What is biochar

So what is this biochar? It is a type of charcoal produced from organic waste, such as wood, roots, grasses, coconut husks, bones, and manure. The production is done in the process of pyrolysis, which is burning the matter with no or low oxygen. Without access to oxygen, carbon stored in the matter does not convert to CO2, hence it stays in the final product – biochar. When it is deposited in the soil, it can reduce the amount of CO2 we have in the atmosphere.

Biochar is discussed as a solution to implement on the global scale to capture excess carbon from the atmosphere and safely deposit it in soils. It is argued that biochar can hold carbon much longer, even 1000 years! Moreover, it improves soil fertility, which is an added benefit. Some studies show that soil fertility with biochar in a deeper layer can be as much as 800 higher! Regular soil holds less than 1% of carbon, whereas soils with biochar have this percentage reaching 10%!
