Making Biodiesel at Home – What Exactly is It?

Petroleum prices are rising across the globe. Escalated prices are giving nightmares to common man. Consequently some people are looking towards substitutes. An excellent alternative to fossil fuel in this category is biodiesel. Biodiesel is a clean burning fuel and more importantly, it is a renewable energy source. Environmentally this fuel has proven to be a much less pollutant than its counterpart, the standard diesel. The regular diesel has components such as sulfur and aromatics. This fuel is made out of vegetable oil and costs considerably lesser than the conventional fuel. Because of this property it is easy to make biodiesel at home.

Biodiesel is outcome of the process called transesterification. In this method the fats are removed from the vegetable oil thus leaving behind byproducts like glycerin and biodiesel. In view of the fact that biodiesel does not contain sulphur and aromatics, it burns cleaner leaving very few traces of contaminants. These characteristics make biodiesel surpass the conventional petroleum fuel.

The most fantastic feature about biodiesel is that you can make biodiesel at home. The equipment required for the entire process is simple and can be accessed at any local store or even from your garage. You would require steel or plastic drums, a pipe, a valve, a motor and a temperature gauging instrument.

Initially you should manufacture little amount of oil so that when you become acquainted with the process, you can make biodiesel at home at a larger scale.

The compounds needed for the reaction to take place are vegetable oil, lye (caustic soda) and Methanol. Lye has to be mixed with methanol first. This mixing should be done quickly because lye absorbs water from the atmosphere. This water content can produce impurities in the entire process. Methanol and lye combine to yield sodium methoxide. Now add vegetable oil to the blend and shake it with the help of a motor. Once the blending has taken place, the mixture is set aside to stand for at least 8-12 hours. This way the glycerin will sink underneath and biodiesel will emerge on top of it. The reason behind this phenomenon is the difference between the specific gravities of the two compounds. The glycerin can be removed from the bottom with the help of a pipe whose flow is controlled by a valve. Glycerin can further be utilized in making soaps and biodiesel for your vehicles.

Using the process mentioned above you can effortlessly make biodiesel at home.
