Abstract

This study examines the extent to which increasing the number of recycling bins in public spaces can reduce waste generation and improve recycling rates in urban areas, with a focus on the Four Seasons Garden community in Shanghai’s Pudong New Area. Through a mixed-methods approach combining field surveys, GIS spatial analysis, and case comparisons, the research evaluates the impact of bin placement, accessibility, and public engagement on recycling behavior. Findings indicate that while additional recycling bins enhance convenience and encourage waste sorting, their effectiveness depends on strategic placement in high-traffic areas, public awareness campaigns, and active community involvement. The study also highlights the potential of smart waste bins equipped with IoT technology to optimize collection efficiency and support sustainable urban development. However, limitations such as small sample size and subjective usage assessments suggest the need for broader, technology-enhanced future research. The results underscore the importance of integrating infrastructure improvements with behavioral and policy interventions to maximize recycling outcomes in smart cities and circular economies.
