ABSTRACT:
A method for making an animal bedding fiber product, the method includes providing fiber from paper sludge, formulating the fiber in a mixture including a first desiccant agent including ash, so as to form a friable aggregate. Further, a fiber product including at least one short paper fiber from a secondary fiber, one or more inorganic fillers including kaolin clay; and a first desiccant agent including ash. Further still, a heatless process for making a fiber product including providing fiber from paper sludge, formulating the fiber in a non-active heat generating mixture including a first desiccant agent including ash, so as to form a waste fiber product.
