| Landfill gas from municipal solid waste is a climate liability and a renewable energy opportunity. In this study, methane (CH₄), carbon dioxide (CO₂), and non-methane organic compound (NMOC) emissions from Kashan landfill, located in a semi-arid region of Iran, were estimated and simulated, and its electricity potential was determined. LandGEM, a U.S. EPA first-order model, was applied with data from Kashan landfill, taking into account waste characteristics and decay rate constant (k = 0.0268 yr⁻¹), decay L (L₀ = 191 m³ CH₄ Mg⁻¹ waste). Peak methane emission occurred one year after closing (2036), with a rate of 9.85 Gg.yr⁻¹ (~14.8×10⁶ m³ yr⁻¹). Total landfill gas generated is 3.50×10⁴ Mg.yr⁻¹ at the end of filling (2035). Assuming a gas collection efficiency of 60% and electricity efficiency of 33%, total electricity produced peaks at ~27.1 GWh.yr⁻¹ (~27,091 MWh.yr⁻¹). These results show that LFG collection and use should be a priority for semi-arid region MSW landfills with large percentages of organic waste. | ||
