Carbon Capture
Pulverized rock dust spread on farmland has the potential to remove vast amounts of carbon dioxide from the atmosphere, helping countries meet their net-zero carbon target by 2050, experts say. In Britain alone, researchers believe that almost half of the nation’s CO2 removal goals could be achieved in this way.
Enhanced rock weathering is a process in which basalt and other rocks are ground up, increasing their surface area to better absorb carbon from the atmosphere. Because no new technology is needed to prepare, distribute and spread the rock dust, it is far more practical and cheaper than other forms of direct air capture and storage under development.
