Reinventing Cement

Main content start

Turning waste concrete into new cement while simultaneously lowering costs and emissions.

About the Technology

Almost all cement today is made from virgin limestone and clay which must be quarried and transported, and which releases CO2 as it’s made. Our technology upends this status quo by enabling the production of high-performance clinker from concrete waste using renewable power. By recycling existing concrete we make it possible to supply the construction industry while simultaneously lowering both emissions and costs.

Using electromagnetic induction to rapidly and uniformly heat materials from concrete waste triggers fast, high-temperature liquid-phase reactions that maintain performance characteristics while cutting energy use and cycle time. Put more simply: Our lab tests show we can make cement more cheaply and with fewer emissions, while simultaneously saving energy. Further, our process can be carried out in existing kilns in steel factories and other high-heat industries using energy from renewable sources, dramatically lowering initial capital costs and increasing scaling speed.

Working with the HIT Fund, we will identify a path to the market by strengthening use cases and identifying potential customers. We’ll also continue to refine our process to ensure industry standards are met, reducing risk.
