Thus, the practical possibility to use MSW to generate electricity should be evaluated. This paper presents a prefeasibility study aiming to identify the better waste-to-energy technology to be implemented in Accra, the capital city of Ghana. The performance of landfill gas (LFG) and waste incineration (WI) technologies were compared, via technical-economic simulation of the corresponding Net GHG Reduction (tCO2/yr), Electricity Exported (MWh/yr), Net Present Value (NPV) in USD and Internal Rate of Return (IRR) in %. The possible social benefits from the implementation of these technologies are also discussed. Key words: Landfill, Waste Incineration, Electricity Production, Municipal Waste, Ghana 1 INTRODUCTION Municipal Solid Waste (MSW) disposal in most developing countries around the world poses major environmental problems. Some problems arising from the bad collection and bad disposal of solid waste disposal include bad odor, airborne diseases, and waterborne diseases. To face the future problems in waste management, and to meet the demands of renewable energy resources, it is important that the waste is converted into energy. There are several technologies that can be used to produce energy from waste, such as engineered landfilling and incineration. Accra is Ghana's largest city with a population of approximately 3,909,764 (Ghana Statistical Service, 2011). Waste management problems in Ghana can be well understood in the light of rapid urbanization in its cities. As the economic situation improves, with Accra constituting approximately 10% of the total GDP of US$ 37.481 billion in 2010, the concerns for waste management rises since a stronger economy often leads to an increased waste production due to a higher purchasing power. About 1,800 tons of MSW are generated per day in the metropolis, although the collection capacity is only approximately 1200 tons (66%). The waste that is collected undergoes controlled dumping. The solid waste that is not collected is indiscriminately dumped in rivers and gutters, or burned. The composition of domestic waste in Accra is explained in Table 1. Policies that guide the management of solid waste include:  National Environmental Quality Guidelines (1998)  Ghana Landfills Guidelines (2002)  Manual for the preparation of district waste management plans in Ghana (2002)
