UK: Hanson has announced a 'carbon capture breakthrough' in its use of recycled concrete paste (RCP) in the wet scrubber of its Ribblesdale cement plant in Lancashire. In under 30 minutes, 15t of RCP was able to capture 1.5t of CO2 from the plant's flue emissions. Carbonated RCP is suitable to replace limestone in cement production.
Hanson's sustainability director Marian Garfield said “The trial was carried out with our parent company Heidelberg Materials’ research and development team, and marks another important milestone in our carbon capture journey."
