Summary

Rewind cleans CO₂ from the atmosphere by relocating residual plants to the deep Black Sea. This is a nature-based approach, as all rivers wash organic carbon out to sea, and the Black Sea is the world’s largest anoxic basin, naturally preserving carbon for thousands of years. Rewind is developing the science, certification, licensing policy, and MRV technology, to allow existing supply chains to transport and lock away gigaton-scale carbon within this decade.

Projects

DMS GeorgiaThe project achieves carbon removal by storing biomass in sealed, underground chambers of a coal mine, preventing decomposition and long-term CO₂ release. Sawmill residues (sawdust) are collected, transported, and securely deposited underground. These chambers provide a stable, oxygen-limited environment that ensures permanent carbon sequestration. By repurposing abandoned coal infrastructure for carbon storage, the project effectively offsets emissions while preventing biomass decomposition products from re-entering the carbon cycle.
