LCA as a decision-supporting tool in planning integrated municipal solid waste management is not, as yet, widely used in Italy. This paper presents a study concerning the application of the LCA methodology to support the development of the new waste management plan for the Bologna District. The main goal of the study was to show decision-makers at the political level the benefits obtainable with the use of LCA, in terms of the identification and quantification of the potential environmental impacts of different waste management strategies. The integrated waste management system of the Bologna District includes waste collection and transport, sorting, recycling, composting, incineration and landfilling. Three scenarios, referring to 2006 and assuming the presence of 950,000 inhabitants and the production of approximately 566,000 t of waste in the district, have been compared. A detailed model has been developed in order to capture effects related to the waste fraction from separated collection and to the different waste treatments. The discussion of the results has focussed in particular on the greenhouse effect and the acidification potential. On the basis of the results obtained, the analysis of an additional scenario characterised by a further increase in separated collection has been put forward.
生命周期评估作为城市固体废弃物综合管理规划中的一种决策支持工具，在意大利尚未得到广泛应用。本文介绍了一项关于应用生命周期评估方法来支持博洛尼亚地区新的废弃物管理计划制定的研究。该研究的主要目标是向政治层面的决策者展示使用生命周期评估的益处，即在识别和量化不同废弃物管理策略的潜在环境影响方面的益处。博洛尼亚地区的综合废弃物管理系统包括废弃物收集与运输、分类、回收利用、堆肥、焚烧和填埋。已对三种情景进行了比较，这些情景参照2006年，假设该地区有95万居民且产生约56.6万吨废弃物。已开发出一个详细模型，以捕捉与分类收集的废弃物部分以及不同废弃物处理方式相关的影响。结果讨论尤其聚焦于温室效应和酸化潜力。基于所获结果，提出了以进一步增加分类收集为特征的另一种情景分析。
