Waste Manag. 2021 May 1;126:597-607. doi: 10.1016/j.wasman.2021.03.035. Epub 2021 Apr 13.
The paper contributes to the debate concerning the management of municipal solid waste by providing an analysis of two key aspects of waste management - namely, waste separation and dispatch to treatment plants. Our analysis aims at detecting the extent to which actual behavior in (close-by) municipalities is similar with respect to those two aspects. To pursue our scope, a complex network approach is followed. In particular, we conceptualize, explore and compare two networks, whose nodes are the municipalities, while weights synthesize in one network the percentage of sorted waste that is collected at a municipal level, and in the other one the distance from the waste processing plants used by each municipality. The theoretical network models are implemented through an empirical study based on a high quality dataset referred to Italian municipalities. In this regard, the detection of communities of municipalities and their geospatial contextualization are introduced as devices for a complete description of current practices of municipal waste separation and transfers in Italy.
本文通过分析垃圾管理的两个关键方面——即废物分类和送往处理厂——为有关城市固体废物管理的辩论做出了贡献。我们的分析旨在检测（附近）城市在这两个方面的实际行为在多大程度上相似。为了实现我们的研究范围，我们采用了复杂网络方法。具体来说，我们将概念化、探索和比较两个网络，其节点是城市，而权重在一个网络中综合了每个城市收集的分类废物的百分比，在另一个网络中综合了每个城市使用的废物处理厂的距离。理论网络模型通过基于意大利城市的高质量数据集的实证研究来实现。在这方面，引入了检测城市社区及其地理空间背景化的方法，以全面描述意大利当前的城市废物分类和转移实践。
