This study assessed the amount of municipal solid waste generated in the University of Benin, Benin City, Nigeria. Direct waste analysis and a site-specific study were carried out to collect waste characterization data and determine the overall quantity of waste generated and components of the municipal solid waste in the campus. To help obtain the data for the study on a regional basis, areas were selected from residential, commercial and institutional centres to determine the total weekly generation of waste, average daily generation rate of waste and composition of waste. Results obtained revealed that average daily waste generation rate in the University of Benin was 0.455 kg/person/day which translates to 25,643.8 kg of municipal solid waste per day (per the estimated current population of over 56,360) generated in the University of Benin, from daily residential, commercial and institutional activities. Furthermore, characterization analysis of the collected waste samples showed that the municipal solid waste generated composed of 30.22% organic waste, 26.67% plastics/rubber waste, 18.65% paper, 11.08% metals, 3.70% miscellaneous, 3.10% inert, 2.39% glass/ceramics, 2.18% textile, 1.03% electronics and 0.98% leather waste. The results obtained suggests that there is a high potential for recycling, composting, biogas production and waste to energy in the University of Benin.
