Economic Aspects of Papermaking Fibrous Raw Materials

Complex economic forces determine the particular kind of fiber which is used for any particular purpose. Coniferous wood provides 91 percent of the fiber used in papermaking. The northern hemisphere is the most accessible source of coniferous wood. About 3 percent of the U.S. supply of timber grows and is moved annually, of which 10 percent is in pulpwood, 10 percent is lost through fire, and 80 percent is consumed by other. wood-using industries. The wood pulp industry has developed where pulpwood is cheap and plentiful. Forty-seven percent of pulp produced is now sulphate pulp from southern pine. Projection of future pulpwood requirements indicates that the U.S. can meet its 1960 requirements without increasing imports. There is a growing tendency toward integrated forestry operations, coupled with a movement toward industry conservation of forest resources because of the high capital investment in pulp and paper mills.
