TRAPPED IN CONCRETE
Across the world, over 9 billion tonnes of concrete is produced each year. Some CO 2 removal technologies are targeting this large-scale process by trapping the gas within concrete. When used by concrete producers, these machines inject captured CO2 into the concrete while it is being mixed. This causes the CO 2 to mineralise, meaning it becomes a solid mineral, like carbonate. As a solid mineral the carbon increases the overall strength of the concrete while preventing the CO2 from being released back into the atmosphere
