Open dumping of municipal solid waste (MSW) is a common practice in many parts of the world. Since such dumpsites are open to atmosphere, greenhouse gases (GHG) released to the atmosphere causing global warming. Hence it is necessary to quantify landfill gas (LFG) emissions from MSW landfills. In the present study, physical composition of MSW samples collected from a nearby landfill in Bengaluru, Karnataka, India has been studied. Also, grain size analysis has been conducted through dry sieve method. Finally, total LFG emission including methane, carbon dioxide has been predicted for the post-closure period using LandGEM model considering five years as active period of landfill. Physical composition analysis of MSW samples revealed that organic content (53.63%) and plastics (20.49%) as major constituents along with metal, fabrics, papers and glass. Average initial moisture content of the MSW sample was found to be 46.148%. Cu and Cc values were found to be 22 and 1.13, respectively. Particle size distribution curve obtained from the sieve analysis has been presented. Input data for the modelling has been used from field visits, available literatures as well as default values available in LandGEM model itself. Total emissions for LFG containing, methane, carbon dioxide and NMOCs were found to be 2373 Mm3, 1186 Mm3, 1186 Mm3 and 9.5 Mm3, respectively.
