Abstract:
One of the most significant contributors to climate change are liquid fuels, creating a pressing need for alternatives. This study analyses the environmental impacts associated with producing Fischer-Tropsch (FT) fuels from municipal solid waste (MSW) via gasification. A cradle-to-gate life cycle assessment compared 4 production routes, direct and indirect gasification coupled with a solid oxide electrolyzer cell (SOEC) and water gas shift (WGS) reaction for hydrogen-carbon monoxide ratio correction. It is seen that direct gasification coupled with an SOEC has the lowest environmental impact among all 4 configurations, with the hotspots being the drying of the MSW and the hydrogen-carbon monoxide ratio correction steps. These results show that an optimized MSW to FT-fuel process can be a promising path to alternate liquid fuels.
