Rapid increase in volume and types of solid waste generation due to economic growth, urbanization and industrialization has become a problem in developing countries including Thailand. Urban cities in Thailand such as Nakhon Ratchasima City Municipality (NRCM) have put sustainable waste management among their top priorities. One way to solve this problem is to convert waste to energy. Municipal Solid Waste (MSW), as source of fuel, decreases need for landfill volume, thus freeing sites for other more useful purposes; it also contributes to a decrease in fuel demand, thereby protecting environment. Despite the fact that integrated waste management has been used widely in the country, there are rooms for improvement of the system being used to increase an effectiveness of the system. At the NRCM, mixed MSW are being converted to renewable energy such as Refuse Derived Fuel (RDF) and biogas production. However, large amount of MSW are still being disposed in the landfill. This study is focusing on an assessment of waste management process at NRCM to determine its efficiency, environmental impacts and impact mitigation measures in all the stages of waste management system. Data compiled for analysis include waste generation and separation at source, characterization of waste feedstock, and material flow through integrated system being employed at the NRCM. Problems encountered in each step were identified. In addition, this study proposes improvement measures for the waste management services to maximize resource recovery and resource utilization.
