If you love the smell of French fries, then biodiesel is the fuel for you.
Biodiesel is a liquid, renewable fuel that can be made from a variety of sources, such as vegetable oils, animal fats and even recycled restaurant grease. Chemically-similar to petroleum diesel, biodiesel can be used in nearly any diesel engine and is typically blended with regular diesel fuel. But biodiesel burns much more cleanly, making a direct impact on reducing greenhouse gas emissions. At least five producers of biodiesel operate in Washington State, including the second-largest plant in the nation, located in Grays Harbor.
