PART 1: INTRODUCTION
Biodiesel is a renewable fuel derived from a chemical reaction of alcohol and vegetable
or animal oils, fats, or greases. These oils or fats are chemically altered in order to
allow use in any diesel engine or home oil heating system, with little or no modification.
A process called transesterification removes the glycerin component of the oil (which is
a triglyceride molecule), resulting in a much thinner, or less viscous, product which
stays liquid down to much lower temperatures. Biodiesel can be used in any diesel
engine in pure form or blended with petroleum diesel in any percentage. Existing gas
stations, pumps, and tanks can use biodiesel, providing a near seamless integration into
our vast petroleum infrastructure. Even a commonly used blend of 20% biodiesel and
80% petroleum diesel (B20) will significantly reduce harmful pollutants, as well as
carbon dioxide gas, reducing your vehicles contribution to climate change.
One of the most exciting aspects of biodiesel is the fact that it is readily produced from
used restaurant fryer oils. Restaurants must properly dispose of significant quantities of
waste veggie oil (often referred to as grease, or its trade name, yellow grease). The oil
may therefore be easily be acquired for small scale biodiesel production operation.
Using recycled waste fryer oil to produce biodiesel provides the benefits of a U.S.
grown, renewable fuel, as well as offering a low cost option to recycle a waste product
and put it to good use reducing carbon dioxide and other harmful emissions.

BIODIESEL CHEMISTRY
Biodiesel use should not be
confused with the combustion of
straight vegetable oil, or SVO.
SVO may be used directly into a
diesel engine. However, the fuel
supply system must be modified
by the addition of a second fuel
tank, heating systems, and fuel
switching to accommodate SVO
(see Appendix B).
In the case of biodiesel, the engine and fuel systems are not modified, but we instead The glycerin phase is more dense than biodiesel phase and the two can be
