Abstract

This study provides valuable insights into the waste composition, generation rates, and opportunities for improving the current solid management practices of a university campus in Sub-Saharan Africa. Representative points were selected within the campus to collect solid waste (SW). The SW were sampled following ASTM D5231-92. The quadrant method prescribed by ASTM D 6323 was used to reduce about 150 kg of collected waste to 50 kg. The SW samples were collected in triplicates and sorted manually to determine their composition. QGIS, a geographic information system was utilized to optimize waste collection efficiency, optimal collection points, and the number of waste bins. The average daily solid waste generation at FUTA was 952.3 kg, with polythene and paper waste constituting the largest proportions at 26 % and 24 %, respectively. The waste generation rate per capita was estimated at 0.046 kg per day. Remarkably, 81 % of the waste generated at FUTA has the potential for recycling. This offers a viable potential for promoting sustainable integrated solid waste management (SISWM). The study proposes optimising waste collection points from the initial 42 to 97, considering the proximity to buildings and transportation routes. The study did not consider fluctuations in waste generation rates and composition throughout the seasons, yet the data gathered is considered adequate for this initial survey. Lack of collaboration, adequate policies, funds, infrastructure, and political will are among the impediments to SISWM in FUTA. The introduction of colour-coded waste separation bins, and assigning different colours to specific waste types, can promote proper waste disposal and facilitate recycling. Also, engaging the university community through workshops and seminars can foster such behavioural change. Collaboration with local entrepreneurs and recycling centres is another essential aspect of this paradigm shift. Such partnerships can explore innovative solutions for upcycling polythene waste and create waste-to-wealth pathways. Initial challenges of an insufficient policy framework for university- small scale enterprises (SME) engagement and the lack of business growth models could be addressed by promoting relevant skill development and motivational tasking of the existing entrepreneurship faculty. By implementing the proposed strategies and embracing circular economy (CE) principles, FUTA can reduce its environmental impact, promote recycling, and foster a culture of sustainability and entrepreneurial value creation on campus and beyond.
