AFYREN NEOXY Bio-based Organic Acids

AFYREN SAS is a French industrial biotechnology company registered in Clermont-Ferrand, co-founded by Nicolas Sordet and Jeremy Pessiot. It produces bio-based organic acids that substitute for petroleum-derived molecules used in animal nutrition, human nutrition, lubricants, flavours and fragrances, materials and life sciences.

The AFYNERIE process uses anaerobic fermentation by natural microorganisms on non-food biomass and yields seven products in one run. The AFYREN NEOXY plant at the CHEMESIS platform in Carling Saint-Avold, Moselle, is rated at 16 kt per year of seven organic acids from sugar beet co-products, and the company also sells a potassium-rich fertilizer co-product.

• Acid portfolio: acetic, propionic, butyric, isobutyric, valeric, isovaleric and caproic acids.
• AFYNERIE fermentation: anaerobic fermentation by natural microbial communities.
• Non-food feedstock: biomass and co-products that do not compete with human food.
• Industrial plant: AFYREN NEOXY with 16 kt per year capacity in France.
• Fertilizer co-product: potassium-rich fertilizer usable in organic farming.
• Target sectors: nutrition, lubricants, fragrances, materials science and life sciences.

Animal feed and premix producers in Vietnam can evaluate bio-based propionic and butyric acids as feed additives. Flavour, fragrance and cosmetic manufacturers can source natural-origin acids. Lubricant and technical fluid blenders can test bio-based acids as inputs.

Seven bio-based acids come from a single fermentation process, giving buyers one supplier for a family of molecules. Feedstock is non-food biomass, so it does not compete with food. The model targets zero industrial waste, with a potassium fertilizer co-product. The page cites 11 patent families.

Buyers of preservatives, feed additives and specialty chemicals seek bio-based substitutes for petrochemical acids to meet sustainability targets. The company says it is studying capacity in Asia and America depending on biomass availability, which fits Southeast Asia's large agro-industrial residue base.

Registered as AFYREN SAS at 9-11 rue Gutenberg, Clermont-Ferrand, France. B Corp certification announced June 2026 and a 3 million EUR grant from the European Just Transition Fund in April 2026. AFYREN NEOXY is a partnership with the SPI Bpifrance fund.
