Harnessing waste-to-energy potential in developing countries: a case study of rural Ghana.

Abstract

This study examines factors that define a suitable waste-to-energy (WTE) technology and identifies an appropriate WTE technology that can be deployed to improve waste management in rural areas. Observations, questionnaires and interviews were used to collect data from waste management experts at Atwima Kwanwoma District and the residents in Kwanwoma township in Ghana. This study established that the following major factors define a suitable WTE technology for the Kwanwoma township: the initial capital or set-up costs, feedstock type, required plant size, and required input volume. The study also revealed that sanitary landfill with gas capture is the most suitable WTE technology for the Kwanwoma township based on the least set-up costs and scalability. The study provides the next steps for government action on WTE technology at the township, district, and national levels.
