On June 26th, we completed our first BioChar burn with the USFS at Sherman Pass in the Colville National Forest. We were able to burn 1.5 piles of hand-piled slash. Mother Nature intervened and doused our kiln early with a hailstorm, followed by a thunderstorm. Lightning was too close for comfort, with simultaneous flash and bang.

Still, we were able to achieve a good pyrolysis temperature of 600°F. After 3 hours, we finished with approximately 30 cubic feet of biochar that will serve as a soil amendment and sequester almost a quarter ton of atmospheric CO2.
