Wood (composed of cellulose, lignin and hemicelluloses) is the main raw material used to produce paper cellulosic fibers used for the production of paper and board. Worldwide, the production of cellulosic fibers is about 150 million tons, using about 310 millions tons of wood. The main process used to produce cellulosic fibers is an alkaline process called the Kraft process. These mills look very much like biorefineries : the cellulose is isolated almost pure in...
