Alcohols, esters, ethers, and other chemicals (biodiesel, ethanol, and methane) made from cellulosic biomass sources or organic matter (herbaceous and woody plants, animal fats, agricultural and forest waste, or municipal solid and industrial waste) within an active carbon cycle. Production and combustion of biofuels take and replenish the CO² in a circular, sustainable fashion. These fuels are used for stationary and mobile applications, i.e., electricity and transportation. Two commonly used biofuels are ethanol and biodiesel.
A gaseous, liquid or solid fuel derived from a biological source, e.g. ethanol, rapeseed oil or fish liver oil.
The joint name of fuels which originate from plants (biomass). This can include everything from wood and straw to refined biofuels such as pellets and ethanol. Biofuels are converted solar energy; plants transform solar energy into chemical energy in the form of different types of sugar. Biofuels are renewable because they can be re-created in a relatively short period of time once they have been used, as long as we do not consume more than we grow. Cutting down too many trees can have a negative effect on biodiversity. Peat is no longer regarded as a biofuel.
Usually meaning an overall term for vehicles powered by bioethanol.
A renewable energy source. There are two main types of biofuel: bioethanol and biodiesel.
any fuel made from nonfossil organic matter, such as vegetable oil or ethanol.
Fermentation occurs when anaerobic digestion converts sugars into ethanol with the use of micro-organisms, usually yeast. Bioethanol can be used as a transport fuel by mixing it with petrol or using it directly in a modified combustion engine. Sugar cane or beet is the most efficient source but potatoes, corn, wheat and barley can also be used. Processes that produce bioethanol from woody material, such as forestry residues, energy crops and waste paper, are also approaching commercial viability and a number of pilot plants are proposed for the UK. Biodiesel can be made from vegetable oils, animal fats or recycled cooking oils. However, the production of biodiesel requires a high amount of energy, offsetting its ability to reduce carbon emissions. However, it still provides an improvement over fossil fuels, typically reducing lifecycle carbon dioxide emissions by over 60 per cent (source: British Biogen).
A gaseous liquid or solid fuel that is rendered from raw biological material (plants, sewage, dry waste, cane sugar or wood pulp) through combustion or fermentation.
Electrical power derived from biomass, such as cow manure.
Gas, such as methane, or liquid fuel, such as ethanol (ethyl alcohol) made from organic waste material, usually by microbial action.
gas or liquid fuel made from plant material (biomass). Includes wood, wood waste, wood liquors, peat, railroad ties, wood sludge, spent sulfite liquors, agricultural waste, straw, tires, fish oils, tall oil, sludge waste, waste alcohol, municipal solid waste, landfill gases, other waste, and ethanol blended into motor gasoline.
Fuel derived from biomass i.e., a substance produced by living organisms but not fossil fuels, for example, wood from energy forests and timber waste.
Biofuels are renewable liquid fuels made from plant matter rather than fossil fuels. Today’s primary biofuels are ethanol and biodiesel. Biofuels can help reduce air toxics emissions, greenhouse gas buildup, and dependence on imported oil, while supporting United States agriculture.
A fuel produced from dry organic matter or combustible oils produced by plants. Examples of biofuel include alcohol (from fermented sugar), bio diesel from vegetable oil and wood.
Fuel that is produced from renewable sources Chain of Custody The process by which the source of a (forest) product is verified
A gaseous, liquid or solid fuel that contains energy derived from a biological source. For example, rapeseed oil or fish liver oil can be used in place of diesel fuel in modified engines. A commercial application is the use of modified rapeseed oil, which - as rapeseed methyl ester (RME) - can be used in modified diesel engines, and is sometimes named bio-diesel. cf biogas.
Fuel derived from organic materials, such as wood.
fuel produced directly or indirectly from biomass
Fuel, which is available directly or indirectly from biomass.
Biofuels are gas or liquid fuel ( alcohols, ethers, esters, and other chemicals) made from plant material, agricultural and forestry residues, and a large portion of municipal solid and industrial waste. Biofuels include material as diverse as wood, wood waste, peat, wood sludge, agricultural waste, stray, sludge waste, municipal solid waste, landfill gasesÉ Biofuels for transportation include bioethanol, biodiesel, biomethanol, and pyrolysis oils.
Fuels devised from biological materials including crops (especially trees) and animal wastes
Renewable fuel such as bark and wood waste.
Gas or liquid fuel (such as ethyl alcohol) made from plant material (biomass).
Fuels made from plant or animal material, e.g. wood, straw and ethanol from plant matter.
Biofuel is any fuel that is derived from biomass — recently living organisms or their metabolic byproducts, such as manure from cows. It is a renewable energy source, unlike other natural resources such as petroleum, coal, and nuclear fuels.
