How is
Biodiesel Made?
Biodiesel is made through a controlled chemical reaction called
transesterification. Feedstocks such as virgin oils (soy, palm,
etc.), rendered animal fats (chicken, tallow, etc.), or waste
vegetable oils (WVO) are heated and combined with methanol and a
catalyst.
The result of this chemical reaction is the production of pure
biodiesel (B100) with glycerin as a resulting byproduct. Methanol is
recovered and reused in the process. Glycerin has a wide range of
uses from animal feed additives to pharmaceutical applications.
Finished biodiesel that meets ASTM D6751 standards is then
distributed and consumed through America's existing fueling
infrastructure, whether used as pure biodiesel or in any blended
mixture (B20, etc.).
