TECHNOLOGICAL CHARACTERISTICS AND POTENTIAL OF LANDFILL BIOGAS FOR ELECTRICITY GENERATION

Climate change, which is observed on our planet at an unprecedented rate over the past decades or even millennia, is one of the most influential risks that determine the global development of mankind. Changes in the climate system pose serious threats and challenges to the sustainable development of society, caused by increased risks to human health and life, natural ecosystems, economic sectors and require detailed research and development of adaptation measures. Waste is one of the biggest problems of mankind today. Waste accompanies a person at every stage of his activity and requires a close approach to the issue of their disposal – burial at special landfills. This solution is not optimal, because it requires the annual alienation of land for the expansion of landfills and construction, and investments in these landfills, which must meet all technical and hygienic requirements. However, even landfills that meet all the established requirements cannot guarantee environmental safety. The landfill for waste disposal is a kind of biogas generator (landfill biogas), which is formed as a result of the decomposition of the organic waste fraction. This work is devoted to the analysis of modern designs for the collection and removal of landfill biogas, mathematical models for assessing the level of methane formation of solid waste landfills, the potential and prospects for the development of biogas power plants to reduce greenhouse gas emissions. A rational solution to these problems is the use of renewable energy sources, including biogas, the gas emitted by production and consumption waste in landfills of such waste. A prospective analysis of the volume of biogas was carried out on the example of a landfill for municipal solid waste in the city of Kamianets-Podilskyi, Khmelnytsky region (Ukraine).
