Huge quantity of methane gas is emitted from no-regulated municipal solid waste landfill to the atmosphere. Many researches have been done with the purpose to estimate the quantity of generated methane gas, capture, utilize and to use of this energy source to produce electricity or heat, since then many models have been developed to calculate landfill gas generation. In this paper the improved version, LandGem 3.02, is presented to estimate emission rate for the total landfill gas, methane, carbon dioxide from Tanjulangsat, municipal solid waste landfill, Malaysia. This landfill start operation at 2002 and it is expected to have lifespan of 20 years but due to industrialization and urbanization is predicted the landfill will reach its maximum capacity at the end of 2012. LandGem determines the mass of methane generated by using the methane generation capacity, the mass of deposited waste, deposited methane generation potential and methane generation rate. Obtained result shows the rate of methane generation from solid waste by 4.436E+02 (Mg/year) in 2003, first year after waste acceptance by landfill while the maximum methane generation rate occurred during the years 2012-2015 where indicate as the peck of generation by approximately 4.17 E+03 (Mg/year). On the basis of the theoretical information calculated by LandGem, it can be assumed that, volume of generated methane from solid waste within years of residence time in a landfill is sufficient enough to be considered for install the methane capturing facilities.
