In the last decade, the approach to waste management has undergone severe changes. The urgent need to face the sustainable demand for energy and materials while limiting the burdens associated to traditional waste handling practices have figured out the concept of waste as a resource. New strategies boosting the extensive recovery and diverting waste from disposal activities have been promoted and framed in the wider context of the urban mining, promoting the full exploitation of waste as resource for either new materials or energy production. Such approach has been recently proposed to handle over 5 million tons of pretreated municipal solid waste produced and stored in the form of bales in Campania Region, in southern Italy, between 2000 and 2009. However, since the feasibility of this approach is related to the waste composition as well as to the selection process, an experimental study was performed at an industrial mechanical treatment plant to assess the potential for valorisation of this waste. Results showed that the overall sustainability of the urban mining strategies for the management of Campania waste bales is tightly linked to the flexibility of the selection process scheme to be adopted, which should make the waste recovery fit the market demand of either material or energy.
在过去的十年中，废物管理方法发生了重大变化。面对能源和材料的可持续需求，同时限制传统废物处理方式带来的负担，人们将废物视为一种资源。新的策略促进了广泛的回收利用，将废物从处置活动中转移出来，并在城市采矿的更广泛背景下得到了推广，以充分利用废物作为新材料或能源生产的资源。这种方法最近被提议用于处理意大利南部坎帕尼亚地区 2000 年至 2009 年间以捆装形式储存的 500 多万吨预处理城市固体废物。然而，由于这种方法的可行性与废物成分以及选择过程有关，因此在一家工业机械处理厂进行了一项实验研究，以评估这种废物的增值潜力。研究结果表明，坎帕尼亚废物捆的城市采矿管理策略的整体可持续性与所采用的选择过程方案的灵活性密切相关，该方案应使废物回收适应材料或能源的市场需求。
