What is Biofuel?

Biofuel is fuel derived from renewable biological sources such as plants, animals, and waste. Biofuel is a flexible fuel that can be used either in its pure form or blended with petroleum-based diesel fuel. For example, biodiesel, a biofuel end product technically known as mono alkyl esters, is a clean-burning, diesel-equivalent process fuel made from natural, biological sources. Because of their positive environmental impact, biofuels such as biodiesel have been termed “green” oil.
