-estrogenic metabolites;
Atoxigenic A. flavus strains outcompete toxin producers in the field (competitive exclusion, V01’s logic on a fungus).

Application#

Situation	Target	Method, timing and specifics
Fumonisin-hot maize (swine/horse)	Growth/health	FUMD enzyme product per authorization; test-and-treat
ZEN contamination (breeding herds)	Fertility	ZEN-detox enzyme; straw/grain testing first
Aflatoxin-prone regions	Prevention	Atoxigenic-strain field treatment + binder at spikes only
Storage season	Prevention	Dry, hermetic, cool storage (A31); moisture monitoring

Limitations#

No single tool covers all mycotoxins yet — programs combine test, prevent, degrade, bind.
Enzyme products cost more per tonne than clay; economics need the loss-avoidance case.
DON enzymology is still maturing (Partial).
Testing discipline is the gatekeeper: enzymes without diagnosis are guesswork.

Natural antioxidants — tocopherols, rosemary extract, ascorbyl palmitate — instead of BHA and BHT

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: BHA (E320), BHT (E321) · Scope: fats, oils, snacks, feeds · Evidence: high

The chemical problem#

BHA is listed by the US NTP as reasonably anticipated to be a human carcinogen; EFSA re-evaluations cut its ADI; BHT carries endocrine-activity debate and consumer-label rejection.
Both are cheap, effective, and therefore everywhere fats sit in a package — the classic “works fine, looks bad on the label” pair.
Oxidation itself is the enemy (rancidity, waste); the question is only which molecule buys the shelf-life.

Product overview#

Tocopherols (E306–309): vitamin-E-class antioxidants from vegetable-oil deodorizer distillates — the default natural antioxidant for oils and fats.
Rosemary extract (E392): diterpenes (carnosic acid/carnosol) — high efficacy in animal fats and snacks; the workhorse of the “clean-label” switch.
Ascorbyl palmitate (E304) and citric acid chelators: fat-soluble vitamin C class + metal-chelating synergists (the blend is the product).
Algal astaxanthin and tocopherol combos: specialty oils (omega-3) where the antioxidant is also a premium active (FI01/FI04 adjacency).

Active ingredient / Composition#

Tocopherol concentrates (mixed isomers, 50–70 %), rosemary extracts standardized to carnosic acid (5–20 % in oil carriers); blend dosing 100–500 ppm active — dosage discipline replaces BHA’s blunt 50–200 ppm.

Key facts#

Parameter	Value
Class	Natural/plant antioxidants
Regulatory	E306–309, E392, E304 approved (EU/EAEU); BHA/BHT still legal but label-flagged
Cost	Rosemary/tocopherol routes typically 1.5–4× BHA/BHT

| Technique | Blends + nitrogen flushing + light barriers do the rest of the shelf-life work |

Advantages#

Removes the NTP/EFSA talking points from the label (the FI01/FI02 pattern again).
Tocopherol is a vitamin (FI04 dual-function logic); rosemary extract reads as food, not chemistry.
Same supply chains as vitamins/extracts already mapped in this index.

Mode of action#

Phenolic H-donation quenching lipid radicals (ROO·→ROOH chain break) — same physical chemistry as BHA/BHT, biogenic molecules; carnosic acid additionally regenerates tocopherol (synergy).

Application#

Use	Target	Method, timing and specifics
Frying/salad oils	Rancidity	Tocopherol + rosemary blend; monitor peroxide value
Snacks/cereals	Shelf life	Rosemary extract + oxygen-barrier packaging
Omega-3 oils/fish products	Strong oxidation load	Tocopherol + ascorbyl palmitate + rosemary; cold chain
Feed fats (FD links)	Premix stability	Natural antioxidant programs in premium feed lines

Limitations#

Higher dose and cost than BHA/BHT; flavor contribution of rosemary needs managing.
Heat stability and carry-through differ per matrix — reformulation work per product.
Supply of standardized rosemary extract is concentrated (drought-region agriculture).

Assessment (hand-reviewed): Only market-research figures (natural antioxidants in pet food) — weak sources, not counted.

Natural antioxidants (mixed tocopherols, rosemary extract, other plant polyphenols) instead of ethoxyquin in fishmeal, fish oil and aquafeeds

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: ethoxyquin in marine ingredients and aquafeeds · Species: all farmed aquatic animals · Evidence: high

The chemical problem#

Fishmeal and fish oil are rich in polyunsaturated omega-3 fats, which oxidize quickly. Fishmeal can even self-heat and catch fire during shipping. Ethoxyquin, a synthetic quinoline antioxidant (originally a rubber chemical and pesticide), was used for decades and was historically required for bulk fishmeal transport. Ethoxyquin carries over into farmed fish fillets. EFSA could not confirm its safety (data gaps, and the impurity p-phenetidine, a possible mutagen). The EU suspended ethoxyquin as a feed additive in 2017 (Regulation (EU) 2017/962), with transition periods. Ethoxyquin is not authorized as a food additive in the EU.

Neonatal calf diarrhoea without prophylactic antibiotics — dam vaccination, colostrum management, lactic-acid-bacteria probiotics and oral rehydration

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: routine antibiotics in milk or milk replacer, feeding untreated waste milk with antibiotic residues · Species: calves · Evidence: high

The chemical problem#

Calves up to 4 weeks old receive a large share of all antibiotics on dairy farms, often prophylactically in milk. Most neonatal diarrhoea is caused by viruses and protozoa (rotavirus, coronavirus, Cryptosporidium parvum), where antibiotics do not work, plus ETEC K99 (F5) in the first days of life. Feeding waste milk (from antibiotic-treated cows) spreads resistant bacteria. The WHO classifies fluoroquinolones and 3rd/4th-generation cephalosporins as “highest priority critically important” antimicrobials.

New World screwworm eradication by the sterile insect technique instead of insecticide wound treatment

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: insecticide wound treatment and myiasis losses · Scope: livestock and wildlife, area-wide · Evidence: high

The chemical problem#

The New World screwworm (Cochliomyia hominivorax) lays eggs in wounds of warm-blooded animals; larvae eat living tissue. Before eradication it caused heavy losses in cattle, sheep, goats and wildlife across the Americas.
Control relied on inspecting every animal and treating wounds with insecticides — labour-intensive, repeated and never-ending, because flies re-invaded.

Product overview#

Sterile insect technique (SIT): millions of flies are mass-reared, sterilised with gamma radiation and released by air every week. Wild females mate with sterile males and lay infertile eggs; populations collapse. Proposed by E. F. Knipling in the 1950s, proven on Curaçao (1954), then applied in Florida (1958–59), the south-western USA, Mexico and Central America. A barrier of sterile flies is now kept at the Panama–Colombia border by the COPEG plant (USA–Panama).

Nitrogen-fixing and nutrient-mobilizing microbes (Azospirillum, Azotobacter, engineered root-associated diazotrophs) for maize, wheat and rice instead of part of the urea dose

Mon, 01 Jan 0001 00:00:00 +0000

Replaces (partial): 10–25 % of mineral N on cereals · Scope: maize, wheat, rice, sugarcane · Evidence: high (Azospirillum), medium (engineered diazotrophs)

The chemical problem#

Cereals take most of the world’s nitrogen fertilizer. Urea dominates, and its price follows natural gas.
Typical cereal nitrogen-use efficiency is only 30–50 %: the rest leaves as nitrate, ammonia or N₂O.
Legumes solve this with rhizobia (A35); cereals have no nodules, so they depend on mineral N.

Product overview#

Azospirillum brasilense (strains Ab-V5 and Ab-V6 in Brazil; Az39 in Argentina). Associative N fixation plus strong phytohormone effects on roots. Brazil sells millions of doses per year for maize, wheat and pasture grasses.
Azotobacter and Gluconacetobacter diazotrophicus — free-living or endophytic fixers; widely sold in India, also for sugarcane.
Engineered root-associated diazotrophs — e.g. Klebsiella variicola / Kosakonia sacchari strains with nitrogenase regulation re-tuned so they keep fixing N in fertilized soil (commercial in US maize since 2019).
Nutrient-mobilizing companions — P- and Zn-solubilizing Bacillus and Pseudomonas often co-formulated (see A36).

Active ingredient / Composition#

A. brasilense: ≥2 × 10⁸ CFU/mL, liquid; seed treatment 100–200 mL per 25 kg seed, or in-furrow/foliar.
Azotobacter / consortia: 10⁸–10⁹ CFU/g or /mL, carrier- or liquid-based.
Engineered diazotrophs: in-furrow liquid at planting.

Key facts#

Parameter	Value
Field response	Meta-analyses of Brazilian and Argentine trials: average yield gains of a few percent to ~10 % at equal N, or equal yield with reduced N
N replacement	Usually 10–25 % of the N dose; legume-level fixation is not reached
Registration	Brazil MAPA inoculant register; India FCO biofertilizer schedule; EU FPR 2019/1009 (microbial plant biostimulant, PFC 6(A))
Cost	Typically a few US$ per hectare — far below the N it can replace

Advantages#

Cheap per hectare, fits existing seed-treatment and planting equipment.
Root-growth effects also improve water and P uptake in dry seasons.
Large, multi-year field datasets exist (Brazil, Argentina), unlike many new biologicals.
Lowers both fertilizer cost exposure and N₂O emissions.

Mode of action#

Associative fixation: nitrogenase in bacteria on and inside roots reduces N₂ to NH₃; part reaches the plant.
Phytohormones: Azospirillum makes auxin (IAA), gibberellins and nitric oxide → more root hairs and lateral roots → better uptake of fertilizer N already in the soil (this explains much of the yield effect).
Engineered strains: the nifA/nifL regulation is modified so ammonium in soil no longer switches nitrogenase off.

Application#

Crop	Target	Method, timing and specifics
Maize	N efficiency	A. brasilense on seed or in-furrow at planting; cut top-dress N by ~25 % only after own strip trials
Wheat	Tillering and N uptake	Seed inoculation; consider foliar re-inoculation at tillering
Rice, sugarcane	N supply	Azotobacter/Gluconacetobacter consortia, seedling dip or sett treatment
Soy–maize rotation	System N	Co-inoculation of soy (A35) plus Azospirillum on the following maize

Limitations#

Response depends on soil, strain and inoculant quality; poor products (low CFU, contaminated) are common in some markets.
Bacteria are sensitive to seed-treatment fungicides and heat; follow compatibility tables and plant soon after inoculation.
Engineered strains are GMOs in the EU and many other jurisdictions; they are not legal everywhere.
Gains are partial — no cereal inoculant replaces the whole N dose.

Odour, H₂S, ammonia and VOC emissions treated by biofilters, biotrickling filters and bioscrubbers instead of chemical scrubbers (caustic/hypochlorite/acid) and thermal oxidizers

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: chemical scrubbers and thermal oxidizers for dilute, biodegradable emissions · Scope: wastewater, waste, livestock, food industry, biogas · Evidence: high

The chemical problem#

Odour from sewage works, compost sites and rendering plants is a top cause of public complaints and permit trouble.
The standard fix — chemical scrubbers — needs a constant supply of caustic soda, hypochlorite and acid, with storage risk and chemical waste.
Thermal oxidizers burn natural gas to destroy VOCs present at low concentration — high energy and CO₂ per unit of pollutant removed.

Product overview#

Biofilters — air flows through a moist packed bed (compost, wood chips, bark, peat-free media) colonized by microbes that oxidize odorants.
Biotrickling filters — inert packing with a trickling nutrient solution; higher loading, better pH control, smaller footprint; used for H₂S and ammonia.
Bioscrubbers — pollutants absorbed into water, then degraded in a separate bioreactor.
Biological biogas desulfurization — H₂S removal by sulfur-oxidizing bacteria instead of iron salts or caustic.

Active ingredient / Composition#

Microbial communities: sulfur-oxidizing bacteria (Thiobacillus, Acidithiobacillus), nitrifiers, heterotrophic VOC degraders, fungi for hydrophobic VOCs.
Media: compost/wood chips (biofilters) or plastic/lava-rock packing (biotrickling).

Key facts#

Parameter	Value
Full-scale retrofit	Existing chemical scrubbers at a wastewater plant were converted to biotrickling filters for H₂S with high removal and no scrubbing chemicals
Typical removal	High (often >90 %) for H₂S, reduced sulfur compounds, ammonia and readily biodegradable VOCs at suitable residence times
Operating cost	Mostly fans and water; no chemical purchases; media replacement every few years (biofilters)
Limits	Hydrophobic and chlorinated VOCs, very high concentrations, sudden load swings

Advantages#

No hazardous chemicals stored on site.
Low energy compared with thermal oxidation of dilute streams.
Media can be made from residues (wood chips, compost).
Converts existing scrubber towers (retrofit) with modest capital.

Mode of action#

Pollutants dissolve into the water film on the packing; microbes oxidize them: H₂S → sulfate, NH₃ → nitrite/nitrate, VOCs → CO₂ and water.
Biotrickling filters remove acidic products with the trickling liquid, keeping pH in range.

Application#

Situation	Target	Method, timing and specifics
Sewage pumping stations, inlet works	H₂S, odour	Biotrickling filter or retrofit of existing caustic scrubber
Composting halls, waste sites	Odour, ammonia	Open or enclosed biofilter with acid pre-scrubber for high NH₃
Livestock houses	Ammonia, odour	Biotrickling/biofilter on exhaust air (see LE02)
Biogas plants	H₂S	Biological desulfurization before engines (EN01)
Food and rendering plants	Odour, VOC	Biofilter or bioscrubber sized on odour load tests

Limitations#

Needs constant moisture, temperature and nutrient control; dries out or clogs if neglected.
Footprint of open biofilters is large.
Not suited to chlorinated solvents, very high VOC loads or intermittent emissions without buffering.
Start-up takes weeks while the biomass establishes.

Evidence of displacement — D3: proven displacement at scale#

Assessment (hand-reviewed): National: biofilters, bioscrubbers and multistage biological systems are most exhaust-air treatment units installed in Germany (2010).

Oil and petroleum-product pollution clean-up by bioremediation — nutrient biostimulation, oil-degrading microbial preparations, landfarming/biopiles and phytoremediation — instead of chemical dispersants, burning and landfilling

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: chemical dispersants, burning and landfilling · Scope: oil-contaminated soils, shorelines and water · Evidence: high

The chemical problem#

Russia has one of the world’s largest oil-contamination legacies: pipeline leaks in West Siberia and Komi (e.g. the Usinsk spill of 1994), and the Norilsk diesel spill of 2020 (about 21,000 t into rivers and soil). Standard responses include burning (air pollution, PAHs), dispersants at sea (Deepwater Horizon used about 7 million litres; toxicity concerns for plankton and corals), and digging up and landfilling soil. Oil hydrocarbons are naturally biodegradable, and nature supplies the microbes.

Oil-reservoir and pipeline souring (H2S) control by nitrate injection (biocompetitive exclusion by nitrate-reducing bacteria) — instead of continuous biocide dosing

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: continuous biocide dosing · Scope: oil production · Evidence: high

The chemical problem#

Seawater or produced-water injection feeds sulfate-reducing microorganisms (SRM) in reservoirs. They produce H₂S: “souring”, which is deadly to workers, corrodes pipes and lowers oil value. The standard countermeasure is continuous biocide dosing (glutaraldehyde, THPS). Biocides penetrate poorly into the reservoir, select tolerant microbes, and reach the sea in produced-water discharges.

Product overview#

Nitrate injection (calcium nitrate or sodium nitrate added to the injection water) stimulates nitrate-reducing bacteria (NRB) and nitrate-reducing sulfide-oxidizing bacteria (NR-SOB):

Oilfield produced water treated biologically instead of chemical-only conditioning and disposal

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: chemical-only produced-water conditioning · Scope: onshore oil & gas · Evidence: mixed, case-proven

The chemical problem#

Every barrel of oil comes with several barrels of water: saline, oily, dosed with biocides, demulsifiers and scale inhibitors before injection or ponding.
Chemical conditioning makes the water manageable, not clean: ponds seep, injection pressures rise, and any reuse (irrigation, fracturing make-up) needs the organics out.
In the producing regions of this index (Gulf, North Africa, Nigeria, Andes), produced-water handling is both an environmental flashpoint and a water-resource opportunity in arid zones.

Product overview#

Hydrocarbon bioremediation: native/deployed consortia degrade dissolved and dispersed hydrocarbons (E03’s land-spill logic in a tank); oily-sludge digestion.
Biological polishing trains: DAF/flash tanks (capture float oil) → aerobic MBBR/MBR on dissolved organics (W01 hardware) → desalination where reuse demands it.
Reuse routes: treated produced water for fracturing make-up, crop irrigation of tolerant species (California/Permian programs), or dust control — turning a disposal cost into a water asset.
Source-side allies: nitrate against reservoir souring instead of biocides (I04) cuts the biocide mass at the origin.

Active ingredient / Composition#

Hydrocarbonoclastic bacteria (Pseudomonas, Rhodococcus, Alcanivorax-class) with nutrient dosing (N/P) and aeration; residence hours–days depending on load.

Key facts#

Parameter	Value
Class	Biological treatment of industrial wastewater
Volumes	Typically 3–8 bbl water per bbl oil (worse in mature fields)
Targets	BTEX, TPH, phenols; salinity needs separate desalination

| Reuse bars | Irrigation/fracturing specs drive the treatment train depth |

Advantages#

Degrades the organics instead of transferring them to sludge/ponds.
Reuse converts a cost line into a water resource where the field is arid (much of this index’s producing geography).
Same consortia/vendors as E03 spills and W01 effluents — technology transfer, not invention.

Mode of action#

Aerobic hydrocarbon catabolism: alkane/aromatic pathways (alkB, ring-hydroxylating dioxygenases) to biomass + CO₂; N/P nutrition balanced to the load; biosurfactant-producing strains assist emulsified uptake (CM03 adjacency).

Application#

Site	Target	Method, timing and specifics
Central facility	Disposal quality	Skim tank → MBBR/MBR biological polishing on dissolved organics before injection
Oily sludge pits	Closure	Bioremediation of pit contents before landform (E03 practice)
Reuse program	Irrigation/fracturing	Treat-to-spec train incl. desalination; regulatory engagement early

Limitations#

Salinity is the wall: biology cleans organics, not salt — reuse beyond tolerant irrigation/fracturing needs desalination (energy).
Programs are field-specific: water chemistry, acreage, and law decide economics; no universal design.
Production chemistry (demulsifiers/biocides) can inhibit the biology — coordinate chemical selection.

Evidence of displacement — D0: no verified evidence#

No verified figure was found for this substitution.

On-farm and regional biofactories (multiplication units, media, quality control) for microbial bio-inputs — Bacillus, Trichoderma, Beauveria, Bt, beneficial insects — instead of importing finished chemical pesticides and fertilizers

Mon, 01 Jan 0001 00:00:00 +0000

Replaces (partial): imported chemical pesticides/fertilizers and imported finished biologicals · Scope: farms, cooperatives, regional plants · Evidence: medium–high

The chemical problem#

Biological alternatives exist for many chemical uses (A-series, NU02), but finished products are often imported, expensive and short-lived, so farmers default to the chemical.
Live microbes and insects lose viability in long, hot supply chains.
Brazil showed another route: large farms and cooperatives multiply Bacillus, Trichoderma, Beauveria and other agents on the farm, at a fraction of the cost of finished products. A 2024 federal law regulates on-farm production for own use.

Product overview#

Liquid fermentation kits — stainless or plastic bioreactors (hundreds to thousands of litres) with sterilizable media, aeration and temperature control, supplied with certified starter strains.
Solid-state units — trays or bags of rice or other grain for fungal agents (Beauveria, Metarhizium, Trichoderma).
Mass-rearing units — insectaries for predatory mites, Trichogramma and other beneficials.
Quality-control lab — CFU counting, purity and identity checks (microscopy, plating, PCR) for every batch.
Service model — the equipment supplier sells strains, media, training and QC as a package.

Active ingredient / Composition#

Certified strains from a registered supplier, culture media (molasses, yeast extract, salts), sterile water, air filters.
Output: liquid concentrate (Bacillus, often 10⁸–10⁹ CFU/mL) or conidia on solid substrate.

Key facts#

Parameter	Value
Scale	Brazil: on-farm multiplication is widespread on large grain and cotton farms
Cost	Main driver: on-farm product at a fraction of finished-product cost
Main risk	Contamination (including human pathogens) and low or variable CFU if sterility and QC are weak
Regulation	Brazil: federal bio-inputs law (2024) for on-farm production for own use; most other countries still require a registered product

Advantages#

Fresh, high-viability product exactly when the crop needs it; no cold chain.
Lower cost per hectare than finished imported products.
Builds local technical capacity (strains, fermentation, QC) — an import-substitution story.
Equipment, media and QC are a recurring business for suppliers.

Mode of action#

Same biology as the finished products (A04, A13, A21, A25, NU02): multiplication simply happens near the field.
Solid-state fermentation favours aerial conidia of entomopathogenic and antagonistic fungi; submerged fermentation suits bacteria.

Application#

Situation	Target	Method, timing and specifics
Large grain/cotton farms	Bacillus, Trichoderma for seed and soil	Liquid kits with certified strains; batch QC before every application
Cooperatives	Shared production	Regional unit with a lab and an agronomist; members collect fresh product
Horticulture, orchards	Beneficial insects	Mass-rearing unit or regional insectary (A24, A30)
Countries without on-farm rules	Legal compliance	Produce through a registered regional biofactory instead

Limitations#

Quality is the whole game: unsupervised production can multiply contaminants instead of the target strain.
Illegal in many countries for products not registered (only own use, if at all).
Needs trained staff, clean water, power and a lab.
Strain theft and IP disputes when strains are copied from commercial products.

Evidence of displacement — D1: works, adoption not proven#

Assessment (hand-reviewed): No figure for on-farm biofactories: the ‘85% of soybean area’ found refers to inoculation (see A35); Brazil’s biopesticides ~6% of the pesticide market (2023/24) is sector-level.

On-farm culture, PCR panels, rapid tests and veterinary laboratory services for livestock and aquaculture — treat what is diagnosed instead of blanket and prophylactic antibiotic treatment

Mon, 01 Jan 0001 00:00:00 +0000

Replaces (partial): blanket and prophylactic antibiotic use · Scope: dairy, pigs, poultry, aquaculture · Evidence: high

The chemical problem#

Most antibiotic use in food animals is given without a diagnosis: every mastitis case is tubed, whole groups are dosed on suspicion, hatcheries dose prophylactically.
Many clinical mastitis cases are culture-negative or caused by bacteria that cure without antibiotics, yet they receive the same treatment.
Residue findings in shrimp and milk lead to trade rejections; regulators now demand diagnosis before using critically important antimicrobials (e.g. EU Reg. 2019/6).

Product overview#

On-farm milk culture — selective plates (e.g. tri-plates) read after 24 h; treat only Gram-positive cases, not Gram-negative or no-growth cases.
PCR panels and rapid tests — multiplex PCR for mastitis, respiratory and enteric pathogens; lateral-flow tests at farm level.
Aquaculture PCR screening — post-larvae and broodstock tested for WSSV, AHPND, EHP before stocking (pairs with SG04 and F04).
Veterinary laboratories — culture and sensitivity testing so the narrowest effective drug is chosen.
Antimicrobial-use benchmarking — the Dutch model: farm-level use data, targets and vet–farmer contracts.

Active ingredient / Composition#

Culture media, PCR reagents (primers, probes, enzymes — themselves bioeconomy products), antibody-based rapid-test strips, lab services.

Key facts#

Parameter	Value
Culture-guided mastitis treatment	Randomized trial: antibiotic use for clinical mastitis halved without hurting short-term cure or milk loss
National case	The Netherlands cut veterinary antibiotic sales by more than half in a few years with benchmarking, diagnosis and restrictions on critical drugs
Global context	Antimicrobial use in food animals projected to keep rising in middle-income countries without such measures
Turnaround	On-farm culture: ~24 h; PCR: hours; rapid tests: minutes

Advantages#

Directly removes unnecessary treatments — often the cheapest antibiotic reduction available.
Lower drug costs and fewer discarded-milk days.
Evidence for export buyers that residue and AMR rules are met.
Builds the “information is an input” model the catalogue’s second trend describes.

Mode of action#

Diagnosis sorts cases into “treat”, “do not treat” and “treat with a narrow drug”.
Screening before stocking (aquaculture) stops pathogens entering ponds, avoiding later mass treatment.
Benchmarking changes prescribing behaviour across a sector.

Application#

Situation	Target	Method, timing and specifics
Dairy clinical mastitis (mild/moderate)	Fewer treatments	On-farm culture; treat Gram-positive only; severe cases treated at once
Pig and poultry outbreaks	Right drug, right group	Lab culture/PCR and sensitivity before group treatment
Shrimp hatcheries and farms	Clean stock	PCR screening of broodstock and post-larvae batches
National/sector programmes	Lower total use	Use data per farm, targets, vet contracts

Limitations#

Needs training, discipline and a 24-h wait that farmers must accept.
Lab access is poor in many rural regions; costs per test can deter use.
Diagnostics without alternatives (vaccines, genetics, hygiene) only reduce, not remove, antibiotic need.

Assessment (hand-reviewed): UK intramammary antimicrobial treatments down 25% (2015–2020), attributed to mastitis-control programmes — diagnostics’ role not isolated.

Organic and organo-mineral fertilizers made from biogas digestate, compost, vermicompost and insect frass instead of part of mineral NPK

Mon, 01 Jan 0001 00:00:00 +0000

Replaces (partial): mineral NPK share · Scope: field and horticultural crops · Evidence: high (soil fertility), medium (yield parity)

The chemical problem#

Mineral NPK feeds the crop but not the soil: long-term mineral-only programmes lose soil organic matter, structure and water-holding capacity.
Mineral N depends on fossil gas; phosphate rock is finite and often carries cadmium (see NU04).
At the same time, organic residues (manure, food waste, sludge, crop residues) are dumped, burned or landfilled, where they emit methane.

Product overview#

Digestate — the residue of anaerobic digestion (biogas). Liquid fraction is rich in ammonium N; solid fraction carries P and organic matter.
Compost and vermicompost — aerobically stabilized organic matter; slow-release N, P, K plus humus.
Insect frass — black soldier fly or cricket excrement plus exuviae (chitin); a fertilizer with biostimulant properties.
Organo-mineral fertilizers (OMF) — granules combining an organic carrier (compost, digestate solids, filter cake) with mineral nutrients; can be spread with standard fertilizer equipment.

Active ingredient / Composition#

Product	Typical nutrients (fresh or as sold)	Notes
Liquid digestate	2–6 kg NH₄-N/m³, P and K	High ammonia-loss risk at spreading (use injection or trailing hose)
Compost	1–2 % N (mostly organic), 0.5–1 % P₂O₅	Slow release; rebuilds organic carbon
Insect frass	~2–4 % N, P, K, chitin	Legal as a fertilizer after heat treatment (EU: 70 °C, 60 min)
Organo-mineral granule	e.g. 40 % organic matter + 4–10 % N/P₂O₅	Example in the index: 40 % OM, 6 % humic+fulvic, 1.5 % N, 4 % P₂O₅

Key facts#

Parameter	Value
Long-term effect	Organic amendments raise soil organic carbon, microbial biomass and aggregate stability over years
Yield	Organic-only systems yield on average less than conventional (gap depends on crop and N supply); combined organic + mineral programmes close most of the gap
Regulation	EU FPR 2019/1009 component material categories for compost (CMC 3) and digestate (CMC 4, 5); national rules for sludge-derived products
Logistics	Low nutrient density → transport cost limits radius unless dried or granulated (OMF)

Advantages#

Closes the loop between waste treatment (biogas, composting, insect farms) and crop nutrition.
Builds soil organic matter, water retention and biological activity that mineral fertilizer does not supply.
Organo-mineral granules handle like mineral fertilizer, so farmers do not need new spreaders.
Cuts landfill and open-dump methane at the source.

Mode of action#

Organic N mineralizes gradually through soil microbial activity, matching crop uptake better than a single urea dose.
Organic carbon feeds soil biology, improves structure and cation-exchange capacity, and keeps P more available.
Frass chitin stimulates chitinolytic microbes and plant defence (a biostimulant side effect).

Application#

Situation	Target	Method, timing and specifics
Arable land near biogas plants	N and P supply	Liquid digestate by trailing hose or injection in spring; expect a mineral-fertilizer equivalent of roughly 50–70 % of total N (higher with low-emission spreading)
Vegetables, orchards	Organic matter	Compost 10–30 t/ha before planting; reduce base NPK accordingly
Field crops far from waste sources	Convenience	Organo-mineral granules through standard spreaders
Nurseries, high-value horticulture	Fertility plus biostimulation	Vermicompost or frass mixed into substrate (see CE01)

Limitations#

Nutrient content varies batch to batch — analyse before calculating rates.
Contaminants: heavy metals, plastics and pathogens depend on feedstock; certified schemes (quality-assured compost/digestate) are essential.
Ammonia losses from digestate can be large without low-emission spreading.

Paint and coating preservation with less isothiazolinone biocide — formulation hygiene, low-water-activity and bio-based boosters

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: routine MIT/CMIT/OIT/BIT loading · Scope: in-can + film preservation · Evidence: emerging

The chemical problem#

Waterborne paints are paint and microbial medium: in-can spoilage (bacteria) and dry-film mildew (fungi) are controlled almost everywhere by isothiazolinones — MIT, CMIT, OIT, BIT.
These are among Europe’s top contact allergens: regulatory action hit cosmetics first (EU MIT restrictions from 2015/2017), leaving paints and household products as a major remaining consumer/painter exposure source; dermatology registries track the epidemic.
Disposed paint water carries the biocides into wastewater (E-series logic).

Product overview (reduction ladder, honestly ordered)#

Formulation hygiene and low-water-activity hurdles: clean manufacture, low-pH/high-surfactant hostile matrices, airless packaging — cut the needed biocide dose before substituting it.
Dose-optimization with rapid microbiological control: dosing to measured challenge (diagnose→threshold, the catalogue’s pattern) instead of blanket max-label rates.
Bio-based boosters: chitosan (film antifungal adjunct), plant extracts, antimicrobial peptides — research-to-niche commercial; they reduce isothiazolinone load rather than replace it.
Film protection by design: mildewcidal pigments (zinc oxide classes) and formulation of the film itself to be non-nutritive.

Active ingredient / Composition#

Hurdle components: pH adjusters, chelators, low-NP surfactant systems; chitosan 0.1–1 % film adjunct; booster dosing at fraction-of-label rates.

Key facts#

Parameter	Value
Class	Preservation strategy (hurdle + reduced biocide + bio-boosters)
Regulatory	EU biocidal products regime (BPR) drives review; cosmetic MIT limits signaled direction
Allergy reality	Paint remains a recognized isothiazolinone exposure source

| Verdict honesty | No general biocide-free waterborne paint is proven shelf-stable today |

Advantages#

Lower allergen load for painters and occupants; lower wastewater biocide mass.
Hygiene/hurdle measures cost little and often improve batch consistency anyway.
Keeps waterborne (PC01’s gain) while addressing its chemical shadow.

Mode of action#

Hurdle: water activity, pH and substrate hostility slow growth so a smaller biocide dose holds the challenge; chitosan’s cationic glucosamine chains disrupt fungal membranes at the film surface.

Application#

Stage	Target	Method, timing and specifics
Paint plant	In-can load	Hygiene audit → challenge-test-based dosing (not label-max)
Formulation	Hurdle design	Low-NP binder/surfactant selection; chelator package
Film spec	Mildew	ZnO-class + chitosan adjunct; humid-chamber testing
Consumer info	Exposure	Sensitizer labeling discipline; SDS honesty

Limitations#

Emerging, stated plainly: biocide-free waterborne decorative paint is not a proven category; this article rates Partial.
Bio-boosters add cost and can interact with rheology/film properties.
Under-dosing risks spoilage — challenge testing is non-negotiable when cutting dose.

Peat-free and peat-reduced growing media (coir, wood fibre, composted bark, green-waste compost, sphagnum farming) instead of extracted peat

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: peat in growing media · Scope: nurseries, greenhouses, retail compost · Evidence: high

The chemical problem#

Professional and retail growing media are still dominated by peat, extracted from drained bogs in Northern Europe, the Baltics, Russia and Canada.
Drained and extracted peatlands emit CO₂ for decades; peatlands store more carbon than all the world’s forests combined despite covering a small share of land.
Policy: England has committed to ending peat sales in retail growing media (legislation pending); Germany, Ireland and others have reduction targets; retailers set their own phase-outs.

Product overview#

Coir (coco peat, coir pith, chips) — coconut-husk by-product from South and Southeast Asia; washed/buffered to remove salts.
Wood fibre — defibrated softwood chips; light, open structure, used up to 30–50 % in mixes.
Composted bark — from sawmills; stable, disease-suppressive.
Green-waste compost — quality-assured compost (5–30 % of mixes).
Sphagnum farming — cultivated sphagnum moss biomass on rewetted peatland (renewable, early commercial).
Other — rice hulls, biochar fractions, perlite (mineral).

Active ingredient / Composition#

Constituent	Typical share in peat-free mixes	Key property
Coir pith/chips	20–60 %	High water holding, re-wettable; needs washing/buffering
Wood fibre	20–50 %	Air-filled porosity, low density; immobilizes N
Composted bark	10–40 %	Structure, disease suppression
Green compost	5–30 %	Nutrients, microbial activity; salt and pH vary

Key facts#

Parameter	Value
Performance	Peat-free mixes give comparable plant quality when irrigation and N feeding are adapted
Climate	Rewetting peatlands is one of the cheapest land-based mitigation options
Supply	Coir supply is concentrated in India and Sri Lanka; wood fibre and bark come from sawmill residues
Certification	Growing-media responsible-sourcing schemes rate constituents for environmental and social impact

Advantages#

Keeps peatland carbon in the ground.
Uses by-products (coconut husk, sawmill residues, green waste).
Composted bark and compost add disease suppression.
Meets retailer and policy demand for peat-free products.

Mode of action#

Coir holds water but drains differently from peat; wood fibre and bark provide air space.
Composts supply microbes that compete with root pathogens (Pythium, Phytophthora).
Wood fibre locks up N during microbial breakdown → extra N feeding needed.

Application#

Situation	Target	Method, timing and specifics
Retail potting soil	Peat-free product	Coir + wood fibre + green compost blends
Container nurseries	Plant quality	Bark + wood fibre + coir; adjust irrigation (dries faster on top) and N
Greenhouse vegetables	Soilless culture	Coir slabs instead of peat or rock wool (CE02)
Propagation	Uniform germination	Fine coir + wood fibre; small peat share where still needed

Limitations#

Different water and nutrient behaviour requires grower retraining.
Coir needs washing and buffering (Na, K) and long-distance shipping.
Wood fibre’s N immobilization and compost’s salt variability need quality control.
Some propagation uses still lack a full peat replacement.

Evidence of displacement — D3: proven displacement at scale#

Assessment (hand-reviewed): National: peat share in German potting soils fell from 59% to 33% (2019–2024).

Pesticide-free weed management in towns, parks, railways-adjacent areas and gardens — design, mulching, mowing regimes ("let it grow"), hot water/steam, and bio-based contact herbicides (pelargonic acid, acetic acid)

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: herbicide spraying in public spaces and gardens · Scope: urban and household · Evidence: medium–high

The chemical problem#

Herbicides sprayed on pavements, kerbs and gravel do not bind to soil. Rain washes them straight into drains and rivers, so urban use contributes a disproportionate share of herbicides detected in surface water compared with its small tonnage. Children, pets and residents are exposed in parks and schoolyards. France (Loi Labbé) banned pesticides in public green spaces from 2017 and for private gardeners from 2019. Denmark, the Netherlands and Belgium (Flanders, Wallonia) strongly restrict or ban herbicide use on public hard surfaces, and hundreds of cities worldwide are pesticide-free.

Petroleum-contaminated soil and drill cuttings cleaned by bioremediation (landfarming, biopiles, bioaugmentation, biostimulation) instead of excavation to landfill, incineration/thermal desorption and chemical oxidation

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: excavation to landfill, thermal treatment, chemical oxidation · Scope: oilfields, depots, refineries, drill cuttings · Evidence: high

The chemical problem#

Spills at wells, pipelines, depots and workshops leave large volumes of oily soil; drilling produces oily cuttings.
The default answers are excavation to hazardous landfill (expensive, moves the contamination), thermal desorption/incineration (fuel-intensive, sterilizes soil) or chemical oxidation (strong oxidants, by-products).
Regions with heavy oil production (West Siberia, the Niger Delta, the Gulf, Latin American oilfields) carry large legacy areas.

Product overview#

Landfarming — oily soil spread in thin layers, tilled for aeration, fertilized (N, P) and kept moist; microbes degrade hydrocarbons over months.
Biopiles — engineered piles with aeration pipes, nutrients, moisture control and leachate collection; faster and smaller footprint than landfarming.
Bioaugmentation — adding selected hydrocarbon-degrading microbial consortia, useful where native degraders are scarce or the soil was sterilized.
Biostimulation — nutrients, oxygen, surfactants (incl. biosurfactants, see I06) to speed native microbes.
Phyto- and rhizoremediation of residual hydrocarbons — grasses and legumes that stimulate degraders in the root zone (RM02).

Active ingredient / Composition#

Hydrocarbon-degrading bacteria and fungi: Pseudomonas, Rhodococcus, Acinetobacter, Alcanivorax, Mycobacterium, white-rot fungi.
Inputs: N and P fertilizer (C:N:P around 100:10:1), bulking agents (wood chips, straw), water, air.

Key facts#

Parameter	Value
Typical duration	Landfarming: one to a few seasons; biopiles: weeks to months
What degrades well	Alkanes, diesel, light/medium crude, monoaromatics (BTEX)
What degrades slowly	High-molecular PAHs, asphaltenes, weathered heavy oil
Cost	Usually a fraction of thermal treatment or hazardous landfill per tonne

Advantages#

Destroys hydrocarbons (to CO₂, water, biomass) instead of moving them.
Low energy; uses farm-type equipment and cheap inputs.
Treated soil keeps biological activity and can be reused for site restoration.
Works on site, avoiding transport of hazardous waste.

Mode of action#

Microbes oxidize alkanes via monooxygenases and aromatics via dioxygenases, using them as carbon and energy sources.
Oxygen, nutrients and moisture are the limiting factors — engineering them is what landfarming and biopiles do.
Biosurfactants increase hydrocarbon availability to cells.

Application#

Situation	Target	Method, timing and specifics
Diesel/light crude spill at depot	TPH below limit	Excavate to on-site biopile; aerate, add N/P, keep 40–60 % water-holding capacity
Oilfield pits and cuttings	TPH reduction	Landfarm on lined cells; till every 2–4 weeks in the warm season
Cold climates (Siberia, Arctic)	Short season	Covered/heated biopiles; cold-adapted bioaugmentation cultures
Residual hydrocarbons after treatment	Polishing, revegetation	Rhizoremediation with grasses/legumes (RM02)

Limitations#

Slow for heavy oil and PAH-rich residues; may need combination with other methods.
Chlorinated solvents, PFAS and metals are not removed by this approach.
Landfarming needs space and leachate/vapour control.
Commercial “miracle cultures” vary in quality; demand site-specific treatability tests.

Assessment (hand-reviewed): US Superfund: incineration fell from 29% to 6% of ex-situ treatment projects — bioremediation’s share not stated in the quote.

Piglet post-weaning diarrhoea without pharmacological zinc oxide and colistin — live oral E. coli vaccine, fermented liquid feed, probiotics and low-protein diets

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: medicinal zinc oxide and colistin in weaner diets · Species: pigs · Evidence: high

The chemical problem#

Zinc oxide at 2,500–3,000 ppm (about 20–30 times the nutritional requirement) was used for decades against post-weaning diarrhoea (PWD). About 90 % passes into manure, and zinc accumulates in soils and harms soil life and aquatic ecosystems. High zinc co-selects for antibiotic resistance (e.g. livestock-associated MRSA, zinc-resistance gene czrC). The EU withdrew all veterinary ZnO products from June 2022.
Colistin in piglets is a major driver of mcr-1 resistance (see V01). The EMA recommended drastic reductions.
PWD is caused mainly by enterotoxigenic E. coli (ETEC) with F4 (K88) and F18 fimbriae, triggered by weaning stress, low feed intake and a high-protein diet.

Product overview#

A combined program has replaced ZnO in Denmark, the Netherlands and other EU countries:

Plant biostimulants (seaweed extracts, protein hydrolysates, humic and fulvic substances) instead of extra mineral nitrogen and synthetic plant growth regulators for stress

Mon, 01 Jan 0001 00:00:00 +0000

Replaces (partial): extra mineral N “for safety” and stress-oriented synthetic growth regulators · Scope: field and horticultural crops · Evidence: medium

The chemical problem#

A large share of applied nitrogen never reaches the crop: it leaches as nitrate or leaves as N₂O and ammonia. Farmers add extra mineral N as insurance against stress years.
Stress management is also chemical: synthetic growth regulators and repeated foliar NPK “tonics” are sprayed to carry crops through heat, drought and transplant shock.
Regulators now cap the habit: the EU Farm-to-Fork target is −20 % fertilizer use by 2030, nitrate-vulnerable-zone rules limit N rates, and MRLs cover growth-regulator residues.

Product overview#

A plant biostimulant acts on plant physiology or the rhizosphere to improve nutrient-use efficiency, abiotic-stress tolerance or quality — regardless of its own nutrient content. Four commercial families matter:

Plant-based meat and dairy analogues and cultivated (cell-cultured) meat and seafood instead of a share of conventional meat and its antibiotic, antiparasitic and feed-chain chemical inputs

Mon, 01 Jan 0001 00:00:00 +0000

Replaces (partial): a share of conventional meat and its chemical inputs · Scope: plant-based and cultivated meat/seafood · Evidence: high (plant-based), low–medium (cultivated)

The chemical problem#

Animal products use most agricultural land and feed-crop inputs, and most antibiotics sold for food animals.
Food-system studies find that animal products provide a minority of calories and protein but cause the majority of food-related land use and emissions.
As in AP01, the substitution is indirect: fewer animals → fewer antibiotics, less feed chemistry, less manure. Ratings stay Partial or Watchlist.

Product overview#

Plant-based meat and dairy — pea, soy, wheat and fava proteins texturized by high-moisture extrusion; fats and flavours (incl. fermentation-made heme or fats) for meat-like products; oat, soy and pea drinks.
Hybrid products — plant proteins with mycoprotein or cultivated cells (see AP01).
Cultivated meat and seafood — animal muscle and fat cells grown in bioreactors on culture media; approved for sale in Singapore (2020), the USA (2023) and Israel (2024).

Active ingredient / Composition#

Plant-based: protein isolates/concentrates (60–90 % protein), plant fats, binders (methylcellulose or fibres), flavours.
Cultivated: cell lines (stem or immortalized cells), growth media (amino acids, glucose, growth factors — increasingly animal-serum-free), scaffolds (plant or seaweed-based).

Key facts#

Parameter	Value
Footprint	Global LCA dataset: plant proteins have far lower land use and emissions per gram of protein than beef, lamb and most animal products
Cultivated cost	Techno-economic analysis: large cost reductions in media and bioreactors are needed to reach commodity meat prices
Approvals	Cultivated meat: Singapore (2020), USA (2023), Israel (2024); several countries ban or restrict it
Regulation	Plant-based: normal food law (labelling disputes over “meat” names). Cultivated: EU novel food; Russia/EAEU: no approval route yet

Advantages#

No antibiotics, hormones or slaughter; lower zoonotic risk.
Plant-based products use existing food-processing equipment and crops (pea, soy) — a market for local protein crops.
Cultivated seafood could relieve pressure on wild stocks.

Mode of action#

Extrusion aligns plant proteins into fibrous, meat-like structures.
Cultivated meat: cells proliferate in suspension or on scaffolds, then differentiate into muscle and fat tissue.

Application#

Product	Target	Method, timing and specifics
Burgers, mince, nuggets	Volume market	Plant-based from pea/soy texturized protein
Dairy drinks and desserts	Lactose-free, dairy-free	Oat, soy, pea bases (plus AP01 proteins for functionality)
Premium meat and seafood	Niche, regulatory pilots	Cultivated or hybrid cultivated/plant products where approved
Protein-crop processors	New demand	Pea, fava, soy protein isolation for food-tech buyers

Limitations#

Plant-based sales growth slowed after 2021 in several Western markets; taste, price and “ultra-processed” concerns.
Cultivated meat: high cost, limited bioreactor capacity, regulatory bans in some jurisdictions.
Nutrition equivalence (iron, B12, protein quality) must be designed in.

Post-harvest decay control of citrus, pome, stone and tropical fruit with antagonistic yeasts (Metschnikowia, Candida, Aureobasidium), hot-water treatment and chitosan coatings — instead of synthetic post-harvest fungicides

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: synthetic post-harvest fungicide dips and waxes · Products: fruit · Evidence: medium–high

The chemical problem#

Post-harvest fungicides are applied directly to the edible product, days before consumption. Citrus green and blue moulds (Penicillium digitatum, P. italicum) are controlled with imazalil, thiabendazole and OPP; bananas and mango with prochloraz, thiabendazole and imazalil. These leave the highest residues found in retail fruit (citrus peel is also used in food: zest, marmalade). Packing-house Penicillium populations are resistant to imazalil and thiabendazole in many regions. Workers in packing houses are exposed daily, and dip wastewater is a disposal problem.

Potato sprout suppression in storage with spearmint oil (carvone), orange oil, ethylene and cold storage — instead of chlorpropham (CIPC)

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: chlorpropham (CIPC) fogging of stored potatoes · Products: potatoes · Evidence: high

The chemical problem#

For about 60 years CIPC was fogged into potato stores worldwide (and still is in many countries, including CIS markets). Its residues were among the most common pesticide residues in EU food. The EU did not renew CIPC in 2019 (Regulation (EU) 2019/989) because consumer safety could not be demonstrated, partly because of the metabolite 3-chloroaniline. CIPC also soaks into store walls and contaminates later untreated potatoes for years.

Poultry coccidiosis control with live Eimeria vaccines (and phytogenic support) instead of continuous in-feed ionophores and chemical coccidiostats

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: continuous in-feed ionophores and chemical anticoccidials · Species: poultry · Evidence: high

The chemical problem#

Almost all conventional broilers receive anticoccidials in feed for their whole life. Ionophores are extremely toxic to horses (monensin LD₅₀ in horses about 2–3 mg/kg bw), and accidental feed contamination has killed many horses, cattle and dogs worldwide. Eimeria parasites have developed resistance to all anticoccidial drugs used for long periods. Ionophores are antibacterial, and in Scandinavia and the EU, narasin-resistance genes (narAB) in Enterococcus have been linked to ionophore use. Residues in eggs from cross-contamination of layer feed are a recurring food-safety finding.

Poultry gut health without antibiotic growth promoters and colistin — competitive exclusion cultures, Bacillus probiotics and bacteriophages

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: in-feed antibiotic growth promoters (AGPs), prophylactic colistin and fluoroquinolones · Species: poultry · Evidence: high

The chemical problem#

AGPs (low-dose antibiotics in feed to “improve growth”) select for resistant bacteria that pass to people via meat, manure and workers. The EU banned all AGPs in 2006 (Reg. (EC) 1831/2003). Many countries in Asia, Africa and the CIS still use them, or use therapeutic antibiotics routinely in drinking water.
Colistin is a last-resort antibiotic for human multidrug-resistant infections. In 2015 the transferable resistance gene mcr-1 was discovered in pigs and chickens in China. After China banned colistin as a growth promoter (2017), mcr-1 prevalence in animals and humans fell significantly.
Fluoroquinolones (enrofloxacin) in poultry → resistant Campylobacter in humans. The USA withdrew enrofloxacin approval for poultry in 2005 for this reason.

Product overview#

Three proven biological tools protect the chick gut:

Poultry red mite (Dermanyssus gallinae) control with predatory mites (Androlaelaps casalis, Cheyletus eruditus), silica/diatomaceous earth and heat — instead of illegal fipronil and carbamate/pyrethroid sprays

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: fipronil (illegal in food animals), carbamates, organophosphates and pyrethroids in layer houses · Species: poultry · Evidence: medium–high

The chemical problem#

The poultry red mite (Dermanyssus gallinae) hides in cracks and feeds on hens’ blood at night. It causes anaemia, stress, feather pecking, lower egg production and death, and costs the EU industry hundreds of millions of € per year. It also carries pathogens (Salmonella, avian influenza, Erysipelothrix). Because few legal products existed and mites are resistant to pyrethroids and carbamates, some operators used the veterinary drug fipronil, which is forbidden in food-producing animals. This caused the 2017 EU fipronil egg scandal: millions of eggs were recalled across more than 40 countries and hundreds of farms were blocked. OPs and carbamates remain in use in many countries.

Precision-fermentation dairy and egg proteins (whey, casein, ovalbumin) and fungal biomass protein (mycoprotein) instead of a share of antibiotic- and land-intensive animal protein

Mon, 01 Jan 0001 00:00:00 +0000

Replaces (partial): a share of animal protein and its chemical inputs · Scope: food ingredients and foods · Evidence: high (products), medium (environment at scale)

The chemical problem#

Animal protein carries the heaviest chemical footprint per kg of protein: most of the world’s antibiotics are used in food animals, and feed crops take fertilizer and pesticides.
The catalogue’s veterinary, feed and livestock emissions collections reduce these inputs per animal. Alternative proteins reduce the number of animals needed for the same protein.
This collection is outside the catalogue’s usual “chemical X → biological Y” frame: the substitution is indirect. Ratings stay Partial.

Product overview#

Precision fermentation — microbes (yeasts such as Pichia/Komagataella, fungi such as Trichoderma, bacteria) produce a specific animal protein: β-lactoglobulin (whey), caseins, ovalbumin, lactoferrin. The protein is identical to the animal one; the microbe is removed.
Mycoprotein / fungal biomass — the whole fungal mycelium (e.g. Fusarium venenatum, Neurospora, Aspergillus species) is the food: high protein and fibre, meat-like texture.
Microbial biomass protein — bacterial or algal single-cell protein for food (gas fermentation for feed is covered in FD06).

Active ingredient / Composition#

Precision-fermented whey/casein: >90 % target protein after purification; lactose- and cholesterol-free.
Mycoprotein: ~45 % protein and ~25 % fibre (dry basis), low saturated fat.

Key facts#

Parameter	Value
Market status	Mycoprotein on sale for decades (UK); precision-fermented whey in US products; Israel, Singapore and the USA have approval routes
Modelling	Replacing 20 % of per-capita ruminant meat with microbial protein by 2050 was projected to roughly halve deforestation and related emissions
Regulation	EU novel-food authorization (EFSA) required; Russia/EAEU: state registration of new food products; GM-host labelling rules differ
Cost	Precision-fermented proteins still cost more than dairy protein; mycoprotein is near price parity in some markets

Advantages#

No antibiotics, hormones or zoonotic risk in production.
Much lower land and water use per kg protein; can run on sugar from residues.
Functionally identical proteins (whey, casein) for cheese, yoghurt and bakery.
Uses the same fermentation infrastructure as enzymes and vitamins (FI04, I02).

Mode of action#

A gene for the animal protein is inserted into a microbial host; the host secretes the protein during fermentation; downstream processing purifies it.
Mycoprotein: continuous fermentation of a filamentous fungus on glucose, then heat treatment (RNA reduction), dewatering and texturizing.

Application#

Product	Target	Method, timing and specifics
Dairy-alternative cheese, ice cream, yoghurt	Dairy functionality	Precision-fermented casein/whey in blends with plant fats
Bakery, confectionery, sports nutrition	Egg/whey replacement	Precision-fermented ovalbumin or β-lactoglobulin
Meat alternatives	Texture, protein	Mycoprotein alone or hybrid with plant protein (see AP02)
Food manufacturers	Supply security	Long-term offtake contracts with fermentation producers

Limitations#

High capital cost of fermentation capacity; scale-up is the main bottleneck.
Novel-food approval takes years and differs by country.
Energy and sugar inputs determine the environmental benefit.
Consumer acceptance of “lab” or GM-host products varies; mycoprotein can cause rare allergic reactions.

Prickly pear control in Australia with Cactoblastis cactorum instead of chemical and mechanical clearing

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: arsenic poisoning and mechanical clearing · Scope: invasive cactus in Australia · Evidence: high

The chemical problem#

Introduced Opuntia cacti (O. stricta, O. inermis) had overrun about 24 million hectares (60 million acres) of Queensland and New South Wales by the 1920s, making the land unusable.
Control relied on arsenic pentoxide and other poisons, burning and digging. At about £10 per acre, chemical and mechanical clearing would have cost far more than the land was worth — and the cactus spread faster than it could be cleared.

Product overview#

The Commonwealth Prickly Pear Board searched the Americas for natural enemies. The moth Cactoblastis cactorum from Argentina was released from 1926, with eggs distributed across the infested districts. Larvae tunnel through the cactus pads, and secondary rots finish the plants.

Process equipment for residue-to-product plants — anaerobic digesters and biogas upgrading, composting turners and granulation lines, biomass pelleting, pyrolysis and carbonization kilns — instead of incinerators, landfill, open lagoons and open burning

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: landfill, lagoons, open burning, incineration of wet waste · Scope: household to industrial · Evidence: high

The chemical problem#

The waste and energy collections (WC, EN, BR) show biological routes for residues. Each needs a plant, and each plant needs equipment and someone to build it.
Without local builders and service, projects stall and residues are burned or dumped.

Product overview#

Anaerobic digesters — household/prefab (EN01), farm (LE02) and industrial (CSTR, UASB, covered lagoon), plus biogas cleaning (desulfurization, see RM03) and upgrading to biomethane.
Composting and organic-fertilizer lines — windrow turners, in-vessel composters, crushers, granulators, dryers, coolers and packaging.
Biomass pelleting and briquetting lines — for agro-residue fuels (EN05).
Pyrolysis, carbonization and torrefaction kilns — for biochar (CR01) and biocoal; continuous rotary kilns to batch retorts.
EPC/turnkey builders — design, build, commission and operate.

Active ingredient / Composition#

Not applicable (equipment). Key specifications: feedstock range, throughput (t/day), gas yield/methane content, emissions control, automation, service network.

Key facts#

Parameter	Value
Digesters	Mature from household to multi-MW scale; performance depends on feedstock and operation
Composting	Mechanized turning and aeration shorten composting and stabilize quality
Pyrolysis	Modern kilns capture and burn pyrolysis gases; traditional earth kilns are highly polluting
Business models	Equipment sale, turnkey EPC, build-own-operate, carbon-credit co-financing

Advantages#

Converts a disposal cost into gas, fertilizer, fuel or biochar.
Often co-financed by carbon credits (methane avoidance, biochar removals).
Local fabrication possible for simpler equipment (turners, pellet mills, small digesters).

Mode of action#

Digesters provide controlled anaerobic conditions for methanogenic microbes; composters provide aeration and mixing for aerobic microbes; pyrolysis kilns heat biomass without oxygen to fix carbon in char.

Application#

Residue	Plant	Equipment and specifics
Manure, food waste, POME, vinasse	Biogas	Digester + gas cleaning + engine or upgrading unit (EN01, EN04, BR02)
Market and municipal organics	Compost / organic fertilizer	Turners, screens, granulation line (NU03, WC02)
Straw, husks, EFB	Pellets or biochar	Pellet line (EN05) or pyrolysis kiln (CR01)
Smallholders	Household energy	Prefabricated digesters (EN01, LE02)

Limitations#

Operation, not equipment, is the main failure point (feedstock supply, skilled staff).
Emissions control matters: leaky digesters and dirty kilns erase the climate benefit.
Capital and financing; carbon-credit income is volatile.

Evidence of displacement — D1: works, adoption not proven#

Assessment (hand-reviewed): Mismatch: Italian sludge disposal routes are not evidence about biogas/composting equipment.

Pulp bleaching with xylanase enzyme pre-bleaching and ECF/TCF processes (oxygen, peroxide, ozone) — instead of elemental chlorine bleaching; with biological effluent treatment

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: elemental chlorine and hypochlorite bleaching · Scope: pulp and paper industry · Evidence: high

The chemical problem#

Bleaching pulp with elemental chlorine creates chlorinated organics (AOX), including dioxins and furans, which were found in fish downstream of mills in the 1980s. In Russia, the Baikalsk Pulp and Paper Mill (operated 1966–2013) discharged effluents into Lake Baikal, a UNESCO World Heritage Site. It became a symbol of industrial pollution and was finally closed in 2013; its sludge ponds remain a remediation challenge.

Recovered phosphorus (struvite and other recovered phosphates from biological wastewater and digester streams) instead of fertilizer made from cadmium-bearing phosphate rock

Mon, 01 Jan 0001 00:00:00 +0000

Replaces (partial): rock-derived P fertilizer share; chemical P precipitation at treatment plants · Scope: municipal and food-industry wastewater · Evidence: medium–high

The chemical problem#

Mineral P fertilizer comes from phosphate rock, a finite resource concentrated in a few countries (Morocco/Western Sahara holds most reserves).
Sedimentary rock contains cadmium; the EU limits Cd in fertilizer to 60 mg/kg P₂O₅ under the Fertilising Products Regulation.
Wastewater plants remove P to protect rivers — often by dosing iron or aluminium salts, which binds the P into a sludge plants cannot use easily.

Product overview#

Enhanced biological phosphorus removal (EBPR) — polyphosphate-accumulating bacteria take up P in the activated-sludge process, replacing metal-salt dosing.
Struvite recovery — in the digester, the P is released again; adding magnesium to the digester liquor precipitates struvite (MgNH₄PO₄·6H₂O) as clean crystals.
Use as fertilizer — granular struvite is a slow-release N-P-Mg fertilizer with very low heavy-metal content.
A side benefit for the plant: controlled struvite precipitation prevents scale that blocks pipes and pumps.

Active ingredient / Composition#

Struvite: ~5–6 % N, ~28 % P₂O₅ (in pure form ~29 %), ~16 % MgO.
Cd and other metals usually far below rock-derived fertilizers.

Key facts#

Parameter	Value
Agronomic efficiency	Meta-analysis: struvite performs similar to soluble mineral P fertilizers on average; slower in alkaline soils
Release	Low water solubility, dissolves with root acids → slow release, low leaching
Recovery share	Struvite reactors typically recover a fraction (often 10–40 %) of the plant’s P load; ash-based routes recover more
Regulation	EU FPR 2019/1009 component material category CMC 12 (precipitated phosphate salts and derivates)

Advantages#

Low cadmium — a clean P source where soil Cd is a concern.
Domestic P supply for import-dependent countries.
Cuts metal-salt purchases at the treatment plant and reduces pipe scaling.
Slow release suits perennial and horticultural crops and lowers P run-off.

Mode of action#

EBPR bacteria store P as polyphosphate under alternating anaerobic/aerobic conditions → P is concentrated in biomass instead of precipitated with Fe/Al.
In anaerobic digestion the P is released into the liquor; controlled pH and Mg addition crystallize struvite.
In soil, struvite dissolves near roots as they release organic acids, supplying P, N and Mg.

Application#

Situation	Target	Method, timing and specifics
Large EBPR plants with digesters	P recovery	Struvite reactor on the digester liquor (dewatering filtrate)
Arable crops, neutral/acid soils	P supply	Granular struvite at sowing, blended with soluble P where fast early P is needed
Turf, nurseries, perennials	Slow-release P	Struvite granules as a low-leaching P source
Food-industry effluents (dairy, potato)	P recovery	On-site struvite precipitation from high-P streams

Limitations#

Recovers only part of the P in wastewater; the rest stays in sludge (see WC03) unless ash-based recovery is added.
Slower P release in alkaline soils; combine with soluble P for young crops.
Needs a larger plant with digestion — not viable for small works.
Public acceptance and fertilizer approval of “sewage-derived” products differ between countries.

Refractory gold ore processing by bacterial biooxidation (BIOX® and similar tank bioleaching) — instead of roasting; with biological cyanide destruction of tailings water

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: roasting of arsenical gold concentrates · Scope: gold mining · Evidence: high

The chemical problem#

In refractory ores, gold is locked inside pyrite and arsenopyrite. The classic treatment is roasting, which releases SO₂ and arsenic trioxide. The Giant Mine (Yellowknife, Canada) left about 237,000 t of arsenic trioxide dust stored underground, a remediation liability costing more than 1 billion Canadian dollars.

Product overview#

Biooxidation uses acidophilic iron- and sulfur-oxidizing microorganisms (Acidithiobacillus ferrooxidans, A. thiooxidans, Leptospirillum ferriphilum, Sulfobacillus, Ferroplasma) in stirred, aerated tanks at 35–45 °C. They dissolve the sulfide matrix and release the gold for cyanidation. Arsenic ends up as stable ferric arsenate precipitate instead of airborne As₂O₃.

Riboflavin (vitamin B2) by fermentation instead of multi-step chemical synthesis

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: chemical synthesis · Scope: feed, food and pharma riboflavin · Evidence: high

The chemical problem#

Riboflavin was made industrially by a multi-step chemical synthesis (ribose from glucose, condensation with 3,4-xylidine derivatives, ring closure), with organic solvents, high reagent use and waste per kilogram.
Most riboflavin goes into animal feed premixes, so cost and volume matter more than anything else.

Product overview#

Engineered production strains (Bacillus subtilis, the fungus Ashbya gossypii, earlier the yeast Candida famata) overproduce riboflavin from sugars and vegetable oil in a one-step fermentation. BASF switched its Ludwigshafen production from chemistry to Ashbya fermentation in the 1990s; DSM and Chinese producers use B. subtilis.

Road and pavement de-icing with bio-based deicers (acetates from fermentation, agricultural by-product brines such as beet-molasses residues) and salt-reduction practices — instead of heavy use of chloride salts and chloride "reagent" mixtures

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: excessive chloride salts · Scope: municipal winter maintenance · Evidence: high for the chloride problem

The chemical problem#

Tens of millions of tonnes of road salt are used each year worldwide, and large quantities in Russian cities. Chloride does not degrade: it accumulates in soils, groundwater, streams and lakes. Long-term data show a steady rise in the salinity of fresh water in cold regions (“freshwater salinization syndrome”). The damage includes roadside trees (a major cause of urban tree decline in Moscow and St Petersburg), corrosion of cars, bridges and rebar, and harm to aquatic life.

Ruminant gastrointestinal nematode control without blanket macrocyclic lactone dosing — nematode-trapping fungus Duddingtonia flagrans, tannin-rich forages, targeted selective treatment (FAMACHA) and grazing management

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: routine whole-flock or whole-herd anthelmintic dosing · Species: sheep, goats, cattle, horses · Evidence: high

The chemical problem#

Anthelmintic resistance in Haemonchus contortus, Teladorsagia and Trichostrongylus is widespread in sheep and goats worldwide: resistance to benzimidazoles, levamisole and macrocyclic lactones, often on the same farm. Resistance in cattle nematodes (Cooperia, Ostertagia) to ivermectin is growing. Routine whole-flock treatment is the main driver.
Ecotoxicity: ivermectin is excreted mostly unchanged in dung. It kills dung beetle and dung fly larvae and slows dung decomposition. This was first shown in Nature in 1987 and confirmed in many studies. It is also highly toxic to aquatic invertebrates.
In Russia and the CIS, ivermectin products (Ivermek and others) are used very widely, often as blanket treatments.

Product overview#

A sustainable parasite control program (the SCOPS/COWS principles in the UK; WAAVP guidelines):

Salmon lice control with cleaner fish (lumpfish, wrasse), lice-barrier cage designs ("snorkel", skirts), functional feeds and fallowing — instead of chemical bath and in-feed delousing

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: chemical delousing baths and in-feed insecticides · Species: salmon · Evidence: medium–high

The chemical problem#

Salmon lice (Lepeophtheirus salmonis, Caligus spp.) are the largest health problem in sea-cage salmon farming, and they also threaten wild salmon and sea trout. Intensive chemical use produced multi-drug resistance in lice (emamectin, pyrethroids, azamethiphos, and even hydrogen peroxide). The chemicals harm non-target crustaceans: pyrethroids and azamethiphos are toxic to lobsters and shrimp near farms, and teflubenzuron and diflubenzuron persist in sediments and disturb moulting crustaceans.

Saprolegnia (water mould) and egg-fungus control without malachite green and formalin — UV water treatment, salt, hydrogen peroxide, antagonistic bacteria and hatchery hygiene

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: malachite green and formalin · Species: hatchery and pond fish, including sturgeon (important in Russia) · Evidence: medium

The chemical problem#

Saprolegnia (an oomycete water mould) infects fish eggs and injured fish, especially in cold water and during handling. Malachite green was the standard cure until it was banned in food fish because it is carcinogenic and genotoxic, and leucomalachite green stays in fish flesh for months. It is still detected in controls, including in fish imported to the EU and in some domestic markets. Formalin is the main legal fallback, but formaldehyde is an IARC Group 1 carcinogen, dangerous to workers, and toxic in effluents.

Self-healing bio-concrete and microbial repair mortars (bacteria producing limestone, microbially induced calcite precipitation, MICP) — instead of epoxy and polyurethane crack injection and some chemical sealants

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: part of epoxy and polyurethane crack repair and chemical grouts · Scope: concrete structures · Evidence: medium

The chemical problem#

Concrete cracks let water and chlorides reach the steel reinforcement, which leads to corrosion and expensive repairs. Crack repair uses epoxy and polyurethane resins. Epoxy is a leading cause of occupational contact dermatitis in construction, and isocyanates cause asthma. Chemical soil grouts have included neurotoxic acrylamide: the Hallandsås tunnel (Sweden, 1997) grout leak poisoned cattle and fish and made workers ill.

Sewage sludge and faecal sludge stabilized biologically — anaerobic digestion, thermophilic co-composting, sludge treatment (drying) reed beds — instead of lime stabilization, landfilling, incineration-only and raw dumping

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: lime stabilization, landfill, raw dumping · Scope: sewage and faecal sludge · Evidence: high (AD, composting), medium (FS business models)

The chemical problem#

Every wastewater plant produces sludge; many small and mid-size plants stabilize it by dosing lime and send it to landfill.
In cities without sewers, faecal sludge from pits and septic tanks is often dumped untreated into drains, rivers or fields.
Landfilled sludge emits methane; incineration without recovery wastes the energy and phosphorus.

Product overview#

Anaerobic digestion (AD) — the standard biological stabilization at larger plants; biogas covers much of the plant’s energy demand (see W01 and EN04).
Thermophilic co-composting — dewatered sludge composted with green waste or crop residues; the hot phase sanitizes.
Sludge treatment (drying) reed beds — planted beds that dewater and mineralize sludge over years with very low energy.
Faecal-sludge treatment plants — drying beds, co-composting, BSF processing and solid-fuel production from FS (see WC02).

Active ingredient / Composition#

AD: mixed anaerobic consortia (hydrolytic, acidogenic, methanogenic) at 35 °C (mesophilic) or 55 °C (thermophilic).
Composting: aerobic thermophilic microbes; bulking agent (wood chips, straw).
Reed beds: Phragmites stands with root-zone microbes.

Key facts#

Parameter	Value
AD	Destroys roughly 40–50 % of sludge volatile solids; biogas typically covers a large share of plant energy
Sanitization	Thermophilic composting (e.g. ≥55 °C for several days) or thermophilic digestion meets pathogen-reduction standards
European practice	Member states differ widely: agriculture, composting, incineration and landfill shares vary from country to country
Faecal sludge	Resource recovery (fuel, compost, protein) can partly finance sanitation services

Advantages#

Biogas makes plants more energy self-sufficient; digestate/compost returns P and organic matter.
No lime purchase or dust; lower greenhouse emissions than landfill.
Reed beds work for small towns with almost no operating cost.
Faecal-sludge plants create a sanitation service market where sewers will not arrive for decades.

Mode of action#

Anaerobic microbes convert sludge organic matter into methane and CO₂, reducing mass and odour.
Thermophilic phases kill pathogens and weed seeds; maturation stabilizes humus.
Reed roots keep beds porous; water leaves by drainage and evapotranspiration while microbes mineralize the residue.

Application#

Situation	Target	Method, timing and specifics
Plants >~20,000 population equivalent	Stabilization + energy	Mesophilic or thermophilic AD; struvite recovery from liquor (NU04)
Small towns	Low-cost dewatering	Sludge treatment reed beds; empty every 8–12 years
Cities with on-site sanitation	Safe FS treatment	Licensed emptying + FS treatment plant (drying, co-composting, BSF, fuel)
Agricultural use	Nutrient return	Only after sanitization and contaminant testing, within national limits

Limitations#

Industrial contaminants (metals, PFAS, pharmaceuticals) can make land application illegal — then incineration with P recovery is the fallback.
AD needs scale, skilled operation and capital.
Faecal-sludge businesses depend on enforced bans on illegal dumping.
Public acceptance of sludge-derived products varies.

Evidence of displacement — D3: proven displacement at scale#

Assessment (hand-reviewed): National (UK): 66% of the 1.6 Mt of sewage sludge produced in 2008 was treated by anaerobic digestion, with biogas used for heat and power (UK government).

Shrimp farming with biofloc technology, Bacillus probiotics and specific-pathogen-free (SPF) broodstock instead of antibiotics and pond chemicals

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: prophylactic antibiotics and pond pesticides · Species: marine shrimp · Evidence: medium–high

The chemical problem#

Shrimp farming suffers from bacterial (Vibrio, including AHPND/EMS) and viral (white spot syndrome virus) diseases. Farmers in Asia and Latin America have used antibiotics prophylactically, including banned chloramphenicol and nitrofurans, which leads to border rejections and residues in food. Pesticides are used to kill carrier crustaceans before stocking. Large water exchange releases nutrient- and drug-loaded effluents.

Soil-biodegradable mulch films (certified to EN 17033: starch/PLA/PBAT/PHA blends) and paper/organic mulches — instead of conventional polyethylene (PE) mulch films that fragment into soil microplastics

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: PE and oxo-degradable mulch films · Scope: vegetable and horticultural production · Evidence: medium–high

The chemical problem#

Mulch films raise yields (soil warming, weed control, water saving), but PE film cannot be fully removed: thin films tear, and the residues accumulate in soil. In China, where mulch covers about 20 million ha, residual film levels of tens to hundreds of kg/ha have been reported in some regions, reducing yields and water infiltration. “Oxo-degradable” films only fragment faster into microplastics, and the EU banned them in 2021 (Directive (EU) 2019/904). Burning retrieved film in fields releases dioxins and soot.

Solid biofuel — pellets, briquettes and residue fuels — instead of coal in boilers and kilns

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: coal/HFO in boilers, straw burning in fields · Scope: pellets, briquettes, co-firing · Evidence: high

The chemical problem#

Coal carries sulfur, mercury and ash into boilers — and every tonne is fossil carbon.
Every harvest leaves straw, husk, shell and stalk residues that are burned in the open (Delhi’s winter smog episodes, Egyptian rice-straw burn-offs) or left to rot to methane.
Heavy fuel oil in dryers and kilns completes the fossil slate for exactly the heat duties residues could serve.

Product overview#

Pellets and briquettes: dried, milled residues extruded to dense, storable, transportable fuel (6 mm industrial pellets, 60–90 mm briquettes); standard fuel specs (EN ISO 17225 classes) exist for trade.
Boiler-side practice: biomass boilers and co-firing (5–30 % share) in existing coal units — the lowest-capex decarbonization step many plants have.
Kiln and dryer duty: briquettes replace coal/HFO in brick kilns, lime, grain and tobacco drying — the classic small-industry conversions of South Asia and Africa.
Circular variants: pellet plants co-located with sugar mills, sawmills and rice processors (the residue arrives at the gate; EN02’s mill logic).

Active ingredient / Composition#

Lignocellulosic biomass: 15–19 MJ/kg dry (≈ half of coal volumetrically, similar per-tonne-C); ash 1–8 % (straw higher — additive/clinker management).
Binders usually none (lignin self-binds under extrusion heat/pressure).

Key facts#

Parameter	Value
Class	Solid biofuel from residues
Energy density	600–700 kg/m³ pellet vs 100–150 kg/m³ loose straw
Seasonality	Residue streams are seasonal — storage and multi-feedstock design decide economics
Climate	Residue carbon is biogenic; open-burning PM2.5 avoided is immediate air-quality value

| Co-firing | 5–20 % share typically needs burner/feed retrofits only |

Advantages#

Waste-to-heat with local fuel security: no import line, price set by collection logistics, not world coal.
Kills the open-burning smog problem by giving the straw a buyer (the same tonne, two problems solved).
Boilers and kilns convert at modest capex; co-firing exists precisely as a bridge technology.
The biomass-waste-to-value cluster (176 active companies in this index) is the regionally strongest supplier base of the whole energy collection.

Mode of action#

Combustion physics unchanged: fixed-carbon burn plus volatiles; the substitution is fuel chemistry (biogenic carbon, near-zero sulfur, low mercury) and logistics (densification makes residue a commodity).

Application#

User	Target	Method, timing and specifics
Food/agro processor	Dryer/boiler fuel	Briquette/pellet burner on own residues first
Coal boiler operator	Partial coal exit	5–20 % co-firing share; ash chemistry monitoring
Brick kiln / lime kiln	Coal exit	Converted zig-zag/FDD kilns on briquettes

| Municipality | Smog control | Straw-purchase pellet plants in burning districts |

Limitations#

Ash and slagging: straw-rich fuels need additives/boiler tuning; chlorine corrosion in some designs.
Seasonality and low bulk density make haulage the cost boss — plants must sit on the residue.
Not a route for the highest-temperature kilns or blast furnaces (Partial verdict there).
Sustainability rules (land, competition with soil carbon return) apply to residue removal rates.

Assessment (hand-reviewed): UK coal down 85% since 2013, partly via conversion to biomass (IEA Bioenergy). Brazil: sugar-mill bagasse power grew from ~100 MW (2000) to ~12.4 GW (2023, ANEEL via ISO); 266 of 422 certified mills export power to the grid.

Spruce bark beetle (Ips typographus) and pine beetle management by early sanitation felling, pheromone monitoring, anti-aggregation pheromones and forest diversification — instead of insecticide-treated trap logs, nets and log-pile spraying

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: insecticide-treated trap logs, netting and log-pile spraying · Scope: spruce and pine forests · Evidence: medium–high

The chemical problem#

Drought and storms trigger massive bark beetle outbreaks. The Moscow region outbreak (2010–2012) after the 2010 drought killed spruce stands over tens of thousands of hectares, and Central Europe (the Czech Republic, Germany) has lost hundreds of millions of m³ since 2018. Insecticide-treated trap logs and log piles also kill the beetle’s natural enemies, and cannot stop landscape-scale outbreaks.

Sugarcane and palm-oil mill residues — vinasse, filter cake (press mud), bagasse, palm oil mill effluent (POME) and empty fruit bunches (EFB) — anaerobically digested, composted and returned to the field instead of raw discharge, open anaerobic lagoons, burning and mineral fertilizer

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: raw discharge, open lagoons, burning, part of mineral fertilizer · Scope: sugar/ethanol mills, palm oil mills · Evidence: high

The chemical problem#

Each litre of cane ethanol leaves 10–15 litres of vinasse, a hot, acidic liquid with a very high organic load and potassium content. Discharged raw, it destroys rivers; applied in excess, it salinizes soils and leaches nitrate.
Palm oil mills treat POME in open anaerobic ponds, which emit large amounts of methane.
Filter cake, bagasse ash, trash and EFB are often dumped or burned, while the same plantations buy mineral K, P and N.

Product overview#

Vinasse fertigation — controlled application on cane fields as a K and water source (Brazilian practice under state limits).
Vinasse biogas — anaerobic digestion before fertigation: methane for power or biomethane, lower COD in the digestate, same nutrients.
Filter cake (press mud) compost — rich in P, Ca and organic matter; composted alone or with vinasse, ash and bagasse into organic fertilizer.
POME biogas — covered lagoons or digesters capture methane for power or grid supply.
EFB/POME compost and biofertilizer — composting EFB with POME into a soil amendment returned to the plantation.
Bagasse — boiler fuel for cogeneration (see EN05), board and paper (Ledesma-type mills), and 2G ethanol.

Active ingredient / Composition#

Vinasse: COD typically tens of g/L, K₂O several g/L, pH ~4–5.
Filter cake: P₂O₅ 1–3 % (dry), Ca, organic matter.
POME: COD tens of g/L; digested POME and EFB compost return N, P, K and organic matter.

Key facts#

Parameter	Value
Vinasse volume	~10–15 L per L ethanol
Fertigation	Replaces much of the mineral potash on cane fields when dosed by soil K and state limits
Vinasse biogas	Technically proven; adoption limited by capital and policy, growing with biomethane markets
POME methane	Capturing lagoon methane is one of the largest single emission cuts available to a palm oil mill

Advantages#

Turns the mill’s biggest pollution liability into energy and fertilizer.
Cuts mineral K and P purchases on the estate.
Biomethane and carbon credits add income (Brazil RenovaBio CBIOs; palm methane-capture credits).
Keeps organic matter and nutrients on the plantation.

Mode of action#

Anaerobic digestion converts organic load to methane, lowering COD and odour; K and P stay in the digestate.
Composting stabilizes filter cake and EFB; returning them closes the nutrient cycle.
Fertigation supplies K and water; soil microbes degrade the remaining organics.

Application#

Mill type	Target	Method, timing and specifics
Cane distillery	Avoid discharge, save K	Vinasse to digester → biomethane/power → digestate fertigation within soil-K limits
Sugar mill	P and organic matter	Filter cake compost (with ash and bagasse) applied in furrow at planting
Palm oil mill	Methane capture	Covered-lagoon or tank digester on POME; gas to engine or grid
Palm plantation	Organic fertilizer	EFB + POME compost/biofertilizer back to the palms

Limitations#

Over-application of vinasse raises soil K and nitrate leaching — dose by soil analysis and legal limits.
Digesters need capital and stable operation (vinasse is seasonal and acidic).
Transport limits how far vinasse and compost can go from the mill.
Some mills still find raw disposal cheaper where enforcement is weak.

Evidence of displacement — D3: proven displacement at scale#

Assessment (hand-reviewed): National (Brazil): fertirrigation has been virtually the only management route for sugarcane vinasse since the mid-1970s (peer-reviewed), after river disposal was banned; biogas use of vinasse remains <2–5% of potential.

Textile wet processing with enzymes — bio-scouring (pectinase), enzymatic desizing (amylase), cellulase "bio-stoning" and laccase denim bleaching, catalase peroxide removal — instead of caustic scouring, pumice stonewashing, potassium permanganate spraying and hypochlorite bleaching

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: caustic scouring, pumice, permanganate and hypochlorite · Scope: textile mills and laundries · Evidence: high

The chemical problem#

Cotton and denim finishing uses large amounts of caustic soda, hypochlorite and potassium permanganate and pumice, and hot water. Sandblasting for “worn” denim caused fatal silicosis in workers (e.g. in Turkey, where it was banned in 2009). Permanganate spraying exposes workers to manganese. Hypochlorite creates chlorinated organic by-products in effluent. Textile wastewater is a major source of industrial water pollution.

Yeast cell-wall (MOS/β-glucan), nucleotide and postbiotic additives instead of the antibiotic-growth-promoter era's ingredient logic

Mon, 01 Jan 0001 00:00:00 +0000

Replaces: AGP-era additive logic (with V01) · Scope: young-animal, aqua, pet feeds · Evidence: medium–high

The chemical problem#

When antibiotic growth promoters left (EU 2006; China 2020 colistin; V01’s timeline), the feed industry had a hole where a cheap “performance insurance” used to sit.
The lazy replacements were like-for-like chemicals — and high-dose pharmacological zinc/copper, which co-select AMR and load soils — the same problem wearing a new vest.
What the biology actually offers is not one substitute molecule but a program: gut architecture, microbiome steering and immune readiness (V-series pattern).

Product overview#

Yeast cell-wall fractions: mannan-oligosaccharides (MOS) block pathogen fimbriae binding; β-(1,3/1,6)-glucans prime innate immunity — both from Saccharomyces brewery/ alcohol streams (a true by-product valorization).
Yeast nucleotides: RNA fractions for rapidly turning gut tissue — prestarter piglet/chick and aqua-fry diets (growth without drugs).
Postbiotics: inactivated yeast and fermentation metabolites (the V01 probiotic concept without live-cell handling).
Program context: works as part of the V01/FD01 stack (enzymes, acids, vaccines, hygiene), not instead of it.

Active ingredient / Composition#

MOS/β-glucan powders standardized to mannose/glucan fractions; nucleotide products ≥5 % RNA-equivalent; dosing 0.5–2 kg/t in prestarter/aqua.

Key facts#

Parameter	Value
Class	Yeast-derived functional ingredients (prebiotic/postbiotic)
Source	Brewery/alcohol yeast streams — residue valorization (EN02 mills!)
Regulatory	Feed ingredients (not drugs) across EU/EAEU/most jurisdictions

| Evidence shape | Consistent small-to-moderate effects; best in challenge/young-animal windows |

Advantages#

Fills the post-AGP shelf with by-product-derived ingredients (brewer’s yeast, ethanol yeast) — circular and cheap at source.
No residues, no withdrawal, no AMR load — export-compliant by construction.
Pairs with FD02 insect meals and FD01 enzymes in the same reformulation exercise.

Mode of action#

MOS mimics mannose-rich gut receptors: type-1 fimbriated E. coli/Salmonella bind the feed particle instead of the enterocyte → pass out.
β-glucans interact with dendritic/Peyer’s-patch receptors (dectin-1 class) tuning innate readiness.
Nucleotides spare de-novo synthesis in fast-turnover gut tissue during weaning/hatch stress.

Application#

Diet	Window	Method, timing and specifics
Piglet prestarter	Weaning	MOS/β-glucan + nucleotides in the V02 program (vaccine, low-protein)
Broiler starter	Hatch window	Yeast fractions in the V01 stack; measure FCR/mortality by flock
Aqua fry/starter	Larval transitions	Nucleotide + β-glucan products (F-series biosecurity)
Petfood	Sensitive/GI lines	Postbiotic positioning (already mainstream)

Limitations#

Honest rating: Partial. Effects are context-dependent (challenge level, base diet, hygiene); these are program components, not magic.
Quality variance between yeast streams; standardized fractions cost more.
Not a substitute for vaccines, hygiene or FD01 precision when those are the gap.

Assessment (hand-reviewed): US medically important antibiotic sales down 38% after the ban (2015–2021) — the old practice fell; the postbiotics’ share is not shown.
