Potential of Power Generation from Biogas. Part II: Municipal Solid Waste

The objective of this work is to estimate the amount of biogas that could be obtained\ud from the anaerobic decomposition of the organic fraction of the municipal solid waste\ud (MSW) disposed in a sanitary landfill, by capturing and taking advantage of it to\ud generate electricity which can be consumed by Ciénega Region of Chapala in the\ud state of Michoacán, México. To estimate the biogas captured, the Mexican Model of\ud Biogas version 2.0 was used; capturing MSW for 11 years with a project life of 21\ud years. For the analysis of power generation an average cost for schedule rate 5-A\ud from the CFE for public service was used. Four possible scenarios were evaluated:\ud optimal, intermediate optimal, intermediate pessimistic and pessimistic; varying\ud characteristics such as adequate handling site, fire presence, coverage, leachate,\ud among others. Each of the scenarios, economically justify the construction of an inter-municipal\ud landfill obtaining substantial long-term economic benefits. (26.5×106\ud USD, 22.8×106\ud , 17.9×106\ud and 11.7×106\ud respectively), while contributing to climate\ud change mitigation and prevention of diseases
