What is Biodiesel and Why We Need it?

Biodiesel is an alternative fuel mainly produced from vegetable oil an animal fats. It is a renewable substitute of regular fuel. As a replacement of petroleum fuel it is much cleaner alternative. Its physical components are much similar to regular diesel fuel. In this article, you will find in detail what biodiesel is and why it is better than regular diesel fuel.

As mentioned before, renewable sources are used to create biodiesel. Sources like new or used vegetable oil and animal fats. These sources are not toxic and can be broken down by living organisms using a special process. To complete the process an alcohol, mostly methanol is used to create a chemical reaction with these oils and fats. After the reaction, we get a new liquid substance called fatty acid methyl esters. We call it biodiesel when we use it as fuel. In short, this is how we create biodiesel.

We mainly use biodiesel as fuel. It can be used directly or can be mixed with petroleum to use as fuel. This leads us to the question is there any benefit of using it instead of regular furl. The answer is yes. Scientific research confirmed that the use of biodiesel has a less harmful impact on human body. When regular fuel is used, out of all the chemicals that are emitted there are two major components responsible for cancer in human body. Biodiesel reduce the emission of those components by at least 13%.

Biodiesel has lots of positive impacts on human body and environment. It is time we use this alternative fuel much higher scale.
