Sustainable Biodiesel
Many biodiesel foes rail about the food vs. fuel. Biodiesel can and is being made sustainably. Many focus on biodiesel made from soy and canola oil. They fail to understand that the crops are grown as animal feed so people can enjoy their steaks and pork chops. The oil is a byproduct of this primary purpose of the crop.
Feedstocks that avoid this controversy completely are waste vegetable oil/tallow, biomass and algae.
