Abstract: The main objectives of this study consists of the following: 1) investigating the determinants of MSW generation and collection cost, 2) examining the role of social capital to promote community participation in household waste recycling, and 3) performing economic evaluation for the application of social capital to MSW management. To investigate the determinants of MSW generation and collection cost, the data was collected from questionnaires that were posted to 570 municipality’s executives/chiefs across the country. In the analysis of the relationship between social capital and community participation on recycling activities, the data was collected from households with a total of 500 observations in the Bang Kruai Town municipality: Nonthaburi was selected as the case study. Then, the economic evaluation of the application of social capital and community participation to MSW management was performed by using the cost benefit analysis (CBA). The results of this study showed that the population growth and urbanization were the key factors in the MSW generation, which results in a rapid growth of the MSW collection cost. Considering the role of social capital in MSW management, social capital is associated with the collaboration of the community in household waste recycling. The households’ participation in recycling activities has significantly reduced household wastes by about 32 percent. The estimated economic benefit from the application of social capital to build participation in MSWM of the municipality in three scenarios includes a social capital that causes the network to access the household waste recycling activities: this is for one-fourth, one-third and a half of all community in the municipality. In the case of social capital causing the network to participate in the recycling of waste, one-fourth of the entire community in the municipality enabled the cost of collection to come down from the recycling of waste compared to the ratio of savings to investment (SIR) was between 1.945 to 3.037 times and the adjusted internal rate of return was between 55.2% to 105.2%. Meanwhile, the case of one-third of the entire community in the municipality with the ratio of savings to investment (SIR) was between 2.309 to 2.829 times and the adjusted internal rate of return was between 75.7% and 110.3%. Finally, the case of a half of the entire community in the municipality with the cost of collection down from the recycling of waste compared to the ratio of savings to investment (SIR) was between 2.881 and 3.037 times and the adjusted internal rate of return was between 110.8% and 120.6%
