The definition of biodiesel is a fuel made from vegetable and animal fat oils that have been processed to remove glycerin, sometimes combined with petroleum-based diesel (labeled a biodiesel blend) and for use in most diesel engines without modifications.
An example of biodiesel is fuel made from recycled vegetable oil from restaurant fryers.
A biofuel made by processing vegetable oils and other fats for use in a diesel engine, either in pure form or as an additive to conventional diesel fuel.
- Studies have shown that biodiesel from virgin vegetable oil reduces carbon dioxide emissions and petroleum consumption when used in place of petroleum diesel.
- The United Soybean Board terms it this way: Biodiesel is a mono-alkyl oxygenated fuel made from soybean or other vegetable oils or animal fats.
- This is due to the fact that growing soybeans consumes nearly four times as much CO2 as the amount of CO2 produced from biodiesel exhaust.
- Can be used in a diesel engine with a blend of 20 percent biodiesel and 80 percent petroleum without any modification to the engine.
- Biodiesel blends can also be used in a standard oil fired furnace or boiler, making it an alternative fuel source for heating residential homes.
