Sirona builds modular Direct Air Capture systems that use solid sorbents to remove CO2 from the air, then hands the captured CO2 to partners who inject it into basalt rock for permanent mineralized storage. The company deploys projects in regions with renewable energy and storage capacity, using sensor-based measurement and third-party verification to sell carbon removal to organizations offsetting unavoidable emissions.
