Change (C4C) is a deep-tech R&D company pioneering a breakthrough technology to permanently mineralise CO₂ in concrete. Our innovation is globally recognised, winning awards from the United Nations, Royal Academy of Engineering, and the COP
26 Climate Challenge Cup. We are backed by industry giants Siam Cement Group and Goldbeck GmbH and work with top academic and industrial partners including the Universities of Nottingham, Leeds, Sheffield, Warwick, and manufacturers like Holcim, CRH, Marshalls, and Ibstock.
