Braskem Joins Pact Pursuing Bioisoprene
by Michael McCoy

Volume 92, Issue 37
Brazil’s Braskem is joining an existing collaboration between the biobased chemical company Amyris and the tire maker Michelin to commercialize biomass-derived isoprene. A key synthetic rubber ingredient, isoprene is now obtained as a by-product of ethylene production, but output is decreasing as companies switch to lighter feedstocks. With its ethanol-derived polyethylene, Braskem considers itself to be the world’s leading biopolymers producer. DuPont and Goodyear have run a competing bioisoprene venture since 2008.
