Solid-Waste Quantification and Characterization in A Tertiary Institution in Southwest Nigeria: A Case Study of Lagos University Teaching Hospital (Luth) / College of Medicine of The University of Lagos

West Afr J Med. 2025 Aug 29;42(8):635-641.

ABSTRACT

BACKGROUND: Higher Education Institutions are expected to lead the paradigm shift in waste management by adopting strategies that will contribute to sustainable development in their operations. The impact of these innovations will expectedly diffuse to their surrounding communities. Waste composition studies in HEIs enables the identification of campus-specific opportunities for waste reduction and recycling. The aim of this study was to assess the quantity, composition of solid waste generated by the staff and students of the Lagos University Teaching Hospital and College of Medicine, University of Lagos (LUTH/CMUL) compound.

METHODS: The study was a descriptive cross-sectional study conducted in the LUTH/CMUL compound. Solid waste generated from the commercial, academic and research; administrative and residential areas were quantified and characterized during the study. Solid waste generated in the four activity areas collected were sorted, classified and weighed using a weighing balance.

RESULTS: An estimated 14.775 tonnes of waste is generated daily from the compound with a waste generation rate of 0.29/kg/capita/day. Plastic and polythene bags made up majority (31.1%) of the total solid waste generated in the compound followed by organic waste (23%). In the commercial area, organic waste (57.21%) formed majority of the waste, plastics formed the majority (22.95%) of the waste in the residential areas and paper waste was mostly generated in the administrative area (41.22%) and, the academic and research areas (36.10%).

CONCLUSION: The quantity and composition of the solid waste generated are affected by the activities ongoing in the different categorized areas. A solid waste management scheme hinged on a zero waste policy should be designed by the LUTH and CMUL authorities. This scheme should tackle reduction of waste at source, efficient waste collection from generation points, waste recovery, recycling and composting, proper training of stakeholders and provision of incentives.
