Publisher Summary This chapter focuses on wood saccharification. The wood waste contains 50–65 % carbohydrates in the form of hemicellulose and cellulose. If these carbohydrates are changed into simple sugars, they could be used as a source of carbohydrate feed for cattle, hogs, chickens, and other livestock. These sugars would also be available for use in industrial processes as a reducing material for chemical processes, as a thickening material for dye printing, and as a starting product for the production of various organic substances. This sugar is suitable for fermentation processes for the production of ethyl alcohol, butyl alcohol, acetone, lactic, butyric, acetic, and other acids.
