This study proposes a multi-step approach to evaluating the environmental and economic aspects of a thermal treatment plant with an energy-recovery configuration. In order to validate the proposed approach, the Turin incineration plant was analyzed, and the potential of the incinerator and several different possible connections to the district heating network were then considered. Both local and global environmental balances were defined. The global-scale results provided information on carbon dioxide emissions, while the local-scale results were used as reference values for the implementation of a Gaussian model that could evaluate the actual concentrations of pollutants released into the atmosphere. The economic aspects were then analyzed, and a correspondence between the environmental and economic advantages defined. The results showed a high energy efficiency for the combined production of heat and electricity, and the opportunity to minimize environmental impacts by including cogeneration in a district heating scheme. This scheme showed an environmental advantage, whereas the electricity-only configuration showed an economic advantage. A change in the thermal energy price (specifically, to 40 €/MWh), however, would make it possible to obtain both environmental and economic advantages.
本研究提出了一种多步骤的方法来评估具有能量回收配置的热处理厂的环境和经济方面。为了验证所提出的方法，分析了都灵焚烧厂，并考虑了焚烧炉的潜力和与区域供热网的几种不同可能连接。定义了局部和全局环境平衡。全球规模的结果提供了二氧化碳排放信息，而局部规模的结果则用作高斯模型的参考值，该模型可评估释放到大气中的污染物的实际浓度。然后分析了经济方面，并定义了环境和经济优势之间的对应关系。结果表明，热电联产的能源效率很高，通过在区域供热方案中纳入热电联产，可以最大限度地减少环境影响。该方案显示出环境优势，而仅发电配置则显示出经济优势。然而，热能价格的变化（具体来说，为 40 欧元/MWh）将使得同时获得环境和经济优势成为可能。
