Abstract

Highlights: A web – based platform for methane emission modelling from landfills is proposed. Model integration technology with databases and GIS are described. The inverse algorithm is built to determine the emission source capacity. To quantify CH4 emissions for SKER about 158, 977.77 tons in the period 2019–2030. The results of CH4 pollution dispersion simulation is performed. Abstract: This study developed a platform using a modelling and web technology approach to estimate methane emissions from landfills to assess methane emissions across the region. The web technology-based software EnLandFill, which was developed, allows users to log in, interact with landfill databases, and document and extract information regarding landfill emissions. Models that integrate web technology with databases and geographic information systems (GIS) are described. One of the achievements of this study was the development of an inverse algorithm to determine the waste source capacity according to a dispersion model, accounting for complex terrain and meteorological time-series data extracted from the Weather Research and Forecasting (WRF) model. EnLandFill software was applied to quantify CH4 emissions for key developing regions, predicting approximately 158, 977 tonnes, equivalent to 167, 786, 878 m 3 of CH4 for the period of 2019 – 2030. The software also allows the evaluation of the scope and level of impacts of landfill emissions under given meteorological conditions.
