A combined team of researchers from the University of Lyon and the University of Turin has developed a way to use waste CO2 to separate metals used in products. In their paper published in the journal Nature Chemistry, the group describes their process and why they believe it can be used as a global warming mitigation tool.

Scientists have promoted the idea of using carbon capture and storage (CCS) as a way to reduce the amount of CO2 emitted into the atmosphere. CCS involves capturing the exhaust from a car or a factory, removing the CO2 and then storing it until scientists develop a use for it.

CCS - Use - Effort - Researchers - Way

Unfortunately, CCS has proven to be too expensive for commercial use. In this new effort, the researchers developed a way to use waste CO2 to create ligands for separating metals from ores. The recovered metals can then be sold for use in making products such as smartphone components. Their idea is to recoup the cost of capturing CO2 (or make it profitable) so that businesses will find it more economically viable....
