Abstract: In this paper, the Greenhouse Gas (GHG) emissions from an uncontrolled landfill site filled with Municipal Solid Waste (MSW) are compared with those from controlled sites in which collected Landfill Gases (LFG) are utilised by various technologies. These technologies include flaring, conventional electricity generation technologies such as Internal Combustion Engine (ICE) and Gas Turbine (GT) and an emerging technology, Solid Oxide Fuel Cell (SOFC). The results show that SOFC is the best option for reducing the GHG emissions among the studied technologies. In the case when SOFC is used, GHG emissions from the controlled site are reduced by 63% compared to the uncontrolled site. This case has a specific lifetime GHG emission of 2.38 tonnes CO₂ .eq/MWh when only electricity is produced and 1.12 tonnes CO₂.eq/MWh for a cogeneration application.
