Research on landfill gases (LFGs) collection mainly consisting of CH4 and CO2 gases, is not only a solution to decrease environmental risks but also to utilize and generate an alternative clean power source ​​of coal. Many typical landfill cases in Vietnam, which install a recovery system and remove captured CH4 by the flaring methods, are able to contribute to reducing significantly greenhouse gas (GHG) emissions with roughly 0.25 tCO2–eq/tons being equivalent to 7.8 million tons of CO2–eq/year. Furthermore, a wide range of LFG recovery projects financed by the World Bank was conducted on 27 landfills in 19 cities of Vietnam, which generated a potential of GHG emission reduction up to 1,116,068 tCO2–eq/year. However, quantification of biogas emissions for each landfill as a basis in order to design and construct a suitable recovery system always has to face many challenges. The purpose of this study to propose an integrated system including a database combined with mathematical models in a Web–based packaged software named EnLandFill to be able to accurately quantify the emission load of GHGs and estimate electricity production generating from recovered LFGs. On a case study of Tien Giang province, total maximum cumulative emissions of LFGs, CH4, and CO2, which is around 279 million m3, 145 million m3, and 134 million m3 respectively, have been forecasted in scenario 1 for the period of 2021–2030. Additionally, the annual electricity generation potential is highest in scenario 2, estimating a total value of over 800 million kWh.
