UK Startup Turns Steel Plant Waste into Sustainable Concrete

The Challenge of Decarbonizing Steel

• The global steel and construction sectors are actively working towards decarbonization, including a shift to greener electric arc furnaces (EAF).
• ⚠️ Even with greener processes, a challenge remains in recycling the byproduct generated by these new electric furnaces.

Cocoon's Innovative Solution

• 💡 UK startup Cocoon has developed a method to transform waste from EAFs into a component for sustainable concrete.
• ⚙️ Their system cools EAF slag in a special mold, controlling heat loss to create a glass-like material.
• 🔬 This glass is then ground down and added to cement, acting as a replacement for traditional cement.

Benefits for Concrete and Cement Producers

• 🌱 Cocoon's process allows the EAF slag to have the same chemical properties as the waste from older blast furnaces.
• 🧱 This enables concrete and cement producers to use a sustainable alternative, addressing the growing demand for sustainable construction.
• 🤝 The modular system reconnects the steel and construction industries, fostering a more circular economy.

Environmental Impact and CO2 Reduction

• 🌍 The resulting concrete can reduce the amount of cement used by 30% to 50%, while also adding strength.
• ♻️ This method not only utilizes a byproduct but also encapsulates more CO2.
• 📈 Material Processing Institute supports Cocoon, highlighting that the product is 30% more beneficial to the environment than conventional alternatives, contributing to global CO2 impact reduction in steelmaking and construction.
