ABSTRACT:
A method of making an absorbent granulate of paper, with or without additives, includes mechanically comminuting paper into irregular and/or strip-shaped fragments, crumpling and interlacing the fragments with attendant development of internal spaces (cavities) in the interlaced and crumpled fragments, rough pressing the interlaced and crumpled fragments into prepressed formations (e.g., into tubes having a diameter of up to or even in excess of 10 mm), and converting the prepresssed formations into particles, particularly into granules or pellets. The crumpling and interlacing step can include agitating the fragments in one or more streams of a gaseous fluid and/or kneading the fragments. The additives can be admixed during at least one of the comminuting, crumpling and interlacing, rough pressing and converting steps and can include substances which reduce the specific weight of granules, substances which alter the magnetic and/or electrostatic properties of the mixture of fragments and additives, aromatic substances, deodorants, disinfectants or materials which influence the wettability of paper. Up to 20 percent by weight of water can be added to paper in the course of at least one of the comminuting, crumpling and interlacing, rough pressing and converting steps. The granulate can be used as litter or as an oil binding material.
