Determination of the Composition of Waste and Estimation of Its Recoverable Energy Potential as an Essential Tool to Improve the Waste Management Plan: The Case Study of Nangui Abrogoua University in Côte d'Ivoire

Recoverable energy from waste is a major source of environmentally sustainable energy that is not currently unexplored in Cote d'Ivoire. This study evaluated the potential for energy recovery from waste, using waste produced at a university as a study model. It is the Nangui Abrogoua University. It was used as a study model because of its waste management system. The solid waste generated in this model has been characterized in its different components. The recoverable energy potential of the waste was then evaluated. The calorific value was used to predict the equivalent energy availability of the waste in kWh and equivalent tonnes of oil. The results of the study show a non-negligible energy potential that could reach 5687.1 MJ per day, i.e., 1579.8 kWh or 0.4 tonnes of petroleum equivalent per day. These results suggest the necessity to develop a waste management system impregnated with a policy of energy recovery from waste to supplement energy needs and obtain other social benefits from the implementation of such a policy.
