Biochar is the carbon rich remains of organic material that has been heated to decompose and remove most of the hydrogen and oxygen. The process is called pyrolysis and is carried out in the absence of air/oxygen to prevent the material catching fire and burning. The black residue contains the remains of the starting material.
The Biochar process
Biochar is made through a process called pyrolysis, which involves heating organic material in the absence of oxygen. The process typically involves the following steps:
Feedstock preparation: The organic material, or feedstock, is prepared for pyrolysis. This may involve chopping, drying, or grinding the material, depending on its moisture content and size.
Pyrolysis: The prepared feedstock is placed in a pyrolysis reactor, which is then sealed and heated to high temperatures. The absence of oxygen in the reactor prevents combustion and allows the organic material to decompose into a stable and porous carbon-rich substance.
Cooling and collection: After the pyrolysis process is complete, the reactor is cooled and the biochar is collected.
Conditioning: The biochar may be conditioned to remove any residual moisture or volatile organic compounds. This can be done through air-drying, oven-drying, or the use of a vacuum system.
Application: The final product is then ready for use as a soil amendment, a filter for water or air purification, a component in the production of energy, or for other applications.
Overall, the pyrolysis process is a simple and efficient way to produce biochar from a wide range of organic materials. By converting waste materials into a useful and valuable product, biochar production can help to mitigate environmental challenges while providing economic benefits.
There are vast uses for the end material, there are a few listed below.
