Gevo process offers ‘low-cost’ isoprene from waste bio-oils

Englewood, Colombia – Renewable fuels and chemicals manufacturer Gevo Inc. has developed a “breakthrough” catalytic process that transforms waste by-product into isoprene.

The process involves using chemical-based catalysts to convert low-value, fusel oils into isoprene, said Gevo’s 28 Jan announcement.
