Use of carbon dioxide (CO2) as a chemical feedstock for bulk products would facilitate the transition to a carbon-neutral economy. While electrocatalytic methods for converting CO2 into commodity chemicals have been discovered, their technical limitations, the high costs of CO2 capture and required logistics make them uncompetitive with petrochemical-based manufacturing. Instead, we demonstrate that integrating CO2R as a means to recycle waste CO2 and regenerate feedstocks is both technically feasible and profitable in the current market. As a specific use case, integration of CO2R with copper catalysts into ethylene oxide production will simultaneously reduce operational costs and up to 80% of direct CO2 emissions. Based on our analysis of chemical manufacturing processes suitable for this type of CO2R retrofit, the approach has the potential to become a widely adapted and transformative decarbonization method across different industries, such as e.g. ammonia, synthetic fuels, cement and steel production.
