This research addresses the use of methane (CH₄) for energy generation in a landfill located in Southern Mexico. To evaluate the feasibility of this renewable and sustainable energy project, a LandGEM model was used to estimate the CH₄-emissions, the environmental benefits and the economic profitability. Taken together, results showed an average CH₄-production of 2932 ft³/min, with a maximum CH₄-generation flowrate of 4072 ft³/min (115.3 m³). Energy generation resulted in 32.396 million KW h/year with a hot water/steam production of 63.990 million BTU/year. The installed capital costs of a 15-years project were estimated in $9,034,907 USD; economic parameters showed a financial profitability with a net present value of $6,304,060 and an internal rate of return of 25%. The environmental benefits reported a total collection and destruction of CH₄ at 9,824,469,979 ft³ (278,198,009.2 m³). The results obtained in this research can be used to conduct further studies to implement waste-to-energy technologies in Mexico and thus improve the sector of sustainable and renewable energy.

墨西哥南部垃圾填埋场甲烷排放产生能量的可行性

这项研究致力于将甲烷（CH ₄）用于墨西哥南部垃圾填埋场的能源生产。为了评估此可再生和可持续能源项目的可行性，使用LandGEM模型估算了CH _4的排放量，环境效益和经济效益。综上所述，结果显示平均CH _4产生量为2932 ft ³ / min，最大CH ₄产生流量为4072 ft ³ / min（115.3 m ³）。发电量为3239.6万千瓦时/年，热水/蒸汽的生产量为639.9万英热单位/年。一个为期15年的项目的安装资金成本估计为9,034,907美元；经济参数显示出财务获利能力，其净现值为6,304,060美元，内部收益率为25％。据报道，环境效益表明，CH _4的收集和销毁总量为9,824,469,979 ft ³（278,198,009.2 m ³）。这项研究中获得的结果可用于进行进一步的研究，以在墨西哥实施垃圾发电技术，从而改善可持续和可再生能源领域。
