COST BENEFIT ANALYSIS OF MUNICIPAL SOLID WASTE DISPOSAL: CASE STUDY IN KIEU KY AND NAM SON LANDFILLS IN HA NOI

Abstract

In recent years, along with the rapid development of the economy and the rapid urbanization process, municipal solid waste (MSW) treatment has become anurgent issue that needs to be addressed, especially in the big cities. By analyzing costs-benefit of Kieu Ky and Nam Son landfills, this study shows that in the near future MSW disposal will remain to be one of themost effective treatment measures due tolow cost of construction and operation and simple technology without reaquiring highly skilled labor. Results show that small scale landfills like Kieu Ky (handling lessthan 100,000 tons of MSW per year) is more cost – effec-tive and environmentally friendly (in term of greenhouse emission reduction) than large scale landfills like Nam Son (handling lessthan 200,000 tons of MSW per year). Thus, small-scale MSW disposal projects should be prioritized rather than large scale MSW disposal projects in order to limit the impacts on the environment. In addition, it is also required that MSW disposal projects provide adequate compensation to nearby residents to mitigate the damage to their health and production.
