Karbonite

Decarbonising Cement. Scaling the Future of Construction. Cement is responsible for around 8% of global CO₂ emissions - more than aviation and shipping combined. Yet it remains the foundation of modern civilisation. At Karbonite, we believe the world doesn’t need to choose between progress and the planet. We’re building the bridge between the two. Karbonite is a green cement company developing ultra-low-carbon alternatives to traditional clinker-based cement. Our technology uses magnesium silicate–based supplementary cementitious materials (SCMs) and circular industrial by-products to achieve the same strength and performance as conventional cement - but with dramatically lower embodied carbon. We’re focused on turning cutting-edge material science into scalable industrial solutions. By aligning innovation with existing infrastructure and cost parity, we aim to make true decarbonisation commercially viable for the global construction industry. Our mission is simple: To prove that real climate solutions can scale when science, systems, and purpose align. Learn For partnerships or investment enquiries: info@karbonite.co.uk
