Biodiesel & Green Diesel

Biodiesel is a biofuel that is similar to traditional or "fossil" diesel. Biodiesel is a type of diesel fuel made from long-chain fatty acid esters obtained from plants or animals. Transesterification is the process of converting these oils into Biodiesel. Transesterification is a chemical reaction that produces a methyl, ethyl, or propyl ester by combining lipids such as animal fat (tallow), soybean oil, or another vegetable oil with an alcohol. As a green energy, biodiesel could be a viable replacement for fossil fuels. It can help to prevent air pollution by lowering CO_2, SO₂, CO, and HC emissions.

Green diesel is a second-generation biofuel with a similar molecular structure to petroleum diesel but improved diesel characteristics. It is one of the alternative energy products. Green diesel is now made from a variety of biomass sources, including animal and fish fats, although the term HVO is still used in the industry, as well as in fuel standards and European regulation. Green diesel is made up of a mix of straight chain and branched saturated hydrocarbons with 15 to 18 carbon atoms per molecule (C15 to C18).
