Abstract
The urban environment is increasingly becoming a unique challenge for climate change. Landfills represent significant sources of greenhouse gasses, primarily in the form of carbon dioxide (CO2) and methane (CH4) emissions, which are both potent greenhouse gases that contribute to climate change. To reduce the gaseous emission impacts, it is crucial to select landfill sites carefully, consistent with urban sustainability goals. In the present work, an air quality dispersion modeling was conducted to evaluate the impact of the methane (CH4) and carbon dioxide (CO2) dispersion emitted from major landfill sites in Kuwait during different seasons. The atmospheric dispersion of the CH4 and CO2 was modeled. AERMOD-ISC dispersion model was used to estimate hourly concentrations of the CH4, and CO2. The predicted of CH4 and CO2 are presented in the form of concentration contours to determine the dispersion of CH4 and CO2 emissions and to assess the impact on ambient air quality over residential area. The results obtained indicate that high concentration for CH4 and CO2 were found to occur close to landfill emission. Residential area during winter and fall seasons exposed to CH4 and CO2 emissions. The concentration of CH4 and CO2 emissions increased during spring season. The dispersion of CH4 and CO2 emissions during winter and spring was found to be longer than that during summer and fall seasons. Utilizing the air quality models helps landfill owners and decision makers to reduce methane and carbon dioxide emissions on ambient air quality.
