The method used for producing ethanol is different than the method used for producing a biodiesel. What they share in common is the first step for both is to grow the plant that will eventually be used to make the fuel.

For ethanol, once the plant (corn or sugar cane for instance) have been harvested, bacteria are allowed to digest it. When they do this under special conditions where oxygen levels are kept low, it is called fermentation. Fermentation produces ethanol.

For biodiesel, the process requires chemical reactions. There are several different chemical reactions that can be used to produce a biodiesel, the most common of which is called transesterification. This is just a fancy word to describe the process of breaking down fats in the presence of methanol (another type of alcohol).

A biofuel is a fuel that is produced through contemporary biological processes, such as agriculture and anaerobic digestion, rather than a fuel produced by geological processes such as those involved in the formation of fossil fuels, such as coal and petroleum, from prehistoric biological matter.

Biofuels can be derived directly from plants, or indirectly from agricultural, commercial, domestic, and/or industrial wastes.[1] Renewable biofuels generally involve contemporary carbon fixation, such as those that occur in plants or microalgae through the process of photosynthesis. Other renewable biofuels are made through the use or conversion of biomass (referring to recently living organisms, most often referring to plants or plant-derived materials). This biomass can be converted to convenient energy-containing substances in three different ways: thermal conversion, chemical conversion, and biochemical conversion. This biomass conversion can result in fuel in solid, liquid, or gas form. This new biomass can also be used directly for biofuels.
