Bone char is a very effective water filter that removes many heavy metals, chlorine, fluoride and other contaminants from water. It is also used in sugar refining and as a black pigment. It is mostly made from cow bones. The production process is similar to biochar but it contains only 10% carbon. It often has a very high phosphate content of 80%.
Uses in Agriculture
Bone char may also be an intermediate step of processing bones for agriculture. Thick bones such as skulls are very difficult to compost. By charring them first and then putting them through a crusher, the material is much easier to compost. The video below shows how bone char could have an important role in local food systems.
