Solid Waste Management Practices at a Private Institution of Higher Learning in Nigeria

Abstract

Waste generation is an intrinsic part of human existence. Waste materials are usually characterized by their nature, components and quality. Variations in quality, quantity and composition of solid waste can be linked to various factors such as cultural, economic, social and financial status of inhabitants of the particular space being studied. These distinct factors will also determine the best waste management practice to adopt. This paper captures the current institutional solid waste management in a Nigerian Private institution of higher learning. Using key-informant interview and personal field observations, the waste generation rate, pattern and characterization was made. Results showed that between 0.3 and 0.4kg/capita/day was generated daily by the students in their respective halls of residence, with population ranging from 762 – 848 students in each of the halls. All the solid wastes generated were collected using appropriate waste collection bags and mobile bin positioned at strategic corners of the university premises. The waste materials after collection were segregated into plastics, bottles, nylon and organic materials by scavengers. After these non-bidegradables were sold in the secondary market, an estimated total sum of 639,900 naira (2908.6USD) was realized daily. At this rate a total sum of 230 million Naira (1,045,454.5 USD) is realizable yearly as wealth from waste. It was concluded that if all the organic waste streams from kitchens, cafeteria and animal houses are utilized for bioenergy and organic fertilizer, the wealth to be generated would be phenomenal.
