METHANE EMISSIONS FROM OPEN DUMPSITES IN INDIA - Estimation and mitigation
18 September 2023
The FOD model used in the BUR is based on the following equation: Mt = Mo * e -kt where: • Mt is the amount of methane generated at time t • Mo is the initial amount of methane generated • k is the decay rate constant The decay rate constant is a function of the temperature and moisture content of the landfill or dumpsite. [...] However, the temperature and moisture content of landfills can vary depending on the location of the landfill, the depth of the landfill, and the type of waste that is landfilled. [...] The composition of waste in India can vary significantly from the composition of waste in the United States, and the climate in India can also be different from the climate in the United States. [...] Secondly, the accuracy of the data used can vary depending on the source of the data and the methods used to collect the data (see Chapter 4 for detailed discussion on accuracy of data on waste disposed of in dumpsites). [...] Where QCH4 Emission is the amount of methane emissions (Gg/year), MSWt and MSWf are respectively the waste mass (Gg MSW) and the fraction of municipal solid waste landfilled for the considered year; DOC and DOCf are respectively the Degradable Organic Carbon (Gg/Gg MSW) and the fraction of DOC dissimilated; F is the fraction of CH4 in the landfill gas (set equal to 0.5); MCF is the methane correct.
