High-value chemicals produced from ethanol feedstocks could boost biorefinery economics

Biorefineries developed to produce ethanol from cellulose sources such as trees and fast-growing plants could get a significant economic boost from the sale of high-value chemicals – such as vanillin flavoring – that could be generated from the same feedstock. Revenue from these "side stream" chemicals could help make ethanol produced by biorefineries cost competitive with traditional fossil fuels.
