What types of oil can be used to make Biodiesel?
Biodiesel can be made from ALL types of vegetable and animal oil, but oil that is from animal sources (tallow, lard, grease, etc.) needs special conditions and procedures to process it successfully. All vegetable oils can be used, including all seed oils, nut oils (including peanut oil), bean oils (including soybean oil), olive oils, and oil pressed from algae. Biodiesel can be made from new or used oil. Before processing USED oil into Biodiesel, it is necessary to test the oil to see how much lye is needed for that particular batch of oil. The amount of lye needed will vary from one batch of oil to another, so it is extremely important to test each batch of oil first before processing it into Biodiesel. Testing the oil is not a difficult process, but it must be done correctly to give accurate results.
