Old process
Conventional mineral NPK fertilizers, primarily produced via the energy-intensive Haber-Bosch process (for nitrogen) and mined phosphate rock.
→
New practice
Use of digestate, insect frass, and other bio-based fertilizers (BBFs) derived from organic waste streams (manure, food waste, sludge) as substitutes for mineral NPK fertilizers.

Caveats
While digestate and other bio-based fertilizers have the technical potential to replace significant portions of mineral fertilizers, actual commercial displacement is currently limited by logistical costs, regulatory constraints (such as the EU Nitrates Directive), and the need for further policy support to scale adoption. Most evidence refers to technical potential or field-trial performance rather than widespread market-level displacement.

2026-10-06
Current European digestate production has the technical potential to replace more than 16% of mineral nitrogen fertilizers, up to 30% of phosphorus, and 10% of potassium demand in European agriculture.
“Such production volumes could technically replace more than 16% of mineral nitrogen fertilisers used in European agriculture, alongside up to 30% of phosphorus and 10% of potassium demand.”

Insect frass and various bio-based fertilizers have demonstrated mineral fertilizer replacement values (MFRVs) often exceeding 100% in field and pot trials, indicating they can effectively substitute for mineral P fertilizers.
“In conclusion, most tested BBFs have the potential to replace conventional inorganic P fertilisers across a range of European soils and climate.”

Rising synthetic fertilizer prices linked to natural gas costs have driven increased interest in bio-based fertilizers as a cost-effective alternative.
“Recent supply chain disruptions and limited access to natural gas have led to a surge in synthetic fertiliser prices, dramatically increasing production costs and food prices (Alexander et al., 2023). These events, combined with the depletion of fossil-fuel reserves (Welsby et al., 2021), have spurred a renewed …”

Details

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#

  1. Digestate — the residue of anaerobic digestion (biogas). Liquid fraction is rich in ammonium N; solid fraction carries P and organic matter.
  2. Compost and vermicompost — aerobically stabilized organic matter; slow-release N, P, K plus humus.
  3. Insect frass — black soldier fly or cricket excrement plus exuviae (chitin); a fertilizer with biostimulant properties.
  4. 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#

ProductTypical nutrients (fresh or as sold)Notes
Liquid digestate2–6 kg NH₄-N/m³, P and KHigh ammonia-loss risk at spreading (use injection or trailing hose)
Compost1–2 % N (mostly organic), 0.5–1 % P₂O₅Slow release; rebuilds organic carbon
Insect frass~2–4 % N, P, K, chitinLegal as a fertilizer after heat treatment (EU: 70 °C, 60 min)
Organo-mineral granulee.g. 40 % organic matter + 4–10 % N/P₂O₅Example in the index: 40 % OM, 6 % humic+fulvic, 1.5 % N, 4 % P₂O₅

Key facts#

ParameterValue
Long-term effectOrganic amendments raise soil organic carbon, microbial biomass and aggregate stability over years
YieldOrganic-only systems yield on average less than conventional (gap depends on crop and N supply); combined organic + mineral programmes close most of the gap
RegulationEU FPR 2019/1009 component material categories for compost (CMC 3) and digestate (CMC 4, 5); national rules for sludge-derived products
LogisticsLow 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#

SituationTargetMethod, timing and specifics
Arable land near biogas plantsN and P supplyLiquid 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, orchardsOrganic matterCompost 10–30 t/ha before planting; reduce base NPK accordingly
Field crops far from waste sourcesConvenienceOrgano-mineral granules through standard spreaders
Nurseries, high-value horticultureFertility plus biostimulationVermicompost 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.
  • Bulky products: economics fall quickly with transport distance.

Government funding signals#

Scanned 2026-10-01 (OpenAIRE + NSF); candidates reviewed by hand.

Signal: Moderate. Frass is being funded as a product: the Swedish Energy Agency project P2022-00723 “Frass as a biostimulant for large-scale cultivation” (SEK 3.0 M). The wider organic-amendment field is funded mostly through national agricultural programmes, which these two sources cover poorly.

Bioeconomy value#

Every biogas plant, composting site and insect farm in this index also makes a fertilizer. Selling it as a quality-assured product, not disposing of it as a residue, improves the economics of the waste plant and cuts the farm’s mineral NPK bill.
