摘要
Due to booming economy, growing population and rapid urbanization, solid waste generation in the cities of developing countries has significantly increased. Yangon is the largest and most densely populated city, with over five million residents in Myanmar. Open dumping is the major waste disposal method and recycling sector remains at an early development stage. With increasing waste generation, current waste management activities in Yangon have significant environmental impacts. Therefore, the study developed two linear models to predict annual solid waste generation, regarding per capita waste generation, population growth scenarios, literacy rates and gross domestic products. The Intergovernmental Panel on Climate Change and Institute for Global Environmental Strategies calculation methods were used for greenhouse gas (GHG) emission prediction from recycling, waste transportation and final disposal sites (FDSs). As a result, the total annual waste generation and GHG emission in 2015 may double over the next decade. Two major FDSs, Htawe Chaung and Hteinpin, may contribute waste disposal of 272-797 kilotons per year and emit 177-518 Gg of CO2-eq per year by 2025. The assessment of annual solid waste generation and GHG emission potential may offer advantages in assisting development of waste management plans in Yangon.
