The Environmental Life Cycle Costing (LCC) methodology was applied to assess the costs of the processing in Italy of municipal Residual Waste (RW) in Mechanical-Biological Treatment (MBT) plants aimed at the production of Solid Recovered Fuels (SRFs), delivered to dedicated waste-to-energy (WTE) plants or to co-combustion. Two different functional units were defined to consider two different perspectives: 1 tonne of residual waste in input of the MBT plant, and 1 MWh of exergy produced by the energy valorisation of the streams delivered by the MBT plant. Four strategies were analysed that differ for the type of MBT (single stream or separated streams) and the destiny of the SRF (dedicated WTE plant or cement kiln). The results appear to strongly recommend the treatment of the RW in a single stream MBT plant and the production of a SRF with characteristics suitable to meet the technological, economic and environmental needs for co-combustion, substituting fossil fuels.
环境生命周期成本核算 (LCC) 方法被应用于评估意大利将城市剩余废物 (RW) 在机械-生物处理 (MBT) 厂进行加工的成本，这些废物的目标是生产固体回收燃料 (SRF)，并输送到专用的废物能源化 (WTE) 厂或共燃。为了考虑两种不同的观点，定义了两个不同的功能单位：1 吨输入 MBT 厂的剩余废物，以及 1 MWh 的 exergy 通过 MBT 厂输送的流的能源增值产生。分析了四种策略，它们因 MBT 的类型（单流或分流）和 SRF 的命运（专用 WTE 厂或水泥窑）而异。结果似乎强烈推荐将 RW 在单流 MBT 厂进行处理，并生产出具有适合满足共燃的技术、经济和环境需求的特征的 SRF，以替代化石燃料。
