The term ‘biochar’ refers to black carbon formed by heating biomass (plant wastes, feedstocks, etc.) in an oxygen-free or low oxygen environment so it does not combust. The technical term for this process is pyrolysis. Traditional charcoal is one example of biochar produced from wood. However, the term ‘biochar’ is much broader than this, encompassing black carbon produced from any biomass feedstock.
