The idea of making biodiesel, a type of fuel that can be less expensive and environmentally damaging than conventional diesel fuel, might gain popularity as gas prices increase. There are a number of ingredients that can be combined to make biofuel, many of which are easy and relatively inexpensive to obtain. In some cases, the process can include the use of potentially hazardous or toxic substances, so it's a good idea for one to exercise caution when making biodiesel. Those who want to make large quantities of biodiesel on a regular basis should consider purchasing a biodiesel kit, which can simplify the process. Numerous books, magazines and websites are available that can provide detailed information about the economic and environmental benefits of making biodiesel.

People might choose to make biofuel for a number of reasons. Perhaps the most obvious is cost, because it usually is cheaper to make fuel than to buy it from a gas station. Others might have ideological reasons, such as reducing dependence on fossil fuels because of the damage they can cause to the environment. Another economic and environmental benefit of using biodiesel could be that it allows materials that normally would be thrown away, such as used cooking oil, to be reused.


Biodiesel can be made from a variety of ingredients. One of the most popular is cooking oil, which some people say can run a diesel engine by itself without any additional processing or ingredients, although special precautions might be required to avoid engine damage. Another process involves mixing lye, methanol or ethanol with used cooking oil. This method also produces glycerin as a byproduct, which can be used to make a household cleaner or hand soap. Some methods for making biodiesel might include the use of potentially hazardous or toxic substances that could require special care and caution.

Kits or processors for making biodiesel can make it easier and faster to produce larger quantities on a regular basis. They can be purchased online for a little as $300 US Dollars (USD) or less. Models with very large capacities and extra features might cost more than $6,000 USD. It also is possible to make a biodiesel processor from household items such as a gas can, funnels, tubing and storage containers.

There is a wealth of information available on making biodiesel. Books, magazines and websites are devoted to various aspects of the subject. Some of the most popular topics include how-to guides for making kits, biofuel recipes and ways to obtain and store the ingredients. Instructions are even available for making a backyard power plant using biodiesel to generate electricity.
