Bone char is primarily made from cattle and pig bones; however, to prevent the spread of Creutzfeldt–Jakob disease, the skull and spine are no longer used. [2] The bones are heated in a sealed vessel at up to 700 °C (1,292 °F); the oxygen concentration must be kept low while doing this, as it affects the quality of the product, particularly its adsorption capacity.
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, often by forming a charcoal kiln , the heat is supplied by burning part of the ...
The word "biochar" is a late 20th century English neologism derived from the Greek word βίος, bios, "life" and "char" (charcoal produced by carbonization of biomass). [8] It is recognized as charcoal that participates in biological processes found in soil, aquatic habitats and in animal digestive systems. [citation needed]

An example of fusain, charcoal that has been fossilized, found at a spoil pile from an underground coal mine in Grundy County, Illinois, US. Fusain is a fossilised carbon deposit which, after some controversy, has been identified as fossilised charcoal. [1] It is fibrous, black and opaque, and often preserves details of cell wall architecture.
Human feces can in principle also be dried and used as a fuel source if they are collected in a type of dry toilet, for example an incinerating toilet.Since 2011, the Bill & Melinda Gates Foundation is supporting the development of such toilets as part of their "Reinvent the Toilet Challenge" to promote safer, more effective ways to treat human excreta.

Charcoal and Activated charcoal vary significantly in terms of composition, manufacturing process, applications, and effectiveness. Charcoal mostly consists of carbon, ash, water, and gasses. Activated charcoal, on the other hand, is primarily carbon but gets an extra activation process. It results in a higher surface area and porous structure.
