Abstract: The main objective of this study was out to characterize and determine the energy potential of municipal solid waste (MSW) in Ibadan, South-West Nigeria. A total of 226 households and four major dumpsites from four different local government areas were sampled. Results obtained showed that waste generation rate in Ibadan metropolis was 0.63 kg/capita/day. From sampled households, through sorting and physical characteristics, MSWs were composed of food waste (53.53%), paper (23.22%), plastics (8.94%), wood (4.35%), rubber (2.22%), polythene (1.66%) and textile (1.66%). The calorific value was determined to calculate its energy content and potentials. Calorific value of 12.6 MJ/Kg was obtained using the modified Dulong equation which is greater than the benchmark for assessing electricity potential from MSW. An estimated 1,124.7 tons/day of MSW generated in 2013 translates to an energy potential of 3.6 GWh and 45.5 MW of electrical power potential capable of supplying 122.9*10⁶ households outside of the national grid. With appropriate technology, MSW has great energy potentials.
