What are Biofuels? This is the Definition of Biofuel and its Types

 

There are many fuels on Earth, one of which is biofuel. Biofuels are fuels made from living things, usually plants.

Biofuels are environmentally friendly fuels. Biofuels can be divided into several types, namely bioethanol, biodiesel, and biogas.

• Bioethanol
Bioethanol is alcohol derived from plants, such as wheat, sugar cane, corn, cassava, sweet potatoes, fruits, and vegetable waste.

To get alcohol, the plants above must go through a fermentation process first.

This alcohol can be used as vehicle fuel. In order to be used as fuel, we must mix it with gasoline with a certain dose.

In fact, some bioethanol can be used as fuel without having to be mixed with gasoline. This fuel is more efficient and environmentally friendly.

• Biodiesel
Biodiesel is a fuel made from soybean oil, rapeseed oil (a type of flower), castor fruit oil, to sunflower oil.

In Hawaii biodiesel is made from used cooking oil. While in Japan the biodiesel is made from used oil from restaurants.

Biodiesel can also be made from animal oil, but most countries in the world make it from plants. This fuel is more environmentally friendly than diesel.

• Biogas
Biogas is a fuel derived from the fermentation of plant waste or waste (human or animal).
When fermented, the garbage or dirt will emit gas. This gas is known as biogas.

Biogas is usually used to power electricity or stoves. Biogas is much cleaner than coal.
In addition, the energy produced is greater and the carbon dioxide produced is also less.
