| Abstract | 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 (R) 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 euro 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 CO emitted in the atmosphere. |
