HANDLING OF WASTE MATERIAL Refuse, such as domestic refuse, containing inorganic and organic material is treated to separate off the inorganic material, after which the organic material is assimilated in a digestor by a microorganism to produce a combustible gas, and a dilute slurry emerging from the digestor is concentrated to recover a concentrated slurry or cake of mainly organic content, which can be utilised. |
