Sulzer and Blue Planet in new push for carbon-negative concrete
Companies seek commercialisation of mineralisation technology to store carbon in limestone aggregate
Swiss engineering company Sulzer and US carbon management firm Blue Planet have agreed to work together to commercialise a mineralisation process developed by Blue Planet to permanently store emissions in aggregate form. Blue Planet’s technology combines captured CO₂ with industrial waste to make synthetic limestone aggregate—one of the three key ingredients of concrete. The technology permanently locks up to 440kg CO₂ in every ton of aggregate produced. “As a result, it is possible to completely offset the CO₂ footprint of cement and produce carbon-negative concrete,” the two companies say. 7pc – Share of global emissions from concrete production “Our collaboration with Blue Planet
