The principal uses, other than for fuel, for the wastes from the sawmill and woodworking industries are found in the following chemical industries: Destructive distillation, the manufacture of pulp, paper, and building boards, and those industries consuming large quantities of wood flour, principally linoleum, plastics, and explosives. The technical aspects of this waste utilization have been so satisfactorily worked out that a project of this sort may be evaluated almost entirely from the economic side. Competition from other raw materials, together with certain economic factors, requires that all of these operations be based on an ample, well-located, and relatively long-lived supply of waste wood. In many of these processes the waste wood must be separated either as to size or as to variety, although in some cases similar varieties may be processed together.
