<p>The process of invention is characterized in that the 100 mass parts of meat industry waste products is optionally mixed with 15 to 35 mass parts of watery cattle or pig dung and 3 to 5 mass parts of mucilage of vegetable oil industry and 0.25 to 0.75 mass parts of copper (II) sulfate solution. The mixture is heat-treated and degreased in two stages then 0.2 to 0.7 mass parts of solution of a mixture of carbacrole and thymol or 0.2 to 0.8 mass parts of solution of a mixture of thymol and magnesium chloride is admixed and the mixture is incubated. The 30 to 40 mass parts of meat industry waste product treated in the above way and having dry material content of 10 to 40 mass %, 25 to 30 mass parts of residue material originating from biogas production, 10 to 20 mass parts of meat industry sewage sludge and 2 to 35 mass parts of pretreated chopped branches, -twigs vine-branches or -stalks of arboreous plants are mixed together and the mixture is then homogenized and optionally pre-milled and the mixture is composted in open or closed stacks, the compost - in a given case - is sieved after the thermophylic composting stage and the fine grained material is further composted.</p> |
