100 MPG Car Guys Getting Into Biofuels
December 1, 2008 (GreenTechMedia) — Lignin can be removed with steam or acid, but that takes energy. Any system that can accomplish that task with less energy will be in high demand in the future. (For some companies doing interesting things with lignin, check out Zeachem and Coskata. After breaking down the plant matter, Zeachem turns cellulose and hemicellulose into acetic acid and cooks the lignin for hydrogen. Later, it all gets combined into ethanol. Coskata meanwhile breaks up plants into synthetic gases.)
