Jean Pierre Corbat,Uwe L. Pawlowskid except for cellulose. Hemicellulose has not yet been utilized. Lignin, which is obtained as a by-product of the pulping industry, is mostly burnt as fuel and only increases the amount of carbon dioxide in the environment, although lignin is one of the most useful natural resources.
