Solid waste disposal sites account for up to 20% of global emissions of methane the second most
significant greenhouse gas. However, under proper management landfills can in fact have a positive carbon
balance, by capturing the methane-rich landfill gas (LFG) produced from the dumpsites. This paper assesses
the potential for implementing such a project in the Olusosun waste disposal site in Lagos, Nigeria. Data
regarding municipal solid wastes (MSW) generation and composition, regulations as well as relevant aspects
of the Nigerian energy market and its regulations and climate change policies were evaluated. This is
employed to assess the potential for a viable implementation of a landfill gas to energy project at the site. The
analyses revealed that the flaring only scenario was observed to be the most economically feasible. The cost
