Methane is considered to be one of the main causes of global warming. Quantifying methane emissions from landfills is the subject of many studies, especially emphasizing the role of two parameters: methane generation potential capacity (L 0), methane generation rate (k). In this study, we propose a system of integrated environmental information and mathematical model named EnLandFill (EN vironmental information – model integrated system for air emission and dispersion estimation from LandFill) that allows calculation L 0 from database and experimentally to determine optimal k. To perform experimental calculations, meteorological data were extracted from the WRF model and verified with real measurements. The novelty of this study lies in the inferred database system, the math model bank, especially the dispersion model, taking note account the complex topography, meteorological factors that change by the hour. EnLandFill was applied to Phuoc Hiep Landfill (PHLF) in Ho Chi Minh City as a case study, the results have identified the amount of methane released that is equal to 44,094,697.88 m3/year in 2019, but EnLandFill is designed to be general, applicable to other landfill entities. Unlabelled Image • Proposed a system of integrated environmental information and mathematical model named EnLandFill that allows calculate the potential methane generation capacity and experimentally to determine optimal methane generation rate. • The proposed system allows the assessment of the scope and extent of impacts caused by the dispersion of toxic substances from landfills. • Using the proposed system it is allowed calculate the amount of methane emitted from Phuoc Hiep landfill (PHLF) - the largest waste treatment complexes in Hochiminh city for 2019 is 44,094,697.88 m3/year.
