  • Patent number: 5215041
    Abstract: The invention relates to a novel method for the manufacture of animal litter using filler materials and additional materials that react with liquid. These filler materials are obtained from a fraction of domestic, industrial and other similar waste and/or paper slurry. The fraction obtained from the waste is pulverized and mixed with the additional materials, the mixture is adjusted to a specific moisture content, subsequently granulated, and the resulting granules with a predetermined particle size are separated.The animal litter manufactured according to the invention ensures a high degree of odor retention, has high absorbing power and a low apparent density.

  • Patent number: 5100066
    Abstract: The invention relates to a method for processing domestic, industrial and other like waste with the production of a cellulose material in which the waste material is subjected to pre-comminution, magnetic separation, air-classification and fractionating. It is primarily characterized in that the light fraction consisting of paper, textiles and plastics material separated in the air-classification is passed to a washing station and the washed air-floatable materials passed into a pulper, the ballast substances are removed following the treatment in the pulper by means of screening and the cellulose particles distributed in the water that pass the screen are introduced, directly or after pressing out the water, to a paper mill that may be associated with the plant, or the pressed cellulose particles are dried and recovered as powder.

  • Patent number: 4815668
    Abstract: A process for working up household, industrial and other similar waste for the recovery of a fibrous and/or granulated material, in which the waste material is subjected to preliminary comminution, magnetic separation, classification, drying and fractionation, wherein the light fraction resulting from the classification carried out after the magnetic separation is subjected to secondary comminution by cutting, and the heavy fraction to a predominantly granulating secondary comminution and thereafter both comminution products are recombined, dried and fractionated into fibrous matter and granulated material, is to be simplified, and in particular the costs reduced. This is achieved in that before the secondary cutting comminution appliance at least one part stream or the whole stream of the light fraction is diverted and fed directly and/or after comminution in a further comminution unit to further utlization. A device for carrying out the method is also proposed.
