ABSTRACT:
Methods are described for treating sludge, e.g. biological and/or chemical sludge, with processed cellulose material combined with another material, e.g. a surface active agent, a detergent, a surfactant, a polymer and/or an organic polymer.
Cellulose flakes and methods for making them are disclosed; in one aspect the flakes are useful as animal litter or bedding; in one aspect such used flakes are re-pelletized for use as litter, food or fertilizer. Methods for absorbing, removing, and for cleaning up a first liquid floating on or in a second liquid are disclosed, the method employing absorbent pellets which, in preferred embodiments, have a particular size, density, and configuration. A pellet and a method for making the pellet are disclosed for cleaning up a first liquid floating on or in a second liquid; and a method for making pellets for absorbing a combustible material to produce fuel pellets. A method for producing fuel pellets is disclosed. In one aspect such materials are disclosed with surface active agent therein and/or thereon and methods for producing such material.
