Afyren Neoxy has opened its first large-scale biorefinery at Carling Saint-Avold in north-eastern France on time and within budget. Construction began in December 2020 and commissioning took place in June.

The plant uses fermentation technology based on natural microorganisms, followed by extraction and purification steps to make seven 100% biobased organic acids from sugar beet. This is sourced in the immediate region, where it is a common crop.
