EQUIPMENTS AND MATERIALS
54 tonne of cement can absorb up to 0.6 tonnes of CO2 ( compared with each tonne of old style cement emitting about 0.4 tonnes ).
Carbon Clean , which now has proven scale across 10 locations , including the UK , India , US and Germany , uses an integrated modular system that works using rotating packed beds ( RPBs ) to intensify the carbon capture process .
This technology could provide a significant reduction in both capital cost and equipment size , when compared to traditional capture technologies , enabling the wider-scale commercial deployment of carbon capture systems . The technology will be tested for the first time in the cement industry at a CEMEX facility by deploying an industrial-scale pilot during the first quarter of 2021 .
Hanson ’ s range of sustainable concretes , including EcoPlus , are available from all static and mobile production plants . EcoPlus concrete mix with 70 % Regen Ground Granulated Blast Furnace Slag ( GGBS ) was used in the turbine bases at the Clyde Wind Farm adding sustainability and durability .
Replacing one tonne of Portland Cement with one tonne of Regen in EcoPlus concrete reduces the embodied CO2 by around 850kg . EcoPlus Regen ’ s applications are fairly broad too , covering foundations , pavements , structures and bespoke mixes ; it ’ s been used in the ‘ Walkie Talkie ’ building in central London – which has an 80.2 percent BREEAM rating – and a 20-storey building in Canary Wharf .
