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

摘要

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 over estimates methane (CH_4) emissions; and the true CH_4 potential of waste depends on the level of segregation. Based on these findings, correction factors were developed to estimate CH_4 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.
