Investigation of Landfill Gas Output from Municipal Solid Waste at the Polygon

Abstract

The aim of the work is to study the output of landfill gas from the MSW landfill site, decommissioned 10 years ago, to determine the possibility of its energy use. The results of calcu-lations of the output of landfill gas from the site according to two methods, the results of instru-mental measurements of the bio gas composition, conducted during five months are presented. A series of measurements makes it possible to estimate the composition of the landfill gas being al-located in the absence of sludge: СH4 - 30 ... 32%; O2 - 0 ... 2%; CO2 - 40-60%; N2 - 5 ... 30%; H2S - 0 ... 30 mg / m3. Despite the lower methane content than in traditional bio gas, with regard to the energy potential, the landfill gas released at the experimental site allows it to be used pro-vided that the combustion process is necessary.
