Abstract
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 different, depending on the type of manure / litter, the presence / absence of slaughter production, the type of animals or birds, but only slightly. 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.
Highlights
The development of animal husbandry and poultry farming in the Russian Federation has created serious problems of waste disposal [1]
A valuable resource is obtained in the form of tens of thousands of tons of technical distillate, which can be used in agricultural production. The presence of such a huge amount of heat energy is the basis for the implementation of a new technology for drying manure/manure, using a contact method of heat transfer from the heated wall directly to the mass of manure
An additional effect is the absence of costs for the disposal of growing and slaughter waste as a separate technological chain with the necessary equipment, personnel, product quality, etc
Summary
The development of animal husbandry and poultry farming in the Russian Federation has created serious problems of waste disposal [1]. Do not solve problems for a number of technical, technological, logistical reasons, but, most importantly, they do not give a significant economic effect after disposal manure / droppings in any way [2,3,4,5]. There is a typical vicious situation of "work for the sake of work" has developed, encouraged and initiated by law The solution to this problem on a national scale and for an individual manufacturer exists and is a comprehensive solution [7,8,9] in conjunction with the utilization of municipal solid waste as a source of thermal technological energy (MSW has a significant scale, there will be enough for everyone)
