COMPARISON OF MODELS FOR LANDFILL BIOGAS EMISSION AND POSSIBLE APPLICATION OF METHANOTROPHIC MICROORGANISMS

Abstract:

Landfills are one of the largest anthropogenic sources of methane gas, which is highly polluting if it is not used or managed in any way. In this case study. the amount of biogas produced in the "Sanitary Landfill of the City of Macas" was estimated. Estimations were made using three landfill gas generation models: Ecuadorian. EPA, and IPCC. Average values of biogas generation, calculated with the models mentioned above, were 156.24 m(3)/h, 76.78 m(3)/h, and 102.86 m(3)/h, respectively. The best projection results were obtained with the IPCC model, since it takes into account, in a more specific way, the climatic conditions of the zones. In addition, a proposal was made for the reduction of methane gas emissions in the landfill by applying methanotrophic microorganisms into its soil; estimating a 57,17% reduction, In conclusion, both the EPA and the IPCC models project an exponential growth of biogas …
