Development of correction factors for landfill gas emission model suiting Indian condition to predict methane emission from landfills

Methane emission from landfill gas emission (LandGEM) model was validated through the results of laboratory scale biochemical methane potential assay. Results showed that LandGEM model overestimates methane (CH₄) emissions, and the true CH₄ potential of waste depends on the level of segregation. Based on these findings, correction factors were developed to estimate CH₄ emission using LandGEM model especially where the level of segregation is negligible or does not exist. The correction factors obtained from the study were 0.94, 0.13 and 0.74 for food waste, mixed un-segregated municipal solid waste (MSW) and vegetable wastes, respectively.
