Expanded Polystyrene (EPS) also referred to as Styrofoam, is a form of plastic frequently use for food packaging. This research focuses on the generation, disposal, and negative effects of waste EPS in Lagos Municipal Solid Waste (MSW). Studies from some specific locations in five Local Government Areas (LGAs) of Lagos showed daily usage of EPS (as food package) by street food vendors and its negative impact on the environment and human life. Qualitative analysis of these locations of Lagos state has shown how several factors including the properties of EPS such as low cost, light weight, versatility, low recycle value and non biodegradability has contributed to the surge of EPS waste in Lagos state. This paper shows how street food vendors and consumers’ attitudes have contributed to defacing the aesthetic quality of Lagos state.
