ABSTRACT

The management of municipal solid waste (MSW) appears as a challenge for many countries in the world. The rapidly increasing amounts of waste and the consequent potential impacts necessitate proper planning and management This paper assesses the management of the MSW in Oyo Township with the main objective of evaluating the physical and chemical constituents of the wastes and determine their best disposal method using GaBi6 Software. In this study, wastes were collected and their composition determined over a period of two months for each of Oyo west and east LGA. The waste data acquired was simulated using GaBi6 software for Landfilling and Incineration scenarios. The scenarios were compared through the CML and the Tool for the Reduction and Assessment of Chemical and other Environmental Impacts (TRACI) methods and these comparisons were carried out from impact measurement of: Global Warming Potential (GWP), Acidification Potential (AP), Eutrophication Potential (EP) and Ozone layer Depletion Potential (ODP). The results of the analysis showed that the per capita waste generation in Oyo west LGA and Oyo East LGA is 1.25 and 1.67 kg/capita/day respectively. Portable gas detectors were used to detect and measure the gases present at selected dumpsite. The detection of 700 ppm and 1100 ppm of CO2 before and after burning portrayed the effect of open dumpsite and open burning respectively. According to the comparisons and leachate analysis, landfilling scenario is the more environmentally preferable and is the best option to achieve sustainable solid waste management; it is therefore recommended for use in Oyo Township. Suffice to note, in this study waste management alternatives were investigated only on an environmental point of view. For that reason, it might be supported with other decision-making tools that consider the economic and social effects of solid waste management.
