Biochar is defined by the International Biochar Initiative as the "solid material obtained from the thermochemical conversion of biomass in an oxygen-limited environment".

Biochar is a charcoal-like product made from biomass waste, such as wood or agricultural waste, paper mill waste, or other biological residues. The concept for use as a soil amendment originated in …

Feb 27, 2024 · Biochar is a type of processed plant matter that is very rich in carbon. Lightweight, black and very porous, it looks and feels very much like charcoal. But where charcoal is used for cooking …

Biochar has several unique chemical and physical properties that make it very useful for retaining nutrients and water. Biochar ranges from 50 to 90 percent carbon and less than 0.1 percent nitrogen. …

Through biochar, biomass becomes a sustainable and value-added product for urban and rural agricultural and forest communities by creating jobs, improving soil, and reducing forest fire hazards.

Biochar is produced through pyrolysis or gasification — processes that heat biomass in the absence (or under reduction) of oxygen. In addition to creating a soil enhancer, sustainable biochar practices can …
