Plastic Waste Reduction Strategies for Urban Sustainability

Abstract

Plastic waste is one of the most pressing challenges for modern cities, threatening ecological balance, human health, and municipal service delivery. With increasing urban populations and rising consumption, cities are producing unprecedented levels of plastic waste that overwhelm existing waste management systems. This paper critically examines strategies for reducing plastic waste in urban contexts through a multi-pronged approach that integrates policy, technology, economics, and social behaviour. Drawing on global case studies, policy analysis, and sustainability theory, the paper evaluates the effectiveness of strategies such as source reduction, product redesign, extended producer responsibility (EPR), economic instruments, recycling innovations, and community-driven initiatives. Findings demonstrate that upstream interventions, especially preventive strategies like bans on single-use plastics and material redesign, offer the highest long-term impact. However, their success depends on complementary measures, including robust municipal infrastructure, citizen participation, and industry accountability. The study proposes an integrated framework for urban plastic waste reduction that emphasizes systemic collaboration across stakeholders.
