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.

De préférence, il s'agit de fibres recyclées provenant de diverses sources telles que boîtes en carton ondulé, vieux journaux, déchets mélangés de bureaux et analogues. L'invention concerne également des produits en papier découlant des fibres traitées, ainsi que de leurs procédés de fabrication.
