Abstract: Municipal solid waste (MSW) management is one of the important global issues in this era. To minimize this problem, several techniques have been employed for escalating MSW. However, the emissions of the MSW management sector impact the environment and human health. This study mainly focuses on the MSW in the municipal area of the Yangon city, Myanmar on the characteristic of background information (center of economic zone, densely populated, rapid MSW generation and its composition, absence of collection system, unorganized recyclable materials, and current waste practicing). This research approaches the life cycle assessment (LCA) and cost-benefit analysis (CBA) method. A cradle to grave system boundary deals with a functional unit of 1 ton of MSW. The purpose of this study is to estimate the potential environmental impacts and the economic feasibility of MSW projects to propose sustainable MSW management system for Yangon city. The municipal area disposes approximately 93% of its generation to open dumping sites. This study analyzes the six environmental impacts using LCA and estimates the economic feasibilities of the project using CBA to support the decision-maker to choose the sustainable management system. The LCA results show that a BAU scenario is the highest environmental impact and scenario F would reduce the impacts than the other scenarios. The CBA results show that BAU is the lowest economically feasible option and scenario E is, on the other hand, the most economically feasible. By means of the LCA and CBA method, it can provide the important suggestion to pinpoint the upgrade MSW management in the municipal area to contribute to the National Solid Waste Management Strategy and Master plan of Myanmar
