Biodiesel is a clean-burning diesel alternative made from any natural
oil or fat. It can be made easily in a backyard or garage environment.
In this class, you will learn how to make your own clean burning diesel
fuel alternative and how to build the processing equipment to make it at
This is a comprehensive, hands-on workshop on making homebrew biodiesel
fuel out of waste restaurant fryer oil, which can usually be acquired
for 'free'. We'll be looking at a working biodiesel homebrewing system
and will make a small batch in that system.
Most of the class focuses on the chemistry behind biodiesel homebrewing
and quality control, and we'll be doing a lot of 'lab' work making test
batches, and variations on different formulas.
The feel of the class is a bit like the mad scientist version of "high
school chem lab" (hopefully without the spitballs and giggling)- you'll
be doing hands-on lab exercises in small groups, which will teach you
how to make and troubleshoot your home batches- and we'll be learning
the chemistry basics that underlie making good quality fuel for your
This is a fast-paced class, and I strongly recommend that you read this

to get a background for
The class will also cover equipment and system construction. We will
discuss heat exchangers, solar thermal heating of the process, some
minimal methanol recovery information, and other equipment topics.
There is a working, functional homebrewing system on a trailer that we
will tour during the class.
This class teaches you everything you need to know to make high quality
biodiesel, use your system more efficiently, and make informed decisions
about shortcuts. We cover the following topics, but also tailor the
class to more advanced students or different questions, as appropriate.
There are extensive hands-on lab portions in the class during which you
will get individual attention to make sure you understand the topics
fully and can do the techniques on your own at home.
biodiesel/SVO/solvent thinning (ie DSE etc) options and history
testing oil (titration and water testing)
making test batches
an overview of equipment
a chance to build your own reactor at the end of Sunday's class
quality control factors, quality testing
mistwashing and other water washing options

hands-on experience recovering from failed batches and emulsion
To register for the class:
There is plenty of space in our large classroom, so pre-registration
isn't necessary at this point. The class runs from 10-4 each day
Saturday and Sunday. Wear 'work clothes' in case you spill oil on
yourself. We will have safety gear for you. If desired, you may bring a
sample (1 gallon max!) of oil that you'd like to test out, or a sample
of any biodiesel you may have made.
