biofueln.

Brit.

/ˈbʌɪə(ʊ)ˌfjuːəl/, U.S.

/ˈbaɪoʊˌfju(ə)l/

Origin: Formed within English, by compounding. Etymons: bio- comb. form, fuel n.

Etymology: < bio- comb. form + fuel n. With sense 2 compare earlier biogas n.

1. Organic matter or (typically) a living organism or biologically active enzyme used as a means of generating energy in a fuel cell. Usually attributive.

ΚΠ

1963 Proc. IEEE 51 812/1 The action of Desulfovibrio bacteria has been observed in a prototype biochemical fuel cell... Best results to date have been obtained with fresh mushroom as the bio-fuel.

1964 Biochimica et Biophysica Acta 88 376 Bio-fuel cells utilizing enzymes at the anode and O₂ at the cathode have relatively low output.

2000 New Scientist 22 Apr. 10/1 They have built a 0.6 volt biofuel cell that can deliver currents of up to 17 milliamperes.

2007 Guardian 26 Apr. (Technology section) 6/7 Professor Derek Lovley, at the University of Massachusetts, has a microbial biofuel cell which he's also used to power a calculator.

2. Fuel consisting of or manufactured from organic matter of recent origin, such as plant material, animal waste, or municipal or industrial waste, and typically used as a substitute for fossil fuels. Cf. biodiesel n., bioethanol n.In contrast to fossil fuels (which are obtained from long-dead organic matter), biofuels are regarded as renewable. However there is debate about the effect of destroying habitats in order to plant biofuel crops.

1974 Energy Primer 106/2 Because wood is such an exploitable biofuel, we felt that reasonable space ought to be devoted to a discussion of its efficient use.

1985 Fortune 13 May 82/2 The use of biofuels in place of expensive oil naturally means big savings in energy costs.

1992 Farmers Weekly 14 Aug. 40/1 Within five years 600,000t of the new rape-based bio-fuel rape methyl ester (RME) will be produced on the Continent.

2008 Ecologist July–Aug. 32/2 The big problem with using biofuels at altitude—both biodiesel and ethanol—is that they clump together and freeze at much higher temperatures than kerosene.
