Kiln-Based Technology

Custom-designed and patented technology
“Biochar Now uses custom-designed, patented, slow-pyrolysis kilns to make its biochar.”


Biochar Now uses custom-designed, patented, slow-pyrolysis kilns to make its biochar. The kiln’s unique multi-zone combustion, airflow, negative pressure and recipe-driven control system allow each kiln to independently produce consistent, high quality biochar.

Beetle-kill and fire-damaged trees or other woody materials are shredded and loaded into the kilns as feedstock.

After the conversion is complete, the kiln is picked up by a wheel loader with a custom gripper and transported to the crushing-screening-bagging workstation. After it’s emptied, it moves to the filling station for a new load of shredded wood before returning to the firing line.

The patented, removable stack assembly was designed to chemically convert smoke and other undesirable emissions into clean air permitted by various state agencies across the United States.

Because Biochar Now’s technology is portable, the company designed the rest of the site with removable utilities and temporary buildings so the entire site can be relocated as needed.
