With the crazy fluctuation in gas prices, especially here in San Francisco, you can cut down on additional carbon footprint through biodiesel and here’s how to make your own biodiesel at home!

This is my tutorial for using my appleseed processor to make biodiesel. This tutorial will get you through the process of making biodiesel, but not the necessary washing process. I will do my next instructable on dry-washing biodiesel.

Biodiesel is a great way to go green, and cut your carbon footprint quite substantially, not to mention it’s cheaper than diesel. Biodiesel will run in a diesel engine, I don’t recommend trying it in a gas engine.
The process for making biodiesel uses an oil, a catalyst, and an alcohol. In this case: Waste vegi oil (WVO), NaOH (lye), and methanol.

Please read up on this before you start, and please understand the chemical dangers involved in this process.
