**4. Conclusions**

Although the waste collection system at Covenant University is very efficient and is evidenced by the clean environment, however, improvements are needed in terms of its waste collection times, component separation at points of collection, and final disposal systems. Waste generated by the university are representative of municipal wastes, and the proposed methodology from this study may apply at the local, state, and federal levels in an attempt to implement and drive governmen<sup>t</sup> policy on sustainable waste management.

Information on the characteristics of solid waste is important in evaluating systems, managemen<sup>t</sup> programs, and plans for reuse, reduction, recycling, and final disposal activities for solid waste management. From the survey carried out in this project, a total amount of N39, 834 (\$120 USD) per day can be obtained from the proper recycling of waste generated in residential areas. The highest amount can be obtained by plastic food packs with N16, 696.30 (\$50 USD), and the lowest by paper is N437.50 (\$1.5 USD).

From the survey carried out, it was observed that waste generation and characterization are dependent mostly on the products being supplied and sold in various areas of the University, such as the shopping mall, cafeteria, and others. In the students' halls of residence, it was observed that a sufficient amount of recyclable plastic packs and PET bottles were generated. Plastic packs from the halls of residence account for about 91.46% of the total PET bottles generated in the residential area, which is approximately 12.6% of the total waste generated in the residential areas. Food waste is the largest composition of the waste generated in the residential areas, accounting for about 52.40% of the total waste stream, with the staff residential areas contributing hugely to this at 96.48%.

The overall goal of solid waste managemen<sup>t</sup> is to collect, treat, and dispose waste. Conclusively, it can be said that more can be done to improve solid waste managemen<sup>t</sup> in Covenant University. Considering the amount of revenue that could be made from proper recycling, the University should make more investments in the purchase of recycling equipment for nylons, plastics, paper, and metals. The University can also partner with governmen<sup>t</sup> agencies and private organizations and take this functional system to the wider society, starting from the immediate local governmen<sup>t</sup> down to the state level.
