The bamboo bioeconomy — engineered bamboo building materials (strand-woven timber, panels, framing and composite decking) from one of the fastest-growing plants on earth — led by MOSO (Netherlands), BamCore and Cali Bamboo (USA) and Dasso (China).

Industrial binders from soy protein, kraft lignin and mussel-inspired catechol polymers that replace formaldehyde resins in wood panels, packaging and underwater repair.

Bio-antiflammables replace halogenated flame retardants (brominated, chlorinated) — restricted under EU REACH and displaced by regulatory pressure in the US and EU — with phosphorus chemistry from renewable carbon, lignin-derived platforms, and bio-derived wood-fire-inhibitor formulations. Clariant's Exolit™ OP Terra achieves 100% renewable carbon content via mass-balance certification while retaining the halogen-free DEPAL (aluminum diethylphosphinate) chemistry's UL 94 V-0 rating even after recycling. Vertoro's Goldilocks® platform (Geleen, Netherlands, founded 2017) converts agricultural and woody residue lignin into flame-retardant building blocks at TRL 6, part of the EU Horizon BIOSAFIRE consortium (22 partners, ~80% biobased content target across naval, railway, home-appliance and wood-coating sectors). CitroTech (Oceanside, CA, NYSE American: CITR) formed a 50/50 joint venture with Hexion in April 2026 to deploy its patented fire-retardant chemistry — the only formulation recognized under the EPA's Safer Choice program — across the North American lumber and engineered-wood industry, replacing borate-based inhibitors. A large and active 2026 academic literature base (phytic acid, lignin-tannin conjugates, boron chemistry) signals a research pipeline still substantially ahead of its commercialization, making this an earlier-stage Industry than mature bio-based polymer or plasticizer categories.

Renewable hydroxyl-functional building blocks from vegetable oils, lignin and cashew nutshell liquid that replace petrochemical polyols and isocyanates in flexible foams, coatings, TPU and elastomers — closing the carbon loop of a >$90 bn polyurethane market.

Bio-bitumen and bio-asphalt replace or extend petroleum bitumen with plant-oil and lignocellulosic-biomass binders and rejuvenators. SoyLei's SIP-1111 Rejuv (sub-epoxidized soybean oil, SESO) completed AASHTO's Asphalt Mixture Recycling Agent DataMine pathway (report AMRA-2025-02-003, May 2026), enabling 45%+ reclaimed-asphalt-pavement (RAP) mixes; Sripath Technologies' ReLIXER/PGXpand/ButaPhalt suite is deployed on high-RAP projects in the US, Australia, Ireland and elsewhere, including a 100%-RAP New York City project. Colas's Vegecol and Vegeroad Bitumen (majority-plant-oil binders) cut asphalt carbon footprint up to 70% and CO2 emissions up to 30% versus conventional bitumen, rolled out across France, Denmark and other European markets. In India, CSIR-CRRI and CSIR-IIP transferred an indigenous bio-bitumen technology (pyrolysis of rice-straw and other farm residue into bio-oil, blended 20-30% with conventional bitumen) for national-highway adoption, targeting India's roughly 50% bitumen import dependence.

Bio-FDM filaments run on NatureWorks' Ingeo PLA resin backbone — the feedstock behind most toughened PLA+ and specialty filament brands — layered with region-specific biodegradability engineering: colorFabb's fermentation-derived allPHA (fully compostable, no microplastics) in the Netherlands, Extrudr's DIN EN ISO 14855-certified GreenTEC PRO in Austria, and eSUN's high-volume toughened/metallic/wood-grain PLA+ lines riding China's plastic-ban-driven PLA capacity expansion (365,000 t in 2025, forecast 426,000 t in 2026).

Bio-impregnation for wood displaces chromated, solvent-based and petrochemical wood preservatives and finishes with renewable-feedstock chemistry: the Netherlands' Accsys Technologies acetylates solid wood and wood elements with acetic anhydride to produce Accoya and Tricoya, while Denmark's WOCA and Germany's Osmo deep-impregnate exterior and interior wood with low-VOC natural oils. Canada's Sansin Corporation finishes both traditional and acetylated wood with water-borne natural-oil stains, and Vermont's Vermont Natural Coatings replaces solvent-based polyurethane with PolyWhey, a patented finish built on whey protein, a dairy-processing byproduct.

Bio-printing filaments (medical) are bioresorbable polymer materials extruded into filament or fiber form for 3D-printed medical devices that dissolve in the body as natural tissue regrows: Singapore's Osteopore 3D-prints polycaprolactone-tricalcium-phosphate bone scaffolds, clinically used for critical-sized bone defects and now expanding into China. Germany's Evonik and the Netherlands' Corbion supply FDA-approved, GMP-grade bioresorbable polymer feedstock (RESOMER and PURASORB) to device makers, while South Carolina's Poly-Med vertically integrates polymer synthesis, filament extrusion and finished absorbable-device manufacturing under one roof.

Two distinct, honestly-different routes displace virgin fossil carbon black in rubber and tires: a genuinely bio-based one, where Canada's FPInnovations converts kraft-pulping black liquor (lignin) into a carbonaceous rubber filler via hydrothermal carbonization, restoring over 60% of mechanical strength when carbon black is cut by 15%; and a circular, tire-derived one — not biological in origin but displacing the same virgin fossil-carbon-black demand — where Cabot Corporation's EVOLVE and Orion Engineered Carbons' ECORAX Circular convert end-of-life-tire pyrolysis oil into ISCC PLUS mass-balance-certified reinforcing carbon, Birla Carbon's Continua turns tire-pyrolysis solids directly into finished carbonaceous material, and India's Epsilon Carbon sells Terrablack, a recovered-carbon-black line claiming 40-50% lower global warming potential than virgin carbon black.
