Despite international commitment to achieving a 50 percent reduction in global illiteracy by 2015, progress remains slow as approximately 759 million adults, two-thirds of which are women still lack basic literacy skills. In Nigeria, various efforts and initiatives have been put in place by successive governments (from federal to local government) and nongovernmental organisations toward the development of adult literacy. However, the problem of illiteracy has negative implications on the populace, economy, and it continues to pose significant challenges to the country in the daily activities of people towards waste product disposal. This study, therefore, examines the development of literacy level, practice, and disposition of people towards indiscriminate waste disposal in Ibadan Metropolis, Nigeria. This study is a descriptive research design with the population consisted of all male and female adults in Ibadan metropolis across eleven Local Government Areas of Ibadan, Oyo State, Nigeria. Six hundred (600) (300 males and 300 females) were selected using stratified random sampling technique from two out of eleven Local Government Areas of Ibadan, Oyo State. The findings of the study revealed that there was a significant difference between the steps taken by the government and citizens towards indiscriminate waste disposal (t= 5.245; p<0.05). It was equally revealed that the effects of indiscriminate waste disposal have a great impact on people (t= 5.432; p<0.05). Moreover, it was also revealed that the level of literates education has a significant influence on indiscriminate waste disposal (t= 1.011; p<0.05). It was concluded that the level of education of the people influenced their attitude and their disposition to waste product disposal. Therefore, it is recommended that government should be actively and practically involved in educating people on early warning messages and awareness programmes through radio jingles, seminars, workshops, conferences, handbills on various ways of disposing waste product.
