Fossil-Free Polyethylene and Polypropylene Production via CCU and Biomass Pathways: A Harmonized Techno-Economic Assessment.

ABSTRACT: The transition to a fully sustainable chemical industry requires new technologies and value chains, where fossil fuels are replaced as both energy source and carbon feedstock. To identify the key metrics that will make the transition viable, we developed a modeling framework for techno-economic assessment and applied it in a case study of co-manufacturing polyethylene and polypropylene from sustainable sources of carbon, viz. captured carbon utilization and biomass pathways. Differently from existing literature, our modeling framework bridges user-defined economic parameters, thermodynamic-based process models, and process performance assessment consistently throughout the different pathways. In this manner, the process designs and economic assessment are harmonized in assumption and scope
