EVC1: Transesterification to biodiesel
EVC1: Transesterification to biodiesel Biodiesel (FAME) is produced from vegetable oils, animal fats, used cooking oils (UCO), greases and other fats and oils. Oils and fats mainly consist of triglycerides, i.e. three long (C 10+ ) and straight fatty acid chain molecules linked to a glycerol ( i.e. propanotriol, glycerine) molecule via ester functionalities.

Biodiesel: A Renewable, Domestic Energy Resource
Since the soybean plant is a legume, a crop of soybeans requires less nitrogen fertilizer than required by some other renewable energy crops. Soybean oil is extracted from soybeans by crushing and pressing the beans to expel the oil. In some cases, a chemical solvent is used to obtain a greater oil yield.

Exploring the Potential for Soybean Biodiesel
How soybean biodiesel stacks up. The production of biodiesel requires less energy and results in lower emissions compared to fossil fuels. When it comes to performance, biofuel is closely on par with petroleum diesel in terms of fuel economy, horsepower, and torque—and it even offers some advantages like enhanced lubrication, which can extend engine life.
