Abstract
The article discusses landfills for disposal of municipal solid waste, landfill biogas as an energy resource and its negative properties. We consider the problems of growth of volumes of solid municipal waste in the world and use of landfill gas for energy purposes. Moreover, the article analyzes the ratio of the volume fractions of the major macrocomponents of landfill biogas and the reasons for the high nitrogen content in the composition of the landfill gas. It shows the results of research in the field of cogeneration and trigeneration energy from gas mixtures and formulates the principles of creation of better treatment and landfill gas combustion systems. We develop an effective and lowcost method for increasing the methane component in reducing the nitrogen content in the landfill gas and consider the application of biological products on the basis of methane effluent for processing substrates in the body of the landfill to increase the proportion of methane and environmental safety. The article assesses the expected effect, the positive results of the implementation of the proposed method and proposes set of measures to improve the efficiency of degassing municipal solid waste (MSW) landfill. The demand of this technology for the exploited and newly commissioned MSW landfills inRussiaand abroad is approved.
