Environmental degradation due to pollution by solid wastes and the erratic power supply characterizing many urban areas in developing countries are the driving force of this study. The study explored possible energy bonus availability in various solid wastes based on their calorific values. Eight categories of solid waste, either heterogeneous or homogeneous in composition, were identified from University of Ibadan, an institution in South West Nigeria, with a population of over 30,000. These wastes were collected through purposive sampling and the moisture content and calorific values of the samples were determined using standard methods. Results of the study indicate that construction waste is the most beneficial heterogeneous waste with 18.58 MJ/Kg; the wooden component of the waste showed 15.73 MJ/Kg. Animal wastes, cassava peels from small scale community-based cassava processing mill and plant waste from lawns and gardens showed substantial energy, 18.12 MJ/Kg, 14.36 MJ/Kg and 14.19 MJ/Kg respectively. From heterogeneous municipal wastes, low density plastics or nylons, wood and paper showed calorific values of 25.20 MJ/Kg, 15.73 MJ/Kg and 13.14 MJ/Kg respectively. Plastics showed 10.91 MJ/Kg whereas concrete, metals and non-combustible materials showed no calorific value. Recommendations proffered by the study include a need to educate communities on the importance of waste separation before disposing and the adoption of waste-to-energy strategies as a sustainable source of energy bonus in institutions and a replicable model with example from a University community is proposed.
