Greenhouse gas emissions from municipal solid waste disposal sites – a case study in Hoi An city. Currently, climate change shows an increasingly high intensity and anthropogenic greenhouse gas emissions are shown as the main drive force of rapid 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. | No 6(31) – 2016, Dec. 2016 Scientific Journal Of Thu Dau Mot University GREENHOUSE GAS EMISSIONS FROM MUNICIPAL SOLID WASTE DISPOSAL SITES – A CASE STUDY IN HOI AN CITY Pham Phu Song Toan, Tran Minh Thao, Tran Thi Ngoc Linh Danang College of Technology – The University of Danang ABSTRACT Currently, climate change shows an increasingly high intensity and anthropogenic greenhouse gas emissions are shown as the main drive force of rapid 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. The flow of solid waste in disposal sites was analyzed and the sources of greenhouse gas emissions were identified by the Life Cycle Assessment (LCA) and Nordtest methods. In addition, IPCC-2006 was a main tool for calculating, estimating and forecasting amount of greenhouse gas. The results of this study shown 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 , and of total GHG, respectively. Additionally, 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 ( - 6,004 tons of CO2-eq), N2O ( - 2,357 tons of CO2-eq) and CO2 ( - 505 tons).

INTRODUCTION In recent years, anthropogenically induced climate change becomes an alarming problem of the whole world. . Viet et al., shown that from 2004 to 2014 the shoreline of Cua Dai Beach in Hoi An City (HAC) had been eroded, slid and engrained 500 m along the coastline. This erosion pulled down many hotels, buildings and threatened the lives of fishermen [1]. The rise of greenhouse gases .
