Rewind, a nature-powered carbon removal company, has launched the world’s first commercial deep mine carbon storage project, located 1.3 km underground in Georgia, a nation in the Caucasus region of the Black Sea’s coast.
The facility, DMS Georgia, marks the first time certified carbon credits will be issued through the preservation of plant-based carbon in naturally oxygen-free underground environments.
The milestone establishes a new global approach to scaling anoxic biomass storage, the company said, with its own low-energy, permanent carbon removal method. By preserving surplus plant matter in oxygen-free conditions that prevent decomposition, the company achieves geological permanence at a fraction of the cost of traditional carbon capture technologies.
Rewind’s process builds on the natural carbon cycle. Plants absorb carbon dioxide as they grow, then release it during decomposition. This global exchange circulates about 350 gigatonnes of CO₂ each year, compared with humanity’s 50 gigatonnes of annual emissions. Rewind interrupts this cycle by locking away plant matter before it decays, keeping carbon underground for thousands of years.
The method mirrors natural preservation sites such as the anoxic seabed of the Black Sea, where organic material and shipwrecks have remained intact for centuries. Deep mine storage is one of several strategies in Rewind’s anoxic storage portfolio, which also includes marine and sediment-based projects. The approach can be adapted to various geographies, making it globally scalable.

Located 1.3 km underground in western Georgia, DMS Georgia has already stored more than 400 tonnes of CO₂ equivalent, with volumes increasing daily. The first certified credits are expected in early 2026, and the site’s annual capacity is projected to reach 50,000 tonnes by 2027.
By 2030, Rewind aims to remove one million tonnes of carbon each year through a global network of deep mines, marine basins and other anoxic environments. Using existing infrastructure and logistics, the company says its system is among the most energy-efficient and deployable carbon removal solutions available.
