International Biodiesel Day -

Updated on by

International Biodiesel Day, recognized annually on August 10th, is a global observance dedicated to promoting and exploring the use of biodiesel, an environmentally-friendly and renewable source of energy. The date commemorates the day when Rudolf Diesel ran an engine on peanut oil in 1893, marking the invention and acknowledgement of biofuels.

The aim of this observance is to generate awareness about non-fossil fuels and encourage the development and use of biodiesel worldwide, contributing to the conservation of our environment.

History of International Biodiesel Day

The advent of biodiesel can be traced back to Sir Rudolf Diesel, a German inventor, and maverick mechanical engineer. It was on the 10th of August, 1893, that Sir Diesel first used peanut oil to power an engine. This was a landmark demonstration of the potential of vegetable oil as a source of fuel, paving the way for the development of biodiesel.

While Sir Diesel’s experiments laid the preliminary foundation in the 19th century, biodiesel emerged in the spotlight of the energy sector primarily during the late 20th century. This was a period marked by escalating environmental concerns and the search for sustainable renewable energy alternatives. The energy crisis of the 1970s and mounting evidence of global warming expedited by fossil fuels use further augmented the relevance of biodiesel.

In order to celebrate the ingenious contributions of Sir Rudolf Diesel and to underline the significant role of biodiesel as a renewable and eco-friendly fuel source, the 10th of August is globally recognized as International Biodiesel Day.

The goal of International Biodiesel Day is to raise public awareness regarding the use of biodiesel as an alternative to fossil fuels. It is an occasion to highlight the benefits of biodiesel - a high energy, clean-burning fuel, and to stress how it can be a sustainable answer to our energy requirements, thereby helping to reduce reliance on harmful fossil fuels. Around the world, this day is marked by various events and educational initiatives aimed at promoting the widespread adoption of biodiesel.

8 Interesting Facts About Biodiesel


Biofriendly Fuel

Biodiesel reduces greenhouse gas emissions. Compared to petroleum diesel, it releases 41% less carbon dioxide.


Recyclable Resource

Biodiesel's primary components can be obtained from recycled cooking oil, grease, or any fat of animal or plant.


Algae as a Biofuel

Aquatic organisms like algae and seaweed have potential to produce biodiesel due to their oil content. It's being researched as a sustainable biofuel option.


Engine Friendly

Biodiesel acts as a solvent, which helps to clean the engine. It might increase the life of vehicles' engines compared to those using traditional diesel.


Energy Density of Biodiesel

Biodiesel has a high energy density. About 1kg of biodiesel releases around 37MJ, very close to diesel's 45.6MJ.


Non-toxic Fuel

Biodiesel is non-toxic, renewable, and biodegradable. It's safe to handle, store, and transport.


Early Diesel Engines

The original diesel engines were actually designed to run on peanut oil, proving that the idea of bio or vegetable oil as a fuel source is not new.


Biodiesel in Extreme Temperatures

In very cold temperatures, biodiesel can become solid and cause issues in engines. So, various additives are used to prevent this.
