Cocoon Carbon: (United Kingdom) Global supplies of EAF slag are increasing as steel manufacturing shifts to electric-arc scrap recycling, but similar to blast furnace slag, EAF slag is inert when air-cooled, and the chemical composition of EAF slag means traditional granulation cannot achieve the cooling rates required to impart reactivity. At Cocoon, our patent-pending next-generation granulation technology transforms molten EAF slag into a reactive supplementary cementitious material, unlocking millions of tonnes of low-cost, low-carbon, cementitious materials for the cement and concrete industries.

Neocrete is proven in projects around New Zealand and South-East Asia and is now selling in the UK and EU. Neocrete was chosen by the Global Cement and Concrete Association in 2023 as one of four technologies with the potential to decarbonize the global industry. 

• Cemvision: (Sweden) Cemvision is on a mission to revolutionize the cement industry. Its first product line, Re-ment, includes cement binders produced using industrial residual products instead of virgin limestone. This allows Cemvision to avoid the majority of cement-related CO₂ emissions while also reducing the need for virgin material extraction. Beyond the innovative product itself, Cemvision has developed technology to electrify the production process, eliminating emissions typically responsible for 30–40% of total cement CO₂ emissions. 

• Sonocrete: (Germany) Sonocrete has developed a high-power ultrasound premixing stage for concrete production. In this premixer, we treat water, cement, and an SCM with high-power ultrasound before the concrete mixing starts. The ultrasound induces cavitation, which disperses all materials and helps C-S-H phases grow to accelerate the concrete hardening. This way, the amount of cement or cement clinker can be reduced, allowing producers to save carbon and cost.
