Biodiesel is an alternative fuel formulated exclusively for diesel engines; it’s made from vegetable oil, animal fats or recycled restaurant grease. Biodiesel can be mixed at any percentage with petroleum and is represented by a number following a B. For example, B5 is 5 percent biodiesel with 95 percent petroleum. B100 is pure biodiesel that has not been blended with gasoline. Biodiesel that meets certain standards can be registered with the U.S. Environmental Protection Agency as a legal motor fuel. Biodiesel reduces emissions of carbon monoxide, carbon dioxide, sulfur dioxide and particulate matter.
In Montana, biodiesel production facilities that produce biodiesel from waste cooking oil and that produce more than 2,500 gallons of biodiesel per year must obtain a Class II Solid Waste Management Systems License. The license must be renewed annually.
Biodiesel production facilities that produce biodiesel from waste cooking oil and who produce less than 2,500-gallons per year for personal use must obtain a Small Biodiesel Production Facility license. The license is free, but requires an annual license renewal.
