Disposal of discarded used-frying oils in lakes, rivers and use as feed for animals is a matter of serious concern because it can result in the return of harmful compounds back into the food chain. It is therefore necessary that discarded fried oil is recycled carefully and efficiently. One of the alternatives to recycling is conversion of discarded frying oil into biodiesel. Biodiesel, a fatty acid methyl ester, is a nontoxic biodegradable alternative to fuel (oil/gas). Cooking oil which is discarded after use in food industry can be employed as an economical resource for the production of biodiesel. Biodiesel obtained from discarded frying oil has been found to give better engine performance and lesser carbon emission as compared to other fuels. However, the properties of biodiesel manufactured by using discarded cooking oil are dependent upon the content of free fatty acids, polar compounds and polymerized triglycerides. This review paper covers the key concerns associated with conversion of waste frying oil into biodiesel. In this review paper scientific research and review papers (N=50) were collected via several electronic database such as Medline (Pub-med Version), NLIST (Program of INFLBNET) and DELNET-India (Developing library network).
