Application of Cost-Benefit Analysis and Data Envelopment Analysis to Evaluate the Municipal Solid Waste Management Projects in Metro Manila

摘要

Based on consultations with a municipal solid waste management (MSW) expert group, this study elucidates how governmental officials can solve the problems surrounding municipal solid waste management in Metropolitan-Manila. A crucial related issue is how the expert group can better evaluate MSW solutions and select favorable ones better evaluate and select a favorable MSW solution using a series of criteria. MSW solution selection is a multi-criteria decision-making problem, which requires considering numerous complex criteria. The study applies cost-benefit analysis (CBA) and data envelopment analysis (DEA) to determine the benefits and cost/input and output technical efficiency of alternative projects, which affords financial data information that evaluators can use for economic decision-making regarding MSW projects. Results of this study suggest that the thermal process technology is less efficient than resource recovery using DEA. Nevertheless, the net benefits of resource recovery exceed those of the thermal process technology by CBA.
