Carbon Sequestration

Biochar has been identified as a key means of sequestering (removing and storing) carbon dioxide from the atmosphere into the Earth's soil. A group of scientists published in Nature in 2019 identified Biochar as the negative emissions technology "at the highest technology readiness level."[1] According to their research, the global carbon sequestration potential of biochar (when also using potassium as a low-concentration additive) is over 2.6 billion tons of CO2/year.[1]

Soil Amendment

As a soil amendment, Biochar is the simplest way to increase long-term soil organic carbon content in a form which can endure for thousands of years, as seen in the Amazonian Black Earth.

Additional benefits of Biochar for soil include improved soil texture, nutrient retention, cation exchange capacity,[2] water retention,[3] and microorganism habitat.[4]

Water Filter

Charcoal has been a part of water treatment for at least 4000 years.[1] Biochar’s incredible porosity and surface area give it a high capacity to adsorb a wide variety of contaminants from water.[2]

Laboratory testing shows that biochar can effectively reduce contaminants including:

• Heavy metals like lead, copper, zinc, cadmium, cobalt, and nickel;

• Organics such as gasoline compounds and other volatile organics, polychlorinated biphenyls (PCB), polyaromatic hydrocarbons (PAH), and some herbicides, pesticides and pharmaceuticals;

• Chemical oxygen demand (COD) and biological oxygen demand (BOD);

• Nutrients such as phosphorus and ammonia;

• Totals suspended solids (TSS).[3]

A 2019 study in the Journal of Environmental Management Found that wastewater treatment using biochar in modified sand filters would be able to achieve a similar level of effectiveness in "significant microbe removal" and "reduce the land requirement for implementation of biochar in treatment facilities," overcoming a "major constraint" to wastewater treatment on farms.[4]
