If you’re interested in making your own biochar, you can do so using a process called pyrolysis. Here’s a basic outline of how to make biochar at home:

  1. Choose a suitable container: Select a metal drum or airtight container with a lid. The container should be capable of withstanding high temperatures without releasing toxic gases or air pollutants.

  2. Collect organic material: Gather plant-based organic material, such as woody prunings, branches, or crop residues. Avoid using treated wood, painted material, or materials that may contain chemical residues.

  3. Prepare the container: Drill several small holes in the container to allow excess moisture and gases to escape during the pyrolysis process. Ensure that the container is placed in a well-ventilated and open area to prevent the buildup of toxic gases.

  4. Load the container: Fill the container with the organic material, ensuring that it is tightly packed to encourage the production of high-quality biochar. Be cautious not to overload the container, as this could hinder air circulation.

  5. Seal the container: Securely attach the lid to the container to create an airtight seal. This helps create the necessary conditions for pyrolysis by limiting the oxygen supply during the process.

  6. Start the pyrolysis process: Place the sealed container on a fireproof surface, such as a concrete or metal area, away from flammable materials. Ignite the organic material through a small hole in the container, allowing it to catch fire.

  7. Monitor the process: Once ignited, closely monitor the pyrolysis process. The organic material will release volatile gases as it heats up. These gases should be allowed to burn off. Once the flames have subsided, reduce the oxygen supply by closing any air vents on the container. This will encourage the biochar formation.

  8. Cool and store the biochar: After the pyrolysis process is complete, allow the container to cool down completely before opening it. The resulting material is biochar. Store the biochar in a cool, dry place away from moisture and direct sunlight.
