Sustainable waste management presents a critical global challenge, necessitating the development of strategies for waste reduction and enhanced recycling. This study explores the impact of pay-as-you-throw tariffs (PAYTT) on promoting sustainable urban waste management. Propensity score matching was employed to analyse data from 7583 Italian municipalities. The study assesses the effects of PAYTT on both total and unsorted urban waste and evaluates their influence on the quantity and quality of separate waste collection. The findings indicate that the implementation of PAYTT effectively aligns with EU waste hierarchy policies. Municipalities adopting PAYTT experience reduced total and unsorted waste generation, along with improved quantity and quality of separate waste collections. Consequently, PAYTT holds significant potential for widespread application throughout the EU, contributing to enhanced separate waste collection efforts.
可持续的废物管理是一个全球性的挑战，需要制定减少废物和加强回收的策略。本研究探讨了收费制（PAYTT）对促进可持续城市废物管理的影响。采用倾向评分匹配法对来自意大利 7583 个城市的数据进行了分析。本研究评估了 PAYTT 对城市总废物和未分类废物的影响，并评估了其对分类废物收集数量和质量的影响。研究结果表明，收费制的实施与欧盟废物分级政策相符。采用 PAYTT 的城市，其总废物和未分类废物的产生量有所减少，同时分类废物收集的数量和质量也得到了提高。因此，收费制在欧盟范围内具有广泛应用的潜力，有助于加强分类废物收集工作。
