  • Patent number: 5909718
    Abstract: A paper based particulate absorbent material and method of manufacture using shredded paper along with water and a binder mixture. In the first step of the process the waste paper is subjected to a size reduction treatment. In the second step, the paper is mixed with water and optionally a binder. The material exits the mixing apparatus which can be fully dried to produce a particulate absorbent material. This material can be used for litter material, box packing material, caulking filler and floor sweep. The product can be made to be similar in appearance to commercially available litter materials but is lighter, dust-free, biodegradable and extremely absorbent. The packing material can be made to bend but not crease. Further, the product is extremely economical since it is made out of waste paper.
