TÓM TẮT
Nowadays, climate change is getting more complicated with high intensity and greenhouse gas emissions are believed as the main cause of climate change. In 2015, Hoi An City emitted 8,855 tons of CO2-eq from municipal solid waste disposal sites, which treated 25,000 tons of solid waste from domestic and tourist activities. Base on the Life Cycle Assessment (LCA) method and Nordtest methods, the solid waste flow in disposal sites was analyzed and the sources of greenhouse gas emissions were identified. In addition, IPCC-2006 was a main tool for calculating, estimating and forecasting amount of greenhouse gas. The results of this study showed that some activities in Cam Ha Composting Facility emitted 5,522 tons of CO2-eq, in which activities of using electricity, combusting diesel fuel and composting process were 1.6%, 7.8% and 90.6% of total GHG, respectively. Besides, 3,344 tons of CO2-eq was emitted from decomposited of Landfill site. Furthermore, this study was analyzed specifically the composition of GHG whereby three main components were calculated such as CH4 (67.7% - 6,004 tons of CO2-eq), N2O (26.6% - 2,357 tons of CO2-eq) and CO2 (5.7% - 505 tons).
