The population of the vehicle has increased around the world within the last few decades. This increased vehicle population has made the path for many economical and environmental issues. These difficult situations forced the governments to set regulations on emission methods and seek another fuel choice.

The use of alternative fuels is the upsurge issue in today’s world for public health, environment, national energy needs, and the non-sustainability of fossil fuels.

The alternative fuel is also called non-conventional fuels which is a substance used like a fuel. The alternative fuel is an energy source which is renewable. The examples of alternative fuels are biodiesel, bioalcohol, natural gas, vegetable oil, chemically stored electricity, hydrogen, non-fossil methane, and biomass sources.

Biodiesel is mentioned as a vegetable oil or animal fat which depends on diesel fuel including long-chain of alkyl and esters. Typically, it is formed from chemical reaction of lipids like vegetable oil and animal fat with an alcohol. This procedure is called Transesterification. It is very easy to use, nontoxic, biodegradable, and importantly it does not have sulfur and aromatics.

Biodiesel is a user friendly. It decreases to be dependent on foreign oil. It lubricates the engine and reduces the engine wear. It is used in diesel without any changes.


The Alternative Fuels Mechanical Seminar paper concludes on biodiesel which is formed from transesterification of the vegetable oil or animal fat. There are many steps to perform this transesterification reaction. The reaction is the method of interchanging ester’s organic group with the organic group of alcohol. This reaction is catalyzed by adding acid or base.
