This study examined the emission of greenhouse gases from municipal solid waste disposal centers in different regions of Iran based on different scenarios. Assuming landfill site opening in 2012 and considering the 20-year plan period for its usage, the amount of wastes entering the landfill site was calculated for 2012–2032. For calculating the production of methane (CH₄) and other gases during different years of the project, Land-GEM and IPCC model were used. We defined 9 scenarios for these two models based on the growth rate of population and waste generation. The results revealed that the lowest amount of gas emission in nine scenarios by Land- GEM model was related to non-methane organic compounds (NMOCs). According to the results obtained, the total emissions of greenhouse gases from sanitary landfills for Iran in 2032 were 3,844,000 Mg/year, the largest and lowest amounts of gas emission were related to Tehran region, 860,400 Mg/year, and the South Coast area of the country,138,200 Mg/year, respectively. The major section of the gas production in both landfills was related to greenhouse gas and carbon dioxide emissions. The difference in gas production in the studied regions was due to differences in the percentage of moisture and organic compounds.

本研究根据不同情景考察了伊朗不同地区城市固体废物处理中心的温室气体排放情况。假设垃圾填埋场于2012年启用，并考虑其20年计划使用期，计算出2012-2032年进入垃圾填埋场的废物量。为了计算项目不同年份的甲烷（CH ₄ ）和其他气体的产量，使用了Land-GEM和IPCC模型。我们根据人口增长率和废物产生量为这两个模型定义了 9 个场景。结果表明，Land-GEM 模型中九种情景中气体排放量最低的气体排放量与非甲烷有机化合物（NMOCs）有关。根据所得结果，2032年伊朗卫生填埋场温室气体排放总量为3,844,000毫克/年，气体排放量最大和最低的是德黑兰地区，860,400毫克/年，以及伊朗南部海岸地区。该国分别为 138,200 毫克/年。两个垃圾填埋场产生的气体主要与温室气体和二氧化碳排放有关。研究地区天然气产量的差异是由于水分和有机化合物的百分比差异造成的。
