What is Biodiesel?

July 12, 2016

Biodiesel is an alternative energy source for diesel engines. Commonly made from grease, vegetable oils, or fats, this fuel source can be used on its own (referred to as B100) or in combination with conventional petroleum diesel in 5 percent and 20 percent. According to the EPA, biodiesel can reduce greenhouse gases by between 57 and 86 percent and is considered safer to handle due to its lower toxicity.

Biodiesel is produced through what is called transesterification. Here, the glycerin is separated from the fats and oils. This leaves behind the biodiesel while the separated glycerin is used in the production of soaps and other products.
