Bangkok, the capital and the fastest growing city in Thailand, has continuously witnessed accumulating MSWM problems. As other urban cities in developing countries, the amount of generated MSW in Bangkok mainly depends on population, economic growth, and the efficiency of reuse and recycling systems. Both economic development and the higher number of population have dramatically increased MSW generation amount in Thailand, from 48 million tons in 1982 to 65 million tons in 2012. As of December 2012, the population in Bangkok was 5,673,560, or about 9% of the total population in Thailand, and there were more than 300,000 tons of MSW generated monthly in Bangkok
