Quantification and Characterization of Solid Waste for Optimal Management: A Case Study of Lead City University, Ibadan

Abstract

This study analyzed and characterized solid waste generated at Lead City University (LCU)
in Ibadan, with the purpose of evaluating waste disposal methods and identifying appropriate
strategies for achieving sustainable solid waste recycling and management. The sampling locations
for the two-month study period were chosen using a purposeful sampling technique. Data were
collected at the following locations: Boys Hostel, University Mosque, Cafeteria, Faculty of
Engineering, and College of Medicine. Plastics (35.21%) and Organic Waste (23.05%) accounted
for the majority of the solid waste generated. Polyethene bags, food packs, other wastes, paper,
metals, fabric, and e-waste represented 11.59%, 10.11%, 5.41%, 5.17%, 4.25%, 3.28% and 2.03%.
Also, recyclable, non-recyclable, and compostable wastes cover over 62, 14, and 24%, respectively
of the total waste generated at LCU during the 2-month sampling period. The total amount and
percentage of non-biodegradable materials (95 kg and 73%) was substantially higher than that of
biodegradable materials (35.3 kg and 27%). This characterization provides important information
about the types and amounts of waste items produced on the university campus. The findings of
this study provide valuable insights for improving solid waste management practices at Lead City
University and other similar institutions. Recommendations include implementing thorough waste
segregation programs, investing in recycling and composting facilities, and developing a
sustainable waste management strategy customized to the university's specific needs. Addressing
these issues is critical for establishing a cleaner and healthier environment on university campuses
and contributing to larger sustainability goals.
