Sweden: The Swedish Energy Agency has awarded US$12.5m to Boliden under its Industrial Leap initiative to support the development of a low-carbon cement alternative derived from iron-rich residual materials. The product allows for partial replacement of limestone in cement. Boliden is building an industrial demonstration plant to produce, test and verify the new material, which is based on byproducts from its own operations. Boliden estimates that the technology could cut value-chain emissions by around 600,000t/yr of CO₂ if fully implemented across its operations.
“Demonstrating innovative new technology to manufacture products with lower carbon emissions is fully in line with the purpose of the Industrial Leap. By reusing materials in new products instead of depositing them, the project also contributes to more circular use of materials,” said Klara Helstad, Deputy Head of the Department for Research, Innovation and Business Development at the Swedish Energy Agency.
