METHOD FOR PRODUCING HUMUS FROM AN AMMONIA-EMISSION-FREE EMISSION FROM A WASTE MATERIAL IN THE FORM OF SLURRY OR COMMUNAL SEWAGE SLUDGE

摘要

Process for the elimination of waste materials such as semi-liquid manures or domestic sewage sludges by preparing, without emission of ammonia, solid, stable and sterile products for use as humus, filter humus, natural fertiliser, soil improver or storable fuel, by mixing in biological waste materials such as long grass, straw or sawdust, in a specific formula and at a specific moisture level by means of a mobile mixing plant and discharging the mixture through a screw conveyor to a heap of material. This heap has a height of approximately 3.00 m and any desired width and length and is enclosed in a type of biological reactor made of, for example, sawdust, and must not be turned. After approximately 4-6 months, the waste materials have been degraded and converted in such a manner that a peat-like end product will have formed which is highly suitable as a soil improver or fuel.
