Abstract
An assessment of potential biomass resources inNigeria for the production of methane and power
generation is presented in this paper. Nigeria, as an underdeveloped and populous country, needs
an uninterrupted source of energy. The country's energy problems have crippled large sectors of
the economy. The percentage of people connected to the national grid is 40%. These 40% experience
electricity supply failure on average 10–12 hours daily. Energy generation from municipal
solid waste (MSW) is an effective MSW management strategy. Yearly waste generation has
increased from 6,471 gigagrams (Gg) in 1959 to 26,600 Gg in 2015. This amount is projected to
reach 36,250 Gg per year by 2030. Methane emission for 2015 was 491 Gg, and it is projected to
reach 669 Gg in 2030. These values translate to 3.48 × 109 kilowatt hours (kWh) of electricity for
2015, with a projected 4.74 × 109 kWh by 2030. The revenue to be derived from the electricity
that is generated could have been US$365.04 × 106 for 2015, and it is estimated that it will reach
US$473.82 × 106 by 2030. It was found that methane emissions from MSW increased with time,
and capturing this gas for energy production will lead to a sustainable waste management.
