What is Biodiesel
Biodiesel is a replacement for regular diesel fuel in diesel engines and home heating oil furnaces. Biodiesel is produced from virgin and recycled vegetable oils, such as sunflower oil, or animal fats.
In the U.S., most biodiesel is made from soybean oil, whereas Europe mostly uses canola oil to make biodiesel. Biodiesel is created by a chemical process called tranesterfication, a process in which the vegetable oil reacts with alcohol in the presence of a catalyst. The process results in biodiesel (methl esters) and glycerin (a substance used in soaps and other products).
Biodiesel used for transportation is usually blended with petroleum diesel, commonly as a 20% mix called B20. For home heating systems, the blend is usually B5.
To insure safety and quality, biodiesel should be manuafacutred in accordance with national and international standards, currently a D6751 ASTM standard. Consumers should purchase only fuels that meet the ASTM standard.
