Gevo and TOTAL Cray Valley partner to develop renewable isoamylene

US-based renewable fuels, biochemicals, and bioprocess developer Gevo Inc., has announced that it has signed a joint development agreement (JDA) with TOTAL Cray Valley, part of France-headed oil, gas, and petrochemical major TOTAL’s Polymers division to upgrade fusel oils from ethanol production into renewable isoamylene.

Isoamylene is predominately used in a diverse set of applications, including resins, pesticides, flavours and fragrances, pharmaceuticals, healthcare products, adhesives, antioxidants, and UV stabilizers.

This collaboration is a spinoff of Gevo’s chemical-based catalytic processes that selectively converts low-value fusel oils, a mixture of alcohols that are byproducts from fermentation processes such as ethanol or isobutanol production, into renewable isoprene, ketones, aldehydes, or olefins. Fusel oils from the ethanol industry alone equate to about 2.5 million tonnes of potential bio-based waste feedstock and this alliance will be another move towards the delivery of low carbon sustainable chemicals, stated Dr Patrick Gruber, CEO of Gevo.
