Biodiesel is fuel made from renewable resources such as vegetable oils or animal fats. It is biodegradable and non-toxic, and has significantly fewer emissions than petroleum-based diesel when burned.
Biodiesel functions in current engines, and is a possible candidate to replace fossil fuels as the world’s primary transport energy source.
Biodiesel is better for the environment, and it is a lot cheaper to produce biodiesel at home than to buy fuel at a gas station.
