Zeachem

Description: 

ZeaChem's innovative process was designed for high yield. The company is pioneering biorefinery technology using combinations of biochemical and thermochemical processing steps. The biochemical processing step converts fermentable sugars in the cellulosic biomass into acetate, which is then recovered from the broth as an ester. The thermochemical processing step converts lignin and other non-fermentable materials in the cellulosic biomass into hydrogen. By combining these two streams in a hydrogenolysis reaction, ZeaChem produces ethanol. Unlike other processes, the Zeachem process uses all fractions of the plant - cellulose, hemicellulose, and lignin, giving it much higher yield.
