Abstract

Waste generation and disposal has today become a stern unruly in our dear country Nigeria and it has engrossed substantial curiosity among communities and government because of its multifaceted nature and associated economic, environmental and sociological glitches. This call for the need to understanding the rate and volume of waste generated is very imperative for environmental sustainability. This paper centered on the inventory analysis of solid waste generation and distribution in Ibadan Metropolis. The data used for this study were collected from Oyo State Waste Management Agency (OYOWMA) and Zero Intercept Polynomial Regression Model was used to study the pattern of waste generated and distribution in Ibadan, Oyo state. Shapiro-Wilk and Kolmogorov-Smirnov test were applied to test Normality Assumption. It is observed that the parameters in the model are statistically significant at 5% level of significance except for that of Abaeku. The adjusted R-Squared is 0.9854 indicates a high joint contribution of all the parameters to the response variable (Waste Generated). The ANOVA table shows the appropriateness of the Regression model used for the data, as almost all the parameters are significant. Since the p-values for the models are less than 0.05, the residuals generated from the models are normally distributed.
