The environmental and energy performances of the Italian municipal solid waste incineration (MSWI) system was investigated by a life cycle assessment approach. On average the 39 MSWIs operating in Italy in 2018 treated about 6,000,000 Mg of residual municipal solid waste (RMSW) recovering on average from 448 kWh Mg RMSW to 762 kWh Mg RMSW of electricity and from 732 kWh Mg RMSW to 1102 kWh Mg RMSW of heat. The average quantity of COeq Mg RMSW emitted ranged from about 800 up to about 1000 depending on the size and on the energy recovery scheme of the facility. Avoided impacts (i.e., negative values) were detected for the kg PM Mg RMSW and for human health (disability-adjusted life year Mg RMSW). The determination of the hybrid primary energy index (MJ Mg RMSW) indicated that mainly large size facilities and those operating according to a power and heat energy recovery scheme are effectively able to replace other primary energies by the exploitation of the lower heating values of the RMSW.
采用生命周期评价方法研究了意大利城市固体废物焚烧（MSWI）系统的环境和能源性能。2018 年，意大利平均有 39 座 MSWI 处理约 600 万吨剩余城市固体废物（RMSW），平均从 448 kWh Mg RMSW 到 762 kWh Mg RMSW 的电力和从 732 kWh Mg RMSW 到 1102 kWh Mg RMSW 的热能中回收。COeq Mg RMSW 的平均排放量约为 800 至 1000 公斤，具体取决于设施的规模和能源回收方案。对于 PM Mg RMSW 和人类健康（残疾调整生命年 Mg RMSW），检测到了避免的影响（即负值）。混合初级能源指数（MJ Mg RMSW）的确定表明，主要是大型设施和根据电力和热能回收方案运行的设施能够通过利用 RMSW 的低热值有效地替代其他主要能源。
