ABSTRACT:
A method of making sanitary paper products from newspapers. The method includes the steps of: (a) pulping newspapers in water with agitation to produce a pulp slurry, the fiber in the newspapers having an oil content ranging from about 0.025% to about 2.0%, by weight, and the slurry having a consistency between about 3% and about 18% and a pH below about 8.0; (b) adding a surfactant to the pulp slurry and maintaining the pulp slurry at a temperature above about 100.degree. F. for at least 15 minutes such that a substantial quantity of the oil in the old newspaper is retained; (c) increasing the consistency of the slurry to between about 3.5% and about 18%; and (d) using the treated pulp as a source of fibers in a paper making process to produce sanitary paper products.
