Biofuel Facts
Two fuels from the same oil
Biofuel, on this page, means fuel made from fats and oils, including used cooking oil. Biodiesel and renewable diesel are the two fuels a kitchen hears about. Biodiesel is made by transesterification. Renewable diesel is made by treating fats and oils with hydrogen. They are not the same fuel. A plant can start either one from used cooking oil.
Why plants buy used cooking oil
Federal and state fuel programs have encouraged biofuel made from crops, vegetable oils, and animal fats. Biomass-based diesel is mostly biodiesel and renewable diesel. When plants add capacity, they look for more animal fats, waste oils, and grease. This page does not quote a gallon total, a jobs figure, or an emissions percentage. The U.S. Department of Agriculture’s Oil Crops Outlook: July 2024 is one public record of that market.
What a kitchen can do
A kitchen does not need a national total to take part. Used cooking oil left in a container can be collected. GREASE.ORG picks up that oil. The oil is a feedstock. GREASE.ORG does not publish a production total on this page.
