Bio-based polymers for durable products — from monomer to market.
Follow PLA, PHA and PEF — and the new chemistry around them — through verified structures, cited background and a monthly, source-checked tracker. Discovery and evidence are always labelled apart.

Three focus routes, six further families and a scope-review watchlist.
Polylactide from fermentation-derived lactic acid, including stereocomplex PLA and PLA blends.
Polyhydroxyalkanoates made inside bacterial cells, from PHB to copolymers such as PHBV and PHBHHx.
Poly(ethylene furanoate) from 2,5-furandicarboxylic acid and ethylene glycol, and its furanoate relatives.
Bio-based PBS/PBSA, bio-content PBAT, isosorbide polyesters and chemically recyclable lactone polymers.
PA11 from castor oil, PA 5.X from bio-cadaverine, and long-chain polyamides from plant-oil diacids.
Polycarbonates from the sugar-derived diol isosorbide, and from epoxide/CO₂ ring-opening copolymerisation.
Bio-based polyols and isocyanates, and non-isocyanate polyurethanes from cyclic carbonates and amines.
Epoxies from vanillin and plant oils, itaconic and furan networks, cardanol resins and dynamic covalent networks.
Materials made by modifying polymers that nature already builds - shown by representative units only.
Bio-PE/PP/PET/PA, mass-balance attributed products and biofilled fossil polymers - tracked, never counted as new bio-based polymers.
Checked developments and machine-triaged leads are separate evidence categories. How we verify →
Origin, performance and end of life are separate questions.
The EU Packaging and Packaging Waste Regulation (EU) 2025/40 asks the Commission for a review of bio-based plastic packaging: the Commission should publish, no later than 3 years after the entry into force of this Regulation, a review of the state of technological development and environmental performance of biobased plastic packaging
— European Parliament and Council, Regulation (EU) 2025/40 (OJ L, 2025/40, 22.1.2025), retrieved 20 Oct 2026
The Commission's policy framework on bio-based, biodegradable and compostable plastics (COM(2022) 682) warns on claim accounting: attributing a share to end-products through mass balance accounting is a method which is not considered suitable for confirming the actual share of biobased content
— European Commission, COM(2022) 682 final, retrieved 20 Oct 2026
Bio-based origin does not settle end of life: Bio-based plastics are fully or partially made from biological resources, rather than fossil raw materials. They are not necessarily biodegradable or compostable.
— European Commission, DG Environment, Commission web page, retrieved 20 Oct 2026 A footprint claim needs its functional unit, boundary and comparator before it means anything [Walker 2020; Spierling 2018].
Bio-based polymers must still meet the stiffness, toughness, heat and barrier demands of the parts they replace — and do it at scale. PLA's high strength but low toughness is the textbook case [Nagarajan 2016]. This site tracks progress on those constraints rather than headline claims.
