The Carbonated Tailings Process (CTP) is an innovative method that captures CO₂ from the atmosphere and binds it chemically with mine tailings to form a stable, cement-like material. This material can then be used for safe underground backfilling or co-disposal with waste rock.
CTP provides a permanent storage solution for captured CO₂ by turning it into mineral carbonates. This not only removes greenhouse gases from the atmosphere but also offsets emissions from mining operations, helping the industry meet its climate targets.
Yes. The process has been successfully validated at TRL 6 (Technology Readiness Level), meaning it has been demonstrated in a relevant environment. A pilot plant is being implemented at the Boliden Garpenberg Mine in Sweden, using real tailings and process water.
CTP reduces tailings management costs by approximately 12%, eliminates the need for costly tailings dams, and allows mining companies to generate high-quality carbon credits that can be sold or used to offset their own emissions.
Once the CO₂ reacts with the tailings, it forms stable mineral compounds such as calcium carbonate (CaCO₃). These compounds are chemically inert and do not degrade over time, ensuring permanent carbon storage.
Yes. CTP is designed to meet all relevant environmental and mining regulations, including EU Extractive Waste Directives and global standards for tailings management. It also helps reduce permitting times by proactively addressing environmental liabilities.
Absolutely. The CTP solution is designed for modular scalability, and the long-term plan includes licensing the technology to mines globally or delivering it as a service in collaboration with major industrial partners.
