An Exploration of the Feasibility of Using Plastic Waste for Sustainable Road Construction in Nigeria: A Qualitative Approach
Researchers explored the feasibility of incorporating plastic waste into road construction in Nigeria using a qualitative approach, identifying socioeconomic, regulatory, and technical factors that could promote or hinder adoption. Findings suggest that leveraging Nigeria's large plastic waste stream for paving could address both waste management deficits and the country's severely underdeveloped road network.
Plastic Pollution in the Environment in Nigeria: A Rapid Systematic Review of the Sources, Distribution, Research Gaps and Policy Needs
This systematic review examines plastic pollution across Nigeria's environment, including water, soil, air, and food. The research finds that plastic contamination is widespread but under-studied in African countries, with significant gaps in data and policy. Understanding plastic pollution in developing nations is critical because these regions often lack the waste management infrastructure to prevent microplastic contamination of food and water.

This study used computational fluid dynamics analysis to redesign a microplastic water sampling device, improving its hydrodynamic performance and collection efficiency to address the lack of standardized sampling equipment for environmental microplastic monitoring.
Ensuring sustainability in plastics use in Africa: consumption, waste generation, and projections
This review examines plastic consumption, waste generation, and future projections for African nations, finding rapidly increasing plastic use alongside limited waste management infrastructure. The study calls for African-specific sustainability policies to prevent a major escalation in plastic pollution as economic development accelerates across the continent.
Plastic Pollution and Framework Towards Sustainable Plastic Waste Management in Nigeria: Case Study
Nigeria faces a growing plastic pollution crisis driven by the rapid expansion of companies producing plastic bottles and sachet water packaging. This paper examines the scale of the problem and proposes a framework for more sustainable plastic waste management, drawing on case studies of existing challenges and potential interventions. While focused on policy and waste management rather than microplastics specifically, reducing plastic waste at source directly limits the amount that fragments into environmental microplastics.
Global Plastic Pollution and the Nigerian Dimensions
This review examines global plastic pollution trends with a focus on Nigeria, covering plastic production history, environmental distribution, ecological effects, and policy challenges in the West African context. The authors document how weak waste management infrastructure and high plastic consumption growth rates make Nigeria particularly vulnerable to microplastic pollution in rivers, coastlines, and food chains.
Progress and future perspectives of microplastic research in Nigeria
This review summarizes the state of microplastic research in Nigeria as of 2019-2020, noting detection in rivers, lagoons, and coastal waters, and highlighting the limited research capacity and funding constraining progress in this important but underrepresented region.
