Biochar is made through a process called pyrolysis where biomass is “baked” with little oxygen under controlled temperatures and pressures. This releases a highly useful volatile gas and leaves a charred material that is 60 to 90% carbon.
A small fraction of the gas (syngas) is used to perpetuate the production process and the remainder can be used to generate carbon neutral electricity, heat for adjacent buildings, hydrogen gas, and bio-crude oils and fuels.
At AirTerra we see three key reasons why Biochar is vitally important.
Since biochar can sequester carbon in the soil for hundreds to thousands of years, it has received considerable interest as a potential tool to slow global warming. The burning and natural decomposition of trees and agricultural matter contributes a large amount of CO2 released to the atmosphere.
