ABSTRACT

Methane emission from open landfills in the cities is of great concern as it is responsible for global warming. Also, methane has a potential to be used as a fuel due to its calorific value. The quantification of the emission of methane from the landfill hence is important as it will help decision makers to understand the feasibility of deploying the landfill gas recovery system and the potential of the fuel and energy generation. The study was performed with an aim to find the methane emission values between 2020-2050 using default method (DM), first order decay method (FOD), modified triangular method (MTM) and LandGEM for open landfill at Moshi in Pimpri Chinchwad, Maharashtra, India. The estimated values of methane by DM, FOD, MTM and LandGEM methods are 557.6 Gg, 384.44 Gg, 397.28 Gg and 453.79 Gg respectively. The uncertainty assessment performed on these values demonstrated that comparatively higher values were obtained in DM due to a greater number of variable parameters as input. FOD method has less input parameters that vary and given values with lesser uncertainties. Values in MTM and LandGEM were found to have uncertainties too. The energy generation potential calculated using Yedla method was 24309.04 KJ.
