Our Process

We start by sourcing waste biomass - trees and wood that would otherwise be immediately burned, releasing tons of CO2 into the atmosphere. Often, this biomass has been cleared for other projects, or it has been cleared for fire prevention in wooded areas.

Pits are dug, generally at dimensions of 300 X 300 X 12 1/2 feet deep. These pits will be tightly packed with the waste biomass and then covered with impermeable clays native to the area. We never use plastics to line or cover our pits.

This bird’s eye view shows a pit filled with biomass, ready for the clay to go on top, creating a vault that keeps oxygen and water out, and prevents the biomass from going into an aerobic phase (the first step in decomposition).

The pits are covered with clay and compacted to help the soil penetrate the vault and hold the biomass securely. After a few rains, we go back over the pit with our compactor to ensure the pit has enough clay and that any water left in the biomass or in the clays are pressed out.
