Mast Reforestation announced the completion of biomass burial at its Mast Wood Preserve MT1 project in Montana. Just four months after starting, Mast has filled, capped, and begun monitoring for greenhouse gases. This is part of their MRV process—monitoring, reporting, and verification.
This project is the first to combine engineered carbon removal through burned biomass burial with post-wildfire reforestation.
Mast has become a leader in Terrestrial Storage of Biomass (TSB). Biomass burial captures carbon in fire-killed logs. It is one of the most efficient biomass-based carbon dioxide removal (CDR) pathways available today.
This project proves that advanced and durable CDR solutions can scale quickly and cost-effectively. Biomass burial is similar to biochar. However, it sequesters up to twice as much carbon from the same source.
The credits are verified through detailed wood analysis, weight records, and MRV. So far, MRV results show no greenhouse gases are escaping from the chamber. Long-term monitoring is funded by an independent endowment. It exceeds industry standards to ensure durability.
Over 10 million pounds of fire-killed trees have been buried. These trees were headed for pile burning to clear land. Instead, they are now stored safely underground. This keeps the carbon out of the atmosphere for at least a century.
The buried trees also fund reforestation efforts on the same land; this helps ecological recovery and preserves biodiversity. The area is home to threatened species and cultural sites. Revenue from the project supports land stewardship, forest growth, and silvopasture.
MT1 shows a way to accelerate reforestation after large-scale wildfires. It supports local livelihoods and ecological recovery. The project can generate and retire credits within a year. Mast plans to expand biomass burial projects across Montana.
