DETERMINATION OF THE POTENTIAL FOR BIOGAS GENERATION FROM MUNICIPAL SOLID WASTE THROUGHOUT THE LIFE CYCLE ON THE EXAMPLE OF THE TORBEEVO LANDFILL

At the global level, landfills are the third source of greenhouse gases in terms of the total impact on the atmosphere, generating 11% of the global amount of methane emissions [4]. The potential impact of methane (CH4) on global climate change, according to various estimates, is from 20 times to 84 times [2] greater than the impact of carbon dioxide (CO2), so the capture and further utilization of CH4 is one of the important ways to prevent global warming [5]. The most effective method is degassing systems based on equipping landfills with biogas extraction complexes, drying it and using it, for example, to generate electricity. To create this system, it is necessary to understand the volume of generated biogas. For these purposes, there are mathematical methods for estimating the volume of generated gas. In the article, for comparison, two methods will be considered and calculations based on data from the Torbeevo MSW landfill will be carried out.
