Reclaim Mines.
Remove Carbon.
Rewind delivers permanent, certified carbon removal by sealing sustainably sourced biomass in mine voids. The same process solves mine reclamation, turning the industry's largest environmental liability into a climate solution.
The Opportunity
Every mine must close.
Few turn that into value.
The global mining industry faces over $150 billion in closure and reclamation liabilities. Backfilling voids, treating acid mine drainage, stabilizing subsidence — these are regulatory obligations with no return.
Rewind changes the equation. We backfill mine voids with sustainably sourced biomass, locking carbon for millennia while fulfilling reclamation requirements. What was pure cost becomes a source of certified carbon removal revenue.
How It Works
From forest floor to sealed mine voids.
Source Biomass
Sustainably sourced wood residues, forestry waste, and agricultural byproducts from certified local supply chains. No deforestation. No competition with food or timber markets.
Engineer Backfill
Biomass is processed and formulated into backfill material optimized for the specific mine environment, balancing structural stability, carbon density, and reclamation requirements.
Seal Underground
Backfill is placed into mine voids and sealed, creating oxygen-free conditions that prevent decomposition. Carbon is locked in place permanently while fulfilling mine reclamation obligations.
Monitor
Continuous digital MRV (dMRV) tracks storage integrity, gas composition, and structural stability across the sealed chambers.
Verify & Issue Credits
Monitoring data feeds into third-party verification under Isometric's BSSM protocol, enabling certified carbon removal credit issuance.
Why Rewind
Reclaim your mines.
Reduce your costs.
Permanent removal.
Scalable supply.
Operational Today
The world's first commercial Enhanced Mine Reclamation project.
Rewind operates at the Saknakhshiri coal mine in Tkibuli, Georgia — an active mine where we are storing biomass carbon in sealed mine voids today. The project is certified under Isometric's Biomass Storage in Sealed Mine (BSSM) protocol, with first credit issuance in 2026.
