What if the answer to one of construction's biggest carbon problems wasn't a cleaner version of steel, but something else entirely? In this episode, Blue Earth founder Guy Hayler sits down with Stephan Savarese, co-founder of Technocarbon, to explore how an aerospace engineering mindset led to a breakthrough structural material made from stone and carbon fibre. They discuss why construction materials remain one of the least-talked-about sources of global emissions, how coastal infrastructure is quietly failing around the world, and what it takes to bring a deep-tech material from eight years of R&D to its first commercial orders. A conversation about patience, physics, and the scale of what's possible when you ask the right question.
