Anandvan Trivia Quiz

Question 1: Why am I known as “Biofuel crop”?
Answer: Biodiesel is a clean and renewable fuel which is considered to be the best substitution for diesel fuel. When burned, pure biofuels generally produce fewer emissions of particulates, sulfur dioxide, and air toxics than their fossil-fuel derived counterparts. Inedible oil producing plants can be used as biofuel crops so that there is no conflict between food and fuel. Such oil is also much cheaper than edible oil.
