Diesel fuel derived from renewable lipid feedstocks, such as vegetable oils and animal fats.
Biodiesel consists of mono-alkyl esters of fatty acids, which are typically methyl esters and are sometimes referred to as fatty acid methyl esters (FAME). These mono-alkyl esters are produced today from fat, grease, or vegetable oil feedstocks using a chemical reaction called transesterification.
Biodiesel blends up to B20 (20%) can be used in most engines and vehicles with no modification.
The handling and storage of biodiesel is an issue compared to classical diesel fuel:
- Different chemical behaviour.
- Degradation of biodiesel.
- Different types of biodiesel that are available around the world.
- Biodiesel The national trade association representing the biodiesel industry in the United States.
