This paper studies the potential of waste to biogas process in Nigerian universities using six universities across each of the geopolitical zones for the analysis. Despite signing the Abuja declaration in 2009 on the role of higher education in sustainable development in Africa. Nigerian universities are yet to fully commit to improving their waste management techniques. Waste to biogas will help to remove waste from the environment and serve as a source of energy generation and internal revenue for the tertiary institutions. Mathematical methods were used to estimate the potential biogas yield from the organic fraction of municipal solid waste and sewage from the six universities. Results showed an average potential value of 275,233.00 m3 of biogas from municipal solid waste organic fraction which can be converted into generation of 1,651.40 MWh. Results from the sewage conversion gave an average potential value of 258.46 m3 which is very low compared to the value that can be derived from the organic fraction of municipal solid waste. Biogas generation potential was observed to increase with population across the institutions.
