Products & Services

LOW™ (Low-carbon Oxide from Waste) Circuit:A fully electrifiable process that extracts reactive alkaline minerals (CaO and MgO) from ore or tailings using mature thermochemical technologies for rapid scalability and integration into industrial processes.

ROC™ (Reactive Oxide to Carbonate) Circuit:A process that mineralizes CO₂ into stable carbonate minerals using low-carbon oxides from the LOW™ circuit, operating at atmospheric conditions for rapid conversion without separate capture steps.

Carbon Removal Credits:Auditable, permanent, scalable carbon credits with co-benefits, using CO₂-bearing minerals for site rehabilitation and reducing environmental risks from waste.
