Bio Diesel: A Concrete step towards clean and green Energy


What is Bio Diesel?

Bio-Diesel is a clean and sustainable alternative of conventional diesel fuel. It’s derived from edible or non-edible plant oils and feedstock. It consists of long-chain fatty acid esters. it can fully replace diesel or blended with diesel in any desired percentage. Unlike the vegetable and waste oils used to fuel converted diesel engines, Bio-diesel is a drop in biofuel. It means it is compatible with existing diesel engines and doesn’t require any alterations or changes made in the compression ignition or diesel engines. Use of bio-diesel can bring revolutionary shift in the way we consume fuel and go a long way in eliminating the carbon emission and curbing emission of Green House Gases (GHG) in the long run, It’s believed as the root-cause of global warming. 

Production of Bio Diesel:

World over, Bio Diesel is produced from renewable resources like edible or non-edible plant oil, and animal fats feedstocks. In India, though it’s a mandate to derive only from palm stearine, used cooking oil, waste oil and non-edible feedstock.

Process of producing Bio Diesel:

Bio Diesel is commonly produced by the trans-esterification of vegetable oil or animal fat feedstock and other non-edible raw materials such as frying oil etc. there are several methods of carrying out this trans-esterification. It is typically made by chemically reacting lipids such as animal fats, soybean oil or some other vegetable oil with small percentage of methanol, a catalyst to form Bio-Diesel. In essence, Bio Diesel is a ‘fatty acid methyl ester’.
In the process of producing Bio Diesel, Glycerine is also released, though in small proportions, which is a valuable product used to produce soap, cosmetic, paint and Pharmaceuticals.
