Feasibility study of the potential for landfill biogas from two landfills in the city of Freetown

Project description

STELLA has carried out a feasibility study of the potential for landfill biogas from two landfills (Kingtom and Kissy/Granville) in the city of Freetown, Sierra Leone. STELLA conducted two missions to Sierra Leone - one in December 2010 and another one in January 2011. During these missions, we collected information on the sites and measured the biogas that could be used for energy production. STELLA estimated the quantity of solid waste disposed of in the two sites and described the composition of solid waste in the two sites such as type and age of the waste. STELLA also assessed the environmental impact near the sites and prepared an environmental plan to minimise these impacts. Finally, STELLA proposed alternatives for extracting biogas from the two landfills and prepared an economic and financial analysis of the preferred alternative. This analysis quantified Greenhouse Gas (GHG) emissions, assessed the potential for producing methane and other gases and the electricity production capacity from landfill gas, and assessed the costs, benefits, and feasibility of registering this project as a Clean Development Mechanism (CDM) project. We also prepared a description and preliminary design of the preferred alternative for extracting biogas from the two landfills. The feasibility study confirmed that the two sites of Kingtom and Kissy could produce about 1.5 million m3 of biogas per year. However, biogas recovery from these two sites would be financially viable only if the projects can qualify as CDM under the United Nations Framework Convention on Climate Change (UNFCCC).
