With the growth of municipal solid waste (MSW) around the world, there is a significant increase in greenhouse gas emissions, mainly methane and carbon dioxide, emitted at landfills. Methane has a global warming potential that is more than 25 times that of CO2, making it one of the most dangerous constituents for the climate. In the context of modern environmental and climatic challenges, it is extremely important to develop effective methods to reduce methane emissions from MSW landfills and optimize the processes of its processing into biogas. Biogas plants at landfills offer the possibility of methane utilization while simultaneously obtaining a valuable energy resource that can replace traditional fossil energy sources and contribute to the energy security of the regions.

Purpose – to develop a mathematical model that will take into account the time dynamics of the biogas synthesis process at MSW landfills and will allow predicting the volume and composition of biogas (methane, carbon dioxide and other components) under various environmental conditions.

A mathematical model for the synthesis of biogas at solid municipal waste (MSW) landfills has been developed, taking into account the time dynamics of the process. key factors affecting biogas production, such as ambient temperature, landfill internal temperature, humidity and organic waste decomposition rate, were analyzed.

The model allows you to predict the volume and composition of biogas, in particular, the concentration of methane and carbon dioxide, under various external conditions. The use of the developed model will reduce greenhouse gas emissions from landfills, increase the efficiency of waste processing and improve the environmental situation.
