Power generation with biogas from municipal solid waste: Prediction of gas generation with in situ parameters

摘要: Abstract Estimations of biogas emissions in final disposal sites have been studied by several researchers, primarily for their potential as a renewable source energy and greenhouse gas mitigation. Different models developed to predict the generation biogas; first-order model is widely used. Most these are based on two parameters, methane rate (k) (L0). These parameters cannot be generalized estimation any site, must modified according situ characteristics. The objectives this research (a) modify constants k L0 with data, (b) estimate sanitary landfill Mexican city using constants. following data were used modifying biogas: waste characterization studies, extraction tests, (c) observations characteristics operation, (d) interviews managers landfill, (e) Intergovernmental Panel Climate Change (IPCC) model. Biogas was performed version 2.0 Mexico Landfill Gas Model proposed Stearns, Conrad Schmidt Consulting Engineers, Inc. (SCS Engineers). results show that approximately 70% generated organic, which influences value calculating L0. With characteristics, values k=0.0482 yr−1 L0=94,457 m3/t obtained. It projected electric power could reach maximum capacity 2.4 MW 2019. This increase installed Ensenada 4.36% supply 66% required lighting, amounts savings US$2.62 million an environmental benefit 1.17 Mt CO2e from 2009 2025.
