The disclosure provides for the integration of a CO-consuming process, such as a gas fermentation process, with a CO2 to CO conversion system. The disclosure is capable of utilizing a CO2-comprising gaseous substrate generated by an industrial process and provides for one or more removal modules to remove at least one constituent from a CO2-comprising gaseous substrate prior to passage of the gaseous substrate to a CO2 to CO conversion system. The disclosure may further comprise one or more pressure modules, one or more CO2 concentration modules, one or more O2 separation modules, and/or a water electrolysis module. Carbon conversion efficiency is increased by recycling CO2 produced by a CO-consuming process to the CO2 to CO conversion process.
