Exterra Carbon Solutions

Exterra is developing the first above-ground alternative to large-scale underground carbon storage. The process uses mineral waste from mining operations to transform CO2 into stable carbonate minerals safely and rapidly. The technology involves two main circuits, the first extracts reactive oxides and valuable byproducts from mineral waste with a low carbon footprint, and the second converts the reactive oxides into carbonates in a matter of hours. This uniquely positions Exterra at the intersection of carbon management, mineral waste management, and critical mineral production.
