This episode explores a groundbreaking Swiss innovation that could revolutionise the construction industry. Join us as we delve into Neustark's pioneering method of turning concrete waste into a carbon sink, permanently removing CO2 from the atmosphere. Discover how this technology not only helps decarbonise the concrete industry but also increases the strength of concrete. We'll discuss the science behind the mineralisation process, the impact of Neustark's 22 operational plants in Switzerland and Germany, and their ambitious plans to scale up globally. Tune in to find out how Swiss ingenuity is paving the way for a more sustainable future in construction.
