About ICELITH™ /ˈaɪs.lɪθ/
As Europe accelerates its green transition, two rapidly growing waste streams from renewable energy and infrastructure remain largely unutilized. ICELITH™ aims to transform these by-products into synthetic calcium silicate—a material both scarce and strategically valuable in the European market.
​
Through a patent-pending process powered by geothermal or hydropower, ICELITH™ produces a COâ‚‚-reactive mineral engineered for long-term carbon storage. This innovation has the potential to drive measurable decarbonization across concrete, agriculture, soil, and turf applications.
Turning Minerals into Carbon Sinks
Enhanced weathering is a natural carbon capture process in which silicate minerals react with atmospheric COâ‚‚ and moisture to form stable carbonate minerals, locking carbon away for geological timescales.
​
ICELITH™ aims to industrialize and accelerate this process by engineering synthetic calcium–silicate minerals with controlled composition, surface area, and reactivity. By optimizing these properties, ICELITH™ can significantly increase the rate of COâ‚‚ uptake compared with natural rock weathering, enabling measurable and verifiable carbon sequestration.
​
The goal is to integrate this approach into agriculture, soil restoration, and built-environment applications, turning ordinary materials into active tools for permanent, nature-based carbon removal.
