Abstract

Human activities create waste; the composition of solid waste varies from town to town and depends on food habits, cultural practices, occupations, and the presence and apes of industries and institutions. In Nigeria, only a little is known about the characteristics of solid wastes generated in institutions of higher learning. The study, therefore, characterized solid wastes generated in non-residential areas of the University of Ibadan. A cross-sectional study design was adopted. The non-residential areas of the Student Union Building (SUB), Works Department (WD), and Faculty of the Social Sciences (FSS) were purposively selected. Wastes generated in the three locations were weighed and their Physico-chemical characteristics determined using the Standard methods. Descriptive statistics were used to analyze data. The mean weekly recyclable wastes generated in the three locations were: 246.9+2 l.4kg (food wastes), 111.7+I 0.6kg (plastics), and 156.5+ 10.3kg (paper). The mean values of the chemical constituents or the generated food wastes were: 2.7+0.59, 2. I +0.77 and 3.4+0.72% (nitrogen) for SUB, WD, and FSS respectively with no significant difference; 0. I +0.03, 0. I +0.03 and 0.1 + 0.04% (phosphorus) for SUB, WD and FSS respective with no significant difference; and 0.3+0.04, 0.2+0.05 and 0.2+0.03% (potassium) for SUB, WD and FSS respectively and no significant difference was observed. The solid wastes generated in the non-residential areas have good recycling potential with a large volume. Therefore, efforts should be made for the establishment of a solid waste recycling facility in the Institution.
