Mathematical Model of the Process of Degassing Landfill for Municipal Solid Waste

This is the authors' abstract. We don't add key points for this paper.

A mathematical model of methane filtration to a well in the body of a municipal solid waste (MSW) landfill during degassing has been developed. The identity of the obtained calculation results using the empirical model with the results of field measurements at the landfills reclaimed by the authors in the Moscow region was noted. It has been confirmed that the mathematical model tested in practice and the results of its numerical study make it possible to predict the process of landfill degassing over time at the design stage, as well as during operation and after its reclamation. It is concluded that forecasts of methane emissions from the body of the landfill into the atmosphere serve as the basis for the development of technologies and equipment to ensure environmental sanitary and fire safety of the territory in the area where the MSW landfill is located, as well as urban planning plans for the development of settlements.
