Abstract
An oil and grease absorbent material formed from treated paper sludge or other fibrous slurries and a method of treating the slurry to form the material which includes the physical properties of clay absorbents. The method involves the addition of materials to the shredded slurry to control color, bacteria, fungi, and density. A quantity of lipophyllic ray cells are added to the slurry to increase oil absorbency. The slurry is then formed into granules and dried before packaging.
Claims16
A filler material for use as an oil and grease absorbent, said filler material comprising plant fiber granules, said granules including ray cells of at least 10% by weight of said granules.

- (a) providing a quantity of a plant fiber slurry;
- (b) adding ray cells at a quantity equal to or greater than 10% by weight of said slurry to form a mixture;
- (c) adjusting the moisture content of said mixture to allow fiber size reduction;
- and
- (d) reducing the fiber size of said mixture;
- (e) forming said mixture into granules;
- and
