The supercritical carbon dioxide process uses carbon dioxide under high pressure and temperature to remove caffeine from the beans. It might sound technical and seven days in liquid CO₂ sounds extreme, but it’s one of the cleaner and more efficient ways of producing decaf and is used more widely than you might expect. | James Hoffmann

#China's first million-tonne near-zero-carbon steel production line began full-capacity operation – a major breakthrough in the steel industry's low-carbon transition. The line uses hydrogen-based reduction and electric smelting, replacing traditional coke to cut carbon emissions. Compared to conventional methods, this new process reduces emissions by 50 to 80 percent. It offers a new pathway for China's steel industry to reduce its dependence on fossil fuels. #cgtnreels | CGTN
