Creating value from carbon dioxide

Rather than treating CO₂ as a waste biproduct, the CEO of C4X Technologies says converting CO₂ into valuable products could dramatically reduce the timeline to net-zero

Wayne Song is the chief executive of C4X Technologies, a Chinese-Canadian CCUS company aiming to scale up and commercialise technology that can convert CO2 into useful, value-added products. Song spoke to Transition Economist about how the company’s technology could help China (where the company is known as Green Carbon Nanotech) accelerate its progress towards carbon neutrality. What is unique about the technology that C4X is developing? Wayne Song: CCUS is well-known but we have added another ‘C’ to the process for conversion—CCCUS. If you look at China’s original roadmap for CCUS, there is not really much about conversion. The U—utilisation—is still largely CO2 at the end of the day. Usin
