Turning waste
into a resource
The energy transition will require more critical minerals, and more mining. Yet mines produce large amounts of waste.
We turn mine waste (e.g. tailings) into a valuable feedstock for gigatonne-scale permanent CO2 removal. Our technology can be applied in versatile ways across several stages of the mining circuit, in both active and closed mines.
Supercharging
rocks
We supercharge the natural ability of ultramafic rock to capture and permanently store CO2. By using high-intensity energy bursts, we liberate the magnesium, which makes the tailings more reactive.
All-natural,
just way faster
Exposing the activated feedstock to air starts the natural process of carbon mineralization. As the tailings begin to react with atmospheric CO2, they develop more and more carbonated minerals. Once the surface layer is fully saturated, we expose fresh feedstock, to further accelerate and maximize carbon sequestration.
Quantifiable
and verifiable
Autonomous rovers continuously monitor and verify the rate and volume of carbon capture. Our advanced measuring and reporting technologies support third-party verification. Having a real-time picture of CO2 flux enables us to remotely direct the rovers’ Smart Churning counterparts for maximum efficacy.
Maximizing
carbon sequestration
Targeted Smart Churning further increases CO2 mineralization. Guided by a monitoring team, remote-controlled rovers churn the surface of the tailings, and expose fresh rock to atmospheric CO2.
