Abstract
This study assesses the landfill gas (LFG) production potential in Saveh City, Iran, utilizing the Landfill Gas Emissions Model (LandGEM) to estimate methane and other emissions based on the area’s waste characteristics, environmental factors, and projected waste volumes. Saveh’s landfill is expected to see increasing waste production, driven by urban population growth and economic expansion, with waste quantities rising from 150 tons daily in 2014 to over 175 tons by 2030. Given the semi-arid climate, methane generation is influenced by limited moisture, with waste moisture content typically between 20-30%. Methane and overall landfill gas emissions are projected to peak by the year 2035, aligning with the landfill’s maximum waste capacity. Environmental impacts associated with methane’s high global warming potential, along with health risks from non-methane organic compounds (NMOCs) such as benzene, underscore the need for emission control measures. Recommended strategies include methane capture for energy recovery, enhanced waste diversion programs to reduce organic input, leachate recirculation to optimize moisture, and NMOC treatment to mitigate air quality concerns. This analysis provides a framework for managing Saveh’s landfill emissions effectively, contributing to climate and health protection goals. Additionally, sensitivity analyses highlight how parameter adjustments, such as increased moisture or waste composition changes, could enhance methane recovery. The study demonstrates the importance of localized data in refining LFG models like LandGEM for accurate emission forecasting in specific environments.
