Abstract: Methane gas is one of the important greenhouse gases, which has the highest effect on global warming. One of the main methane emissions sources is landfills. Predicting the amount of methane gas collection from the closed landfills can justify the merits of installing required facilities for this purpose. Potential methane gas production from Kerman, Iran wastes was measured by using LandGEM software. The results showed that methane gas in this landfill in 2015, 2021, 2027 and 2033 will produce roughly 72, 2,540, 3,914 and 5,015 m³ h⁻¹, respectively. Therefore, the amount of methane gas production in the Kerman landfill with the capacity waste production between 355,200 to 622,845 tons annually will be 72 to 5015 m³ h⁻¹. The results of this study could be used for the design and estimation of the methane gas systems and as a plan for the control management of methane emissions in Iran's landfills.
