What is biochar? Biochar is the solid product of pyrolysis, which occurs when biomass is brought to high temperatures with limited oxygen. Biochar’s properties present opportunities for improving soil health, removing contaminants and recovering nutrients as well as providing a mechanism for carbon capture.
Biochar Properties
• Biochar is extremely porous; it has a deceptively high surface area, making it a powerful adsorbing matrix with many potential applications.
• Biochar has a very high adsorption capacity, capturing contaminants and volatile compounds brought into contact with it.
• Many heavy metals, minerals and other non-volatile components in biosolids are retained as solids and immobilized within the biochar structure.
