What it is

Biochar is a soil catalyst that can propel rural Africa into the bio-based industrial age. Nature makes biomass from CO₂ through photosynthesis and carbonization. Biomass from agricultural waste is charred by applying high heat in the absence of oxygen. The resulting charcoal, or (bio)char is an important bio-based product which can be used in many different ways. When biochar is buried, it enriches the soil, improving crop yields. Biochar does not oxidize or disintegrate and retains its quality for hundreds of years when buried. With every ton of biochar buried, 3.8 equivalent tons of CO₂ are taken out of the air. Biochar is unique in its capacity to remove CO₂ from the atmosphere.
