Concrete4Change Trial with Heidelberg Materials UK - May 2025

‍

We’re excited to share a key milestone: Concrete4Change has successfully completed a trial in partnership with Heidelberg Materials UK, validating our CO₂-based material in real concrete mixes.

Our technology transforms CO₂ and calcium waste into a high value material that fits seamlessly into how cement and concrete are already made — no overhaul, no disruption, lower emission and lower cost concrete.

This collaboration is a critical step in our journey to scale up and deliver carbon-negative materials to one of the world’s most emissions-intensive industries.

Thank you to the Heidelberg Materials UK team for their partnership and technical support.
