Everybody is now aware of the air pollution caused by regular fuels such as petroleum, diesel or gasoline and their long-term effects on the environment. If not for the sake of the Earth, at least for our own benefits, it is far better to switch to biodiesel cars as this fuel is non-toxic and has significantly low amount of exhaust emission compared to regular diesels.

However, one hazard that we constantly face with biodiesel is that, it is not available at all gas stations. Especially if you live in a city, it becomes quite difficult to find a gas station that sells biodiesel. With time, this situation is changing. Still, you never know, with the increase in the price of the edible vegetable oil, when the price of biodiesel also shots up and buying biodiesel may become costlier than regular diesel.

With this in mind, you can follow the examples of the energetic farmers in the countryside who have started making their biodiesel by themselves. This will not only give you an unending supply of fuel as long as soybeans are cultivated on Earth, but will also make your diesel engine perform way better.

Buying or setting up one portable biodiesel processor can solve all your fuel problems once and for all. The benefits of a portable biodiesel processor are that it is easy to build and occupies very less space. It can fit into the corner of your garage or your backyard. The ingredients you will need to make biodiesel in a portable biodiesel processor or a single-tank processor are: vegetable oil, methanol or ethanol and caustic soda (lye). You can use either fresh or cooked/used vegetable oil.

Note that, in order to make biodiesel, you simply need to mix fresh or used vegetable oil with a mixture of alcohol (methanol or ethanol) and a catalyst (lye). You can make it by hand without building a processor. However, this is going to be time consuming. In order to make a portable biodiesel processor you will basically need to fashion a large blender.

The ratio of the oil and alcohol-lye mixture should be around 80:20. Also, it is best to set the whole unit on a wooden platform fitted with wheels so that it is easier to move from one place to the other. There are lots of articles on the Internet with step-by-step instructions to make a portable biodiesel processor at home.
