Biochar vs. Charcoal — What's the Difference?

Biochar is charcoal that is produced by pyrolysis of biomass in the absence of oxygen; it is used as a soil ameliorant for both carbon sequestration and soil health benefits. Biochar is a stable solid that is rich in carbon and can endure in soil for thousands of years.

A porous black solid, consisting of an amorphous form of carbon, obtained as a residue when wood, bone, or other organic matter is heated in the absence of air.

Charcoal that is used as a soil conditioner.

Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, the heat is supplied by burning part of the starting material itself, with a limited supply of oxygen.

A black, porous, carbonaceous material, 85 to 98 percent carbon, produced by the destructive distillation of wood and used as a fuel, filter, and adsorbent.

A dark grayish brown to black or dark purplish gray.

To draw, write, or blacken with a black, carbonaceous material.

To charbroil.

Impure carbon obtained by destructive distillation of wood or other organic matter, that is, heating it in the absence of oxygen. Category:en:Carbon

To draw with charcoal.

To cook over charcoal.

Impure carbon prepared from vegetable or animal substances; esp., coal made by charring wood in a kiln, retort, etc., from which air is excluded. It is used for fuel and in various mechanical, artistic, and chemical processes.
