U Wisc. scientists develop new method to convert lignin to simple chemicals under mild conditions

Green Car Congress

Researchers at the University of Wisconsin have disclosed a new method to convert lignin, an important component of biomass waste, into simple chemicals. Lignin is the only large volume renewable feedstock that contains aromatics. We need to find an economical way to convert lignin to value-added materials.
