Solvay and Trillium Renewable Chemicals have signed a letter of intent to develop the supply chain for bio-based acrylonitrile (bio-ACN).

Trillium will supply Solvay with bio-ACN and Solvay will evaluate bio-ACN for more sustainable carbon fiber manufacturing The aim of this partnership is to produce carbon fiber for use in aerospace, automotive, energy, and consumer goods, the companies say.

Acrylonitrile is a chemical intermediate usually made from petroleum-based feedstocks such as propylene and is the primary raw material used in the production of carbon fiber. Trillium’s Bio-ACN process delivers acrylonitrile from plant-based feedstocks such as glycerol with a lower carbon footprint, Solvay said.

“Trillium’s bio-ACN process technology enables bio-carbon fiber,” said Corey Tyree, CEO of Trillium. “We are excited to continue our partnership with Solvay, who have supported the bio-ACN process technology development since 2014.”
