Abstract
The problem of the impact of MSW landfills on the atmosphere is considered. Biogas collection systems were investigated. Modern methods of biogas utilization are analyzed. The technological scheme of processing of gas generated at MSW landfills for the production of gas hydrate from the main macro-components is presented.
Highlights
Landfill as a complex engineering structure, the main element of which is a waste storage array, on the one hand, is designed to provide protection from pollution of the atmosphere, soil, surface and ground water
In Russia, the disposal of waste in landfills and landfills remains the main method of waste management
According to the Russian Environmental Operator [2] on the territory of the country, in 2019, 65 million tons of solid municipal waste were generated, 18.2 million tons of MSW were sent for processing (28% of the total volume); during the same period, 4.55 million tons were sent for reuse (6% of the total volume)
Summary
Landfill as a complex engineering structure, the main element of which is a waste storage array, on the one hand, is designed to provide protection from pollution of the atmosphere, soil, surface and ground water. The waste disposal array functions as a bioreactor, in which biological, chemical and physical processes occur, inevitably accompanied by emissions of pollutants. According to the Russian Environmental Operator (hereinafter referred to as REO) [2] on the territory of the country, in 2019, 65 million tons of solid municipal waste were generated, 18.2 million tons of MSW were sent for processing (28% of the total volume); during the same period, 4.55 million tons were sent for reuse (6% of the total volume). After the operation of the landfill map is completed, in order to reduce the negative impact on the environment, passive and active degassing systems are installed, which allow collecting the biogas generated during the decomposition of waste from the landfill body
