ABSTRACT:
Domestic refuse containing inorganic and organic material is treated to separate off the inorganic material, after which the organic material, with sewage sludge, is assimilated in a digestor by a microorganism to produce a combustible gas, and a dilute slurry emerging from the digestor is dewatered to recover a self-binding concentrated slurry or cake containing long fibres suitable for use in the production of boards, paper, or fuel, for instance. The more dilute slurry which results from the dewatering is concentrated, and is then useful as a soil conditioner or animal feedstuff.
