Biodiesel Manufacturing
What biodiesel is
Biodiesel is a fuel made from fats and oils, including used cooking oil. A plant makes it by transesterification, which separates glycerin from the fat. Renewable diesel is a different fuel. It is made by treating fats and oils with hydrogen, and it is not biodiesel.
What the plant buys
A biodiesel plant can start from yellow grease, which is collected used cooking oil from fryers. Plants also buy animal fats such as tallow and lard. Those are rendering products. They are not the same material as fryer oil.
What GREASE.ORG does
GREASE.ORG collects used cooking oil from kitchens and sells that oil as a feedstock. GREASE.ORG does not run a biodiesel plant and does not operate a factory shift. The kitchen’s share is the container: fryer oil in, water and food scraps out, and drain grease left in the trap.
