Biodiesel

Biodiesel is a diesel fuel made from fats and oils. Used cooking oil and yellow grease are common feedstocks. The fuel is not the same thing as the kitchen oil it came from, and it is not petroleum diesel.

These posts follow biodiesel manufacturing, production and distribution, renewable diesel next to biodiesel, and the feedstock questions that change how the fuel behaves. A fun-facts note and a yellow-grease feedstock note sit here because they are about the fuel, not about a trap pump-out.

GREASE.ORG picks up used cooking oil and pumps grease traps. The articles explain the path from a kitchen load to a fuel, so a reader can tell a feedstock from a finished gallon.
