Carbon Removal for Wildfire Recovery

North America’s leading post-fire reforestation and carbon removal company.

What we do

Clear the waste timber

left behind by wildfires and thinning

Bury what has no market

instead of letting it burn

Replant the area

funded by carbon removal

We’re optimistic with tools such as burial to deal with burn trees or debris could improve the health of a forest and reduce fire.
—Brian Vrablick, American Forest Management

Proven

Durable removal delivered in months

At Mast’s first MT site, fire-killed trees—biomass that would typically be piled, burned, or left to decay—are now stored underground.

It comes down to risk. The shorter cycle time reduces the risk of project delivery. It's as simple as that. These projects aren't that complicated. The kicker was that you then take money and you go replant trees. I love it for that reason.”
