Make Your Own Biodiesel Processor

Categories: DIY

In a world where environmental awareness is becoming increasingly important for individuals, businesses, and mankind as a whole, it's always important to be looking for ways to re-use waste and cut carbon emissions. Biodiesel is a great way to do this. You're reusing waste oil and reducing your impact on the environment.

This Instructable will take you step-by-step through the process of making a BioDiesel processor. This type of Processor is called an appleseed processor. It uses an old (or new if you feel like dropping the money) water heater. The amount of fuel you can make will depend on the size tank you use. My first prototype uses a 10 gallon tank. Not too efficient if you plan on making large quantities, but great for figuring things out.

Before you do this project you should research the process and dangers involved in producing biodiesel at home.

Before you run out and buy $100+ worth of plumbing materials, I should say this: As biodiesel becomes more and more popular the resources available become more and more scarce, and people are starting to charge for things that used to be free, specifically Waste Vegetable Oil (WVO). I would suggest securing a source for WVO before you embark on this project.

There are many unspoken rules about gathering WVO from businesses, and I can talk about those in another instructable. For now just know that you CANNOT just take oil, for this you can get arrested and tried. You also need to be consistent (If you say you'll be there every Tuesday to pick up someone's oil and you show up on Wednesday half the time people will often give your oil to other people).

Step 1: Do some research

Do some research. You can't read too much about biodiesel. I spent about a year researching before I built this and started making fuel.
A book that is a must read is Biodiesel Basics and Beyond: A Comprehensive Guide to Production and Use for the Home and Farm Much of the information you find on the internet (including this instructable, no doubt) is incomplete information. This book will give you the ins and outs of every step you need to take.
Be familiar with how the process works before you build a processor. If you understand how it's supposed to operate when it's finished, you will make fewer mistakes when you're building it.
