Evaluating the effectiveness, costs, and challenges of deposit return systems for beverage containers: A meta-analysis

This study conducts a comprehensive meta-analysis to evaluate the effectiveness, economic costs, and long-term sustainability of deposit return systems (DRS) for beverage containers across various countries. DRS are recognized as a critical strategy to enhance recycling rates, reduce environmental waste, and support the transition toward a circular economy. While empirical evidence from countries like Germany, Norway, and Lithuania indicates that DRS can achieve recycling rates exceeding 90%, challenges such as high setup costs, stakeholder resistance, policy inconsistency, and adaptability to market changes complicate their implementation and sustainability. The analysis synthesizes data from diverse geographic contexts, highlighting the factors that contribute to the success or failure of DRS, including public engagement, policy stability, technological adaptation, and effective stakeholder collaboration. The findings suggest that while DRS can provide substantial environmental and economic benefits, their long-term success is contingent upon sustained public participation, consistent policies, adaptability to market shifts, and robust stakeholder engagement. This study offers critical insights for policymakers, environmental advocates, and industry stakeholders seeking to optimize DRS as a tool for sustainable waste management.
