Phil Salter, a researcher at the University of Strathclyde, is establishing Ureaka to develop carbon-negative concrete technology. This approach aims to replace traditional cement with materials that securely store CO2.

Ureaka estimates its bioconcrete could prevent 14.8 megatonnes of CO2 emissions in the UK, equivalent to removing five million cars from the road for a year. Supported by Strathclyde's commercialization team and Scottish Enterprise, Ureaka has gained recognition as a finalist in the CarbonX Program 2.0 and is shortlisted for the 2026 Scottish Knowledge Exchange Awards.
