WASTE PAPER AS A PULP SUBSTITUTE IN NEWSPRINT

Possible economic advantages for newsprint mills by the use of waste paper are discussed. The disadvantages, such as wide price fluctuation, contaminants and variation in quality are pointed out. Conditions can exist where the use of waste paper could prove to be profitable, as a substitute for unbleached sulfite, or a pulp substitute when the productivity of the paper machines outruns that of the pulp mill. To be economically feasible, low-cost grades of waste paper in abundant supply must be used. New methods of processing to remove contaminants are suggested. The plant must be large enough to be profitable. Flow charts of three waste paper recycling systems are included.
