Methods of disposal of manure / litter. There is a large amount of biological waste as a source of organic nitrogen in humus-forming fertilizer. The solution to this situation is the use of a new technological process - blending manure / litter with slaughter waste, as well as subsequent autoclave treatment and drying of the mixture. Equipment for manure / litter drying can be installed on the territory of the livestock / poultry complex in a convenient location. Installation options will be

The set of equipment will be almost the same in all cases. As a fundamental decision on the use of new technology at the state level would be the following. Logistical, technological and territorial unification of two major tasks: disposal of solid waste with obtaining huge amounts of thermal energy and simultaneous disposal of manure / litter to produce humus- forming fertilizer. The economic efficiency of the proposed technology is determined by the cost of drying. The production of dried fertilizer is very energy intensive, since have to evaporate huge amounts of water.
