Abstract: Methods of making paper or paperboard are described. In one method, at least one cellulytic enzyme composition and at least one cationic polymer composition are introduced to a paper maki ng pulp at about the same time to form a treated pulp. The pulp may also be treated with at least one cationic starch. The resultin g pulp is formed into a sheet of pulp. Other paper making processes are also described. A paper making apparatus is also described for carrying out the methods. Paper and paperboard made according to the methods are also described.

Abstract: A method of de-inking non-impact printed paper comprises contacting repulped paper with a formulation comprised of a derivatized ethylene oxide/propylene oxide polymer and a petroleum hydrocarbon distillate. The process separates the ink from the paper and agglomerates the separated ink into particles of a size sufficient that they can be efficiently removed from the paper fibers.
