Environmental Resource Saving Biogas Production

Abstract

The largest producer of poultry meat in the Far East of Russia, the poultry factory “Mikhailovsky Broiler”, in addition to food products, produces waste in large amounts in the form of bird manure. The manure is wasted if it is not recycled but simply stored. By trying to solve the problem of recycling and processing of bird manure, the enterprise has found a way that allows not only to neutralize a huge amount of waste of the fourth class, but also to produce a significant amount of methane gas. When methane is burned, thermal energy is produced that can be used year-round in the technological processes of the enterprise. The second, and no less valuable product of manure processing in the proposed technology is biohumus, which is in demand on local and international markets. In the course of test experiments of the technology in fermenting bird manure, the limitations inherent in the processing of pure poultry manure, other than ruminants' manure, have been clarified. For their elimination the processing technology has been significantly refined by the experts of the research organization, and has been patented. The practical justification for the anaerobic fermentation of the poultry manure was confirmed in the experimental reactor fabricated at the plant in 2011. The proposed manure processing solves the environmental problem, opens up additional sources of resource saving and additional profit for the enterprise. The selling of biohumus to agricultural enterprises in the region makes possible to significantly increase the yield of agricultural crops.
