Abstract
Plastic waste has emerged as a major environmental challenge in rapidly urbanizing cities, particularly in developing countries. In Lagos, Nigeria, increasing consumption of plastic products combined with inadequate waste management systems has intensified environmental degradation, including drainage blockage, flooding, and pollution of urban spaces. This study examines the role of effective plastic waste management in promoting urban renewal and environmental restoration in Lagos. A qualitative approach was adopted using a Systematic Literature Review (SLR) to synthesize existing research on plastic waste management practices and their environmental implications. Twenty scholarly publications were initially identified, from which nine key studies were selected based on their relevance to plastic waste management, sustainability, and urban development in Lagos and comparable contexts. The analysis reveals that plastic waste significantly contributes to environmental deterioration through drainage obstruction, pollution of water bodies, and declining urban environmental quality. The review also identifies major barriers to effective waste management, including inadequate recycling infrastructure, poor waste segregation practices, limited public awareness, weak policy enforcement, and the marginalization of informal recycling networks. Despite these challenges, emerging strategies such as circular economy approaches, improved recycling systems, stronger regulatory frameworks, and increased community participation present viable pathways for reducing plastic pollution and enhancing urban environmental quality. The study concludes that strengthening plastic waste management systems can significantly support environmental sustainability, improve urban sanitation, and contribute to broader urban renewal initiatives in Lagos.
