Phil Salter is launching Ureaka to create carbon-negative construction materials by integrating carbon capture with concrete technology. The new material aims to replace traditional cement and can sequester CO2 from industrial sources.

Ureaka estimates that replacing all concrete in the UK with its bioconcrete could avoid producing 14.8 megatonnes of CO2. The company has gained recognition in the CarbonX Program 2.0 and received funding from Scottish Enterprise.

Ureaka is also developing solutions for existing concrete repairs and new construction projects. The company has been shortlisted for the 2026 Scottish Knowledge Exchange Awards.
