Top 7 Advantages of Biodiesel

As we strive towards a green earth and towards reducing the levels of greenhouse gas emissions, we have to find fuel alternatives. One fuel alternative is biofuels, which emit less pollution in comparison to fossil fuels.

As gas prices keep rising, and global warming more prevalent, the world it turning towards biofuel to reduce costs and to protect the environment. Biofuels release fewer greenhouse gases such as carbon dioxide and help to reduce gases that trap heat. Biofuels exist in three forms:

  • Solid: Dried plant material, manure or wood
  • Gaseous: Biogas
  • Liquid: Bioethanol and biodiesel

In this article, we shall discuss the benefits of biodiesel:

Biodiesel is a first-generation biofuel, and it comes from waste cooking oil, animal fats/oils, tallow or vegetable oil. The most biodiesel currently produced by oil recycling companies comes from waste cooking oil. The waste oil mainly comes from restaurants, fast food joints, industrial food producers, and individual home users. The benefits of using biodiesel over diesel include:

It Is Renewable Energy

Biodiesel is a source of renewable energy. Renewable energy is derived from natural resources that are constantly renewed, such as sun, wind, geothermal heat, etc. Fossil fuel form over millions of years and is not termed as a renewable energy source because it would take millions of years to replenish.

Biodiesel is derived from vegetable oils and animal fats, and the production of the diesel can happen on demand.

Does Not Require A Special Engine

A significant advantage of using biodiesel is that it does not require a particular type of engine. Any diesel engine or oil heating system with minimal or no alterations can use biodiesel. You can use biodiesel in its pure form, or blend it with petroleum diesel. For example, B20 is a mixture of biodiesel and diesel.

Biodiesel Prolongs Your Engine’s Life

Biodiesel contains higher ratings of cetane and better lubricating capabilities than sulfur types of diesel. These two properties help in reducing the wear and tear in your fuel system. The absence of sulfur in biodiesel helps to extend your engine and catalytic converter lives.

Biodiesel Emits Fewer Greenhouse Gases

Fossil fuels have been the source of greenhouse gases that destroy the ozone layer. The destruction of the ozone layer causes changes in climate, destabilizes weather patterns, and is a significant cause of global warming.

Biodiesel in place of petroleum diesel is cited for causing a significant reduction in greenhouse gases. B20, a blend of pure biodiesel and petroleum diesel can reduce carbon dioxide by 15%

Biodiesel Has a Higher Flashpoint

Petroleum diesel has a flashpoint of 52, while biodiesel has a flashpoint of more than 152. This difference in flashpoint means that petroleum diesel is more combustible and poses a more significant fire risk than biodiesel. Biodiesel is more comfortable to transport, store, and handle in comparison to petroleum diesel.

Economy improvement

Vehicles that use biodiesel are infinitely more economical in fuel usage than diesel engines. The biodiesel run engines consume a lower amount of gas and run for more miles for every gallon consumed.

Production of biodiesel locally helps to employ thousands of individuals in the biodiesel production plants. Waste cooking oil that would otherwise go to waste is bought off individuals by oil recycling companies, creating incomes for many people in that chain.

Health Benefits

Pollution in the air is one of the major causes of diseases, some of which are fatal. Contaminants emitted from petroleum engines cause smog and global warming. These pollutants, as a result, cause thousands of sicknesses per year. Biodiesel does not emit toxic pollutants and is an overall benefit for the environment and people’s health.


The global warming effects will become progressively worse if nothing is done about greenhouse gas emissions. As more campaign is done on the subject, there is increased awareness on the same. Oil recycling companies buy waste oil from restaurants and food production companies and produce biodiesel in an attempt to reduce environmental degradation. With time, fossil fuel will run out because consumption is higher than replenish. All we shall be left with is biofuel, and with it, greener earth.
