Biodiesel and Renewable Diesel Definitions

Biodiesel is defined as a fuel that is comprised of mono-alkyl esters of long chain fatty acids derived from vegetable oil or animal fats and that meets ASTM D6751. Renewable diesel is defined as a fuel produced from non-fossil renewable resources, including agricultural or silvicultural plants, animal fats, residue, and waste generated from the production, processing, and marketing of agricultural products, silvicultural products, and other renewable resources. Renewable diesel must meet applicable ASTM specifications. (Reference North Dakota Century Code 57-43.2-01)
