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.
Abstract translation: 描述了控制纤维中有机污染物的方法。 一种方法包括使纤维与含有至少一种酯酶或脂肪酶或两者的组合物接触足够的时间和足够的量以控制存在于纤维中的有机污染物。 优选地，纤维是源自各种来源的再循环纤维，例如旧的瓦楞纸箱，旧的新闻纸，混合的办公室废物等。 还描述了由加工纤维形成的所得纸制品以及制造它们的方法。

Abstract: Disclosed is a method of improving sizing in a paper or paper board product comprising combining a papermaking sludge with an enzyme composition to form an enzyme-treated sludge; combining said enzyme treated sludge with a papermaking pulp to form a treated pulp, forming a paper or paperboard product from said treated pulp, wherein said product has improved sizing compared to the sizing of an identical paper or paperboard product but not having the sludge treated with enzyme composition, wherein said enzyme composition comprises at least one polyamide oligomer and at least one cellulitic enzyme or alternatively a protease, esterase or a lipase.
