Biochar is created by heating organic material under
conditions of limited or no oxygen.
There are many ways to achieve this result. The type of
organic matter (or feedstock) that is used and the conditions
under which a biochar is produced greatly affect
its relative quality as a soil amendment . The most important measures
of biochar quality appear to be high adsorption and cation exchange capacities and low levels of mobile matter
(tars, resins, and other short-lived compounds). Production of biochar generally
releases more energy than it consumes, depending on the
moisture content of the feedstock . Heat,
oil, and gas that are released can be recovered for other
uses, including the production of electricity. A sustainable
model of biochar production primarily uses waste
biomass, such as greenwaste from municipal landscaping,
forestry, or agriculture (for example, bagasse).
