Hanson's Ribblesdale cement plant carbonates recycled concrete paste with CO2 emissions
22 November 2022UK: 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."
Canada: St Marys Cement, part of Brazil-based Votoronatim Cimentos, has installed a US$19.9m wet scrubber at its Bowmanville cement plant in Ontario. The installation will reduce the plant’s sulphur dioxide (SO2) emissions by 90%. The producer says it is the first wet scrubber installed at a cement plant in Canada.
Operations Manager Jim Storey said “This investment in technology to improve the plant’s environmental performance has proven to be effective in removing SO2 produced in the cement manufacturing process. We are also pleased that the scrubber was assembled on-site and installed by local Ontario contractors and crews during our annual scheduled plant shutdown.”
