Biofuel, is any fuel that is derived from biomass—that is, plant or algae material or animal waste. Since such feedstock material can be replenished readily, biofuel is considered to be a source of renewable energy, unlike fossil fuels such as petroleum, coal, and natural gas.
Biofuel is commonly advocated as a cost-effective and environmentally benign alternative to petroleum and other fossil fuels, particularly within the context of rising petroleum prices and increased concern over the contributions made by fossil fuels to global warming.


Biodiesel is a renewable, biodegradable fuel manufactured domestically from vegetable oils, animal fats, or recycled restaurant grease.
Biodiesel is a liquid fuel often referred to as B100, pure, or neat biodiesel in its unblended form. Like petroleum diesel, biodiesel is used to fuel compressionignition engines.
Biodiesel is made through a chemical process called transesterification whereby the glycerin is separated from the fat or vegetable oil. The process leaves behind two products – methyl esters and glycerin. Methyl esters is the chemical name for biodiesel and glycerin is used in a variety of processes, including soap production.


Biogas is an environmentally-friendly, renewable energy source produced by the breakdown of organic matter such as food scraps and animal waste.
Biogas is a renewable fuel that’s produced when organic matter, such as food or animal waste is broken down by microorganisms in the absence of oxygen. This process is called anaerobic digestion. For this to take place, the waste material needs to be enclosed in an environment where there is no oxygen.
Biogas can occur naturally or as part of an industrial process to intentionally create it as a fuel.


    According to researchers at the University of Idaho and the U.S. Department of Agriculture, for every fossil fuel energy unit needed to grow and refine soybeans for biodiesel, four and a half units of energy are generated. With petroleum diesel, less than one unit of energy is generated in return.
    Opting for renewable energy like biofuel will help reduce the producing country’s dependence on foreign oil in combination with other sustainable measures.
    Gasoline releases nitrogen oxide and acetaldehyde in the air forming smog pollution and causing lung diseases, cancer, etc… Using biodiesel or biomethane significantly reduces the particulates being released into the air, leading to better air quality and far less pollution.
    Biodiesel production has had a wildly positive impact on the economy over the last twenty years. For example, According to Biofuels Journal, biodiesel production was at about 500,000 gallons in 1999. Just ten years later, in 2009, it was at 545 million gallons. That added a whopping $4.28 billion to the gross domestic product.
    Biofuel can help significantly reduce greenhouse gases that contribute to global warming. In fact, one study out of Australia showed that the use of biodiesel made from cooking oil could reduce greenhouse gas emissions by as much as 87 percent.
    A significant benefit of using biogas or biofuel is that it’s more sustainable than its fossil fuel counterpart. Fossil fuels are a finite resource; one day, the world will run out. On the other hand, biofuels are renewable energy made from plants. Compared to traditional fossil fuels, the possibilities for biofuels are seemingly endless.
    Biofuels can be used in existing diesel engines with little or no modifications necessary to the system. In most of these vehicles, the performance is the same, if not better. Studies have shown that biofuels also help engines last longer since they do not have a high viscosity rate.
