This innovative biochar kiln design allows for the production of high quality biochar while incorporating a condensation chamber for the simultaneous production of wood vinegar. While the biochar can be used for a high quality soil amendment, wood vinegar is used as an effective organic pesticide... all derived from waste organic matter!
