Abstract
In this study, the multi-criteria analysis model is
demonstrated for evaluation and technologies from municipal
solid waste (MSW) in City of Johannesburg (CoJ), South
Africa. The technologies evaluation and alternation criteria for
multi-criteria decision analysis (MCDA) area characterized by
reviewing the literature and consulting experts in the
renewable energy and waste management. MCDA was the
approach employed by decision makers to make
recommendation on technique employed to select the most
suitable biogas digester technology for organic fraction of
municipal solid waste (OFMWS) originating from the city’s
landfills base on scalability, relative cost prices, available,
temperature regulation, agitation, ease of construction,
operation and maintenance. The result for digester type
indicated that the “complete mix, continuously stirred
anaerobic digester” (CSAD) was preferred with 79%
preference to other anaerobic digester technologies for energy
recovery.
