Biochar starts as biomass – plant matter, old wood, agricultural waste – that is pyrolyzed, or heated to high temperatures without oxygen. The result is a solid chunk of carbon that no longer releases CO₂ back into the atmosphere. Biochar is an example of a CDR method that comes with an end product that can be used for many things including as a soil amendment, to build roads, water filtration, and so much more. Our biochar removals are supplied by CarboCulture.
