Brit.

/ˈbʌɪəʊˌtʃɑː/, U.S.

/ˈbaɪoʊˌtʃɑr/

Origin: Formed within English, by compounding. Etymons: biomass n., charcoal n.

Etymology: < bio- (in biomass n.) + char- (in charcoal n.).

Charcoal produced by the combustion of plant matter in the absence of oxygen, which is mixed into soil as a conditioner and to remove carbon dioxide from the atmosphere that would otherwise contribute to global warming.In quot. 1995: charcoal of this type used as fuel.

1995 R. M. Hummelshøj in Proc. 8th European Biomass Conf. 1994 III. 1843 In pelleted form the produced biochar is a very energy dense bio-fuel.

2006 Geogr. Rev. 96 485 Less deforestation from shifting cultivation and the sequestration of bio-char into cultivated soils could reduce carbon dioxide emissions.

2007 New Scientist 20 Oct. 31/3 What could make the whole process ‘carbon negative’ is what's left at the bottom of the kiln, a charcoal high in organic carbon that IBI has dubbed biochar, which could be used to improve the quality of soil. Because the carbon in biochar takes hundreds to thousands of years to decompose and enter the atmosphere, it acts like a carbon sink.

2016 P. Wadhams Farewell to Ice (2017) xiii. 186 On land, other techniques include those to increase the amount of carbon sequestered in the soil, for example by ploughing in organic material such as straw, reducing ploughing (to limit soil disturbance) or adding biochar.
