What is exactly biodiesel?

Question

Can someone eactley explain to me in plain english what is biodiesel please!

Answer 1

Taken fromthe website below: "Biodiesel is a fuel made from vegetable oil that runs in any unmodified diesel engine. Biodiesel can be made from any vegetable oil including oils pressed straight from the seed (virgin oils) such as soy, sunflower, canola, coconut and hemp. Biodiesel can also be made from recycled cooking oils from fast food restaurants. Even animal fats like beef tallow and fish oil can be used to make biodiesel fuel. While biodiesel may sound like something from the movie “Back to the Future,” its use dates back over 100 years to the invention of the diesel engine."

Answer 2

Biodiesel refers to a diesel-equivalent processed fuel derived from biological sources (such as vegetable oils) which can be used in unmodified diesel-engine vehicles. It is thus distinguished from the straight vegetable oils (SVO) or waste vegetable oils (WVO) used as fuels in some diesel vehicles.

In this article's context, biodiesel refers to alkyl esters made from the transesterification of vegetable oils or animal fats.
