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.
