The article analyzes the existing problems associated with the degassing of landfill and the use of landfill gas as an energy resource. Issues related to the composition of the landfill gas are considered. The main reasons for the high nitrogen content in landfill gas are shown. The main measures are highlighted that make it possible to increase the economic attractiveness of the use of landfill gas. A fundamentally new technology of combined fermentation has been proposed, combining the fundamentals of the technologies of “dry” and “wet” fermentation of various substrates. The paper presents the results of using the technology of combined fermentation to increase the efficiency of the active decontamination system of the MSW landfill of WSC Vodino LLC. A significant improvement in the composition of landfill gas was noted, first of all, an increase in the volume fraction of methane and an increase in the average daily volume of recoverable landfill gas by 22%. As a result, the daily production of heat and electricity at the site during the experiment increased by 79.6%. As a side effect in the experiment, a decrease in the height of the horizon of the landfill body was noted by 12.5% and, as a consequence, an increase in the useful capacity of the landfill.

Now in metallurgical production energy resources demand is almost completely satisfied by gaseous fuel. Biogas obtained during organic waste processing is considered as an alternative and cheaper type of fuel. The experience of biogas application has shown that in most modern burners decrease of efficiency and limitation of the range of load regulation is observed. To apply biogas in an industrial environment, it is necessary to develop burners and the methods of its combustion, which provide a high combustion efficiency, as well as a higher energy conversion efficiency. The authors have used the results of gas analysis of biogas obtained in the process of anaerobic decomposition process of organic waste in the reactors of a bioenergy plant. Methods of mathematical statistics with the use of regression analysis of experimental data were used to assess the indicators of the energy efficiency of the gas burner. The possibility of using biogas and landfill gas in the process of roasting, blast-furnace smelting, production of rolled products and steel, as well as heat treatment of metal has been experimentally proven. The properties and composition of biogas at the outlet of the methanogenesis reactor of the bioenergy plant “EcoVoltAgro” are described. A new design of a gas burner is proposed. In this model the efficiency of mixture formation and the completeness of combustion of the flow of a methane-containing gas mixture are significantly increased (up to 32 %) due to the effect of rotation of the perforated pipelines of the gas inlet pipe. On the basis of the results of the full-scale experiment, the optimal values of the gas-air mixture supply rate, the temperature of the supplied air, the volume fraction of methane were determined in order to obtain the largest width of the zone of deviations of the permissible concentrations of carbon dioxide. The use of the designed gas burner provides energy-efficient combustion of biogas in metallurgical furnaces, kilns, and dryers, as well as in any steam and hot water boilers.
