The paper illustrates a model to support waste management (WM) operators of municipal solid waste (MSW) services. This study proposes a framework to evaluate the potential of preparation for reuse (PfR) as strategy to jointly decrease social, environmental and economic impacts and meet the legal targets on waste management. As general indicators to evaluate the reusability of products do not exist yet, the aim of this study is the definition of a comprehensive indicator, which may be calculated for each product category by waste collection operators. The proposed reusability indicator includes one coefficient evaluating the potential for reuse, and three impact indicators for the assessment of social, environmental and economic performances. The indicator can be calculated by using real data, gathered by the waste collection operators in collaboration with reuse centres and referred to previous years. Hence, the proposed methodology allows waste collection operators to evaluate the potential consequences of the reuse strategy on their MSW collection system to monitor and disclose to public the impacts related to reuse activities, facilitating the achievement of sustainability in the WM sector.

城市固体废物收集系统：评估产品可重复使用性的指标

本文阐述了一种支持城市固体废物 (MSW) 服务的废物管理 (WM) 运营商的模型。本研究提出了一个评估再利用准备 (PfR) 潜力的框架，作为共同减少社会、环境和经济影响并满足废物管理法律目标的战略。由于尚不存在评估产品可重复使用性的通用指标，本研究的目的是定义一个综合指标，可由垃圾收集经营者为每个产品类别计算。拟议的可再用性指标包括一个评估再利用潜力的系数，以及三个用于评估社会、环境和经济绩效的影响指标。该指标可以通过使用真实数据来计算，由废物收集运营商与再利用中心合作收集并参考前几年。因此，提议的方法允许废物收集运营商评估再利用策略对其 MSW 收集系统的潜在后果，以监测和向公众披露与再利用活动相关的影响，促进 WM 部门实现可持续性。
