What if you could counter global warming by pulling carbon dioxide from the atmosphere without the use of oxygen and then return carbon concentration in the residue to soil as a carbon sink? Sound too good to be true? It actually isn't thanks to biochar.

Biochar is created by partially burning  trees, grass or crop residues without using oxygen and then using the resulting residue in soil to act as a carbon sink. Energy can then be created by converting the exhaust gases from this process. Scientists believe this could actually offset approximately 10 per cent of fuel emissions in the U.S..

It may sound a little confusing, but if you do better with a visual example, watch the video below to see a demonstration of the biochar process.
