1. A method for making free flowing incineratable absorbent granules comprising:
- (a) mixing cellulosic plant fibers and a non-self associating fiber or non-film forming particulate;
(b) agglomerating the mixed plant fibers and non-self associating fibers or non-film forming particulates into agglomerates;
(c) densifying the agglomerates into granules;
(d) compacting the plant fibers on the surface of the granules providing a smooth free flowing granule; and
(e) drying the formed granules which granules have an oil Surface Residue Value of less than 0.5 grams, an average density of from about 0.15 to 0.5 grams per cubic centimeter and are free flowing.

Abstract
There is provided a cellulosic-based fiber granule with added non self-associating particulates or fibers. The resulting granule is free-flowing with a densified outer surface and is capable of removing substantially all oil or other fluids from a flat surface such as a floor. The granule is also capable of being incinerated by being formed substantially of organic materials. Cellulosic plant fibers form at least 10 percent up to 99 percent of the granule. There is also provided a method for forming the incineratable absorbent, free-flowing granules.

25. A method of removing a fluid from a surface comprising
providing free flowing incineratable absorbent granules comprising cellulosic plant fibers and non-self associating fibers or particulates, having a density of from about 0.15 to 0.5 grams per cubic centimeter spreading the absorbent granules over a fluid containing surface for a time sufficient to absorb substantially all the fluid, wherein the granules have an oil Surface Residue Value of less than 0.5 grams removing the absorbent granule from the surface to provide a substantially fluid-free surface.
