One major factor, contributing to the emission of greenhouse gas in the environment, is generation of hazardous gases in municipal landfills. Due to these potential negative impacts, it is obligatory to estimate the amount and type of landfill gasses to design and build a gas collecting system. Landfill gas emissions are governed by the type of waste, its biodegradability, its methane emission potential, the degree of separation, and other miscellaneous factors. LandGEM model was used to predict the amount of gases produced in the landfills of Trichy (Ariyamangalam) and Thanjavur (Srinivasapuram). According to the results, the largest amount of landfill gas emissions would be in 1993 for Trichy (Ariyamangalam) landfill and in 2027 for Thanjavur (Srinivasapuram) landfill. The total amount of produced gas, methane, and carbon dioxide would be 16.2E + 10, 8.2E + 10, and 16.2 + 10 cubic meters per year in 1993 for Trichy and 13E + 6, 5E + 6 and 13E + 6 cubic meters per year in 2027 for Thanjavur.
一个主要的因素，导致温室气体在环境中的排放，是在城市垃圾填埋场产生危险气体。由于这些潜在的负面影响，有必要估计垃圾填埋气体的数量和类型，以设计和建造气体收集系统。垃圾填埋气体排放受废物类型、生物降解性、甲烷排放潜力、分离程度和其他杂项因素的影响。LandGEM 模型用于预测 Trichy（Ariyamangalam）和 Thanjavur（Srinivasapuram）垃圾填埋场产生的气体量。根据结果，Trichy（Ariyamangalam）垃圾填埋场的垃圾填埋气体排放量最大的年份将是 1993 年，而 Thanjavur（Srinivasapuram）垃圾填埋场的最大排放量将是 2027 年。1993 年， Trichy 产生的总气量、甲烷和二氧化碳将分别为 16.2E+10、8.2E+10 和 16.2+10 立方米/年，而 2027 年， Thanjavur 产生的总气量、甲烷和二氧化碳将分别为 13E+6、5E+6 和 13E+6 立方米/年。
