Track: Waste Management

Abstract

Energy recovery by appropriate management of solid waste from municipal can be the solution to sustainable waste management as well as providing energy security in Bangladesh. However, the choice of appropriate waste to energy technology is a complex and challenging issue as a widespread variety of environmental, economic and social controlling criteria need to be identified and investigated. In this paper an Analytic Hierarchical Process is used to find the most preferable waste to energy technology by evaluating environmental, economic and technical criteria. The technologies considered were anaerobic digestion, gas recovery from landfill and incineration. Conducting a qualitative and quantitative assessment a preference ranking is produced which concluded that anaerobic digestion is the preferred technology for Bangladesh based on cost, benefit and environmental risk. We believe this study will provide a guideline for waste to energy decision makers in Bangladesh alongside with other similar developing countries.
