More precisely, Blue Planet’s technology permanently locks up to 440 kg of carbon dioxide (CO 2) in every tonne of aggregate produced. The limestone aggregate can then be combined with cement to produce high-quality, sustainable concrete.
This involved the use of Sulzer Chemtech’s innovative separation technology to support the development of an efficient and effective carbon capture unit to enable Blue Planet’s geomimetic ® process for carbon capture, utilisation, and storage (CCUS).īlue Planet’s technology combines carbon dioxide captured from emissions from heavy industries in solution with metal ions obtained from concrete or other industrial wastes, to obtain carbonate minerals and form synthetic limestone aggregate. The new strategic agreement follows the announcement of a technical collaboration between the two companies in 2021. The new strategic agreement builds on Sulzer Chemtech’s and Blue Planet’s technical collaboration, launched in 2021, and includes investment from Sulzer in Blue Planet’s latest funding round. The two companies are working together to commercialise a mineralisation process that permanently sequesters carbon emissions captured from emissions-heavy industries in aggregate form, which can then be used to offset the CO 2 footprint of cement, producing carbon-negative concrete. Sulzer Chemtech is strengthening its collaboration with Blue Planet to continue developing their carbon capture and storage (CCUS) technology.
