ABSTRACT:
A method of reducing the number or amount of chemical additives normally incorporated into paper pulp furnish before transferring the latter to the continuous wire mesh of a papermaking machine in the manufacture of paper sheet involves the use of a hydrolyzed proteinaceous foam which does not appreciably affect the degree of sizing of the finished paper sheet. The use of such foam in paper manufacture can render unnecessary the chemical treatment of effluent from the papermaking machine which is normally required to avoid environmental pollution.
