The effect of volume reduction methods on beverage packaging waste recycling in the deposit return system

This study examines the environmental and economic implications of volume reduction techniques applied to beverage packaging waste within deposit return systems (DRSs). The research evaluates methods such as compression, crushing, and cutting, focusing on their Effectiveness in reducing the volume of plastic, glass, metal, and composite containers. The findings indicate that these techniques substantially reduce container volumes, with cutting and shredding proving particularly effective for metal and aluminum cans. Specifically, the cost of transporting one ton of plastic containers over 100 km is reduced by 73%, while transportation costs for metal and aluminum containers decrease by 50%. From an environmental perspective, volume reduction methods significantly contribute to sustainability by minimizing vehicle emissions and optimizing transportation demands. Economically, these techniques enhance logistical efficiency and lead to substantial reductions in operational costs, thereby reinforcing the overall efficacy and viability of DRSs. The study's results offer actionable insights for policymakers seeking to optimize recycling systems through regulatory frameworks that incorporate volume reduction practices. Moreover, the findings reveal opportunities for industries to implement these techniques, ensuring alignment with circular economy principles and regulatory mandates. These contributions underscore the critical role of volume reduction methods in enhancing both the environmental and economic outcomes of recycling processes within DRSs.
