Basic Principles of Biochar Production - Biochar for

Biomass: living or once-living material, which is the feedstock (starting material) for making biochar. Nearly all organic materials, such as bark, nutshells, crop residues, and manurescan be used as feedstock in appropriate devices. Charcoal: the solid, carbon-rich residue left when biomass is heated in an environment with limited oxygen. Generally, charcoal is made from wood, and is intended
