The non-woven web of the present invention is comprised of recycled cellulose fiber and untreated Clarifies Sludge, and optionally, recycled glass fiber. Unlike uses of reclaimed Clarifies Sludge whereby the material has been treated in some fashion to improve its quality, the non-woven web of the present invention utilizes untreated Clarifier Sludge. The Clarifies Sludge of the present invention is dry enough to handle, and in one example varies between about 30% and about 45% solids. The Clarifier Sludge can be added to web-forming equipment (e.g., papermaking equipment) either in a waste paper disintegrator or into a recycling apparatus (e.g., broke pulper) whose output is metered into a refiner tank of the web-forming equipment. In an embodiment utilizing a broke pulper for introduction of the Clarifier Sludge, the broke pulper is filled with clarifier sludge and water to a consistency of about 3.5% solids.
