The aim of this study is to provide a complete energy, economic and environmental analysis of a waste to chemical process that treats a feed mixture composed of Refused Derived Fuel and Plasmix, transforming it into syngas. The process was implemented in the Aspen Plus® simulation environment, where also a sensitivity analysis returning the maximum value of humidity allowable in three different scenarios of waste mixture has been carried out. Moreover, an economic analysis has been performed in which, on the basis of capital expenditure, operating costs and revenues of the plant, Net Present Value (NPV) and Internal Rate of Return (IRR) has been assessed, finding a value of 599 M€ and 28% respectively. Finally, environmental analysis has been performed; a comparison between the carbon dioxide emissions of the case “as it is now” versus “how it could be” with the waste to chemical process implemented has been carried out in which it was calculated a saving of around 581 kt/y of CO₂ emitted in the atmosphere.

本研究的目的是对废物化学过程提供完整的能源、经济和环境分析，该过程处理由拒绝衍生燃料和 Plasmix 组成的进料混合物，将其转化为合成气。该过程是在 Aspen Plus® 模拟环境中实施的，其中还进行了灵敏度分析，返回了废物混合物三种不同情况下允许的最大湿度值。此外，还进行了一项经济分析，其中根据工厂的资本支出、运营成本和收入，评估了净现值 (NPV) 和内部收益率 (IRR)，得出的值为 5.99 亿€ 和 28% 分别。最后，进行了环境分析；₂排放到大气中。
