AFYREN is a France-based industrial biotechnology company focused on producing bio-based carboxylic acids from renewable, non-food biomass. Using natural fermentation, it manufactures a range of short-chain acids—including acetic, propionic, butyric, isobutyric, valeric, isovaleric, and caproic—that are typically derived from petrochemical routes.
The company’s process uses agricultural co-products such as sugar-beet residues and natural microorganisms to convert biomass into high-purity ingredients. Designed around circular-economy principles, the technology aims to lower greenhouse-gas emissions and minimize waste, with a mineral-rich fertilizer produced as a co-product.
AFYREN supplies bio-based ingredients and intermediates for markets with stringent quality requirements, including food and animal nutrition, flavors and fragrances, cosmetics and personal care, and specialty chemicals. It operates an industrial-scale production site in eastern France to serve customers in Europe and beyond.

Renewed partnership extends supply of French-made, bio-based potassium-rich fertilizer for high-value crop formulations, strengthening local potassium availability.
Plant passed 1,000 t of bio-based acids; capacity reached 30–40% after June works; process held up during heat/water stress; aims to double NEOXY H2 2026 revenue vs H1.
One-month June shutdown completed on time and on budget; €6M downstream upgrades, 20,000 working hours, production restarted and H2 2026 acceleration expected.
NEOXY plant generated ~€1M in early 2026, production in the hundreds of tonnes, capacity at 20%, and a June 2026 shutdown for reliability and optimisation.
The plant completed construction, began production, and delivered initial biobased acid lots. It aims for full capacity by 2023, targeting 16,000 tons annually and €35M in sales.
The financing will fund the first plant's design and development, advancing bio-based acid production technology for markets like cosmetics, nutrition, and fine chemicals.
