    Abstract: Compositions and methods for inhibiting the deposition of organic contaminants from pulp on the surfaces of pulp and papermaking systems are disclosed. The composition is a combination of a polyvinyl alcohol having 50 to 100 % hydrolysis and a high molecular weight gelatin having a molecular weight of about 100,000 or higher and is added to the pulp or sprayed onto the surfaces of the pulp and papermaking system. In a preferred embodiment, synergism is demonstrated by an 8 to 1 weight ratio of polyvinyl alcohol to high molecular weight gelatin.

    Abstract: Methods to control organic contaminants in fibers are described. One method involves contacting the fibers with a composition containing at least one esterase or lipase or both for a sufficient time and in a sufficient amount to control the organic contaminants present in the fibers. Preferably, the fibers are recycled fibers originating from a variety of sources such as old corrugated containers, old newsprint, mixed office waste, and the like. Resulting paper products formed from the processed fibers are also described as well as methods to make them.
