ABSTRACT:
Methods to control organic contaminants in fibers are described. One method involves contacting the fibers with a composition containing water-soluble cellulose derivative and ester hydrolyzing enzyme, for a sufficient time and in a sufficient amount to control the organic contaminants present in the fibers. This method is effective to reduce stickies in paper mill furnish formed with recycled fibers. A method for pitch control in paper mill furnish formed with virgin fibers is also provided by the additional inclusion of lipoxygenase in the composition. Resulting paper products formed from the processed fibers are also described as well as methods to make them.
