Biodiesel has also been paid greater attention in recent years because fossil fuel sources are limited and there is a need to look for alternatives to fossil fuels to ensure environmental protection and energy security. Biodiesel is non-toxic, renewable and biodegradable and is considered as one of the most alternative fuels for diesel engines. Biodiesel is prepared from various sources including edible oils, non-edible oils, animal fats, legume plants, etc. There are more than 350 oil bearing crops identified [10], among which only sunflower, palm, soybean, jatropha oils are considered as potential alternative fuels for diesel engine. Edible vegetable oils and animal fats for biodiesel production have become more expensive as they compete with food materials. In recent years there is an increased demand for vegetable oils since they are edible and hence they are not preferred much for biodiesel production [5]. MM GuiK et.al [18] mentioned currently, more than 95% of the world biodiesel is produced from edible oil which is easily available on large scale from the agricultural industry. However, continuous and large-scale production of biodiesel from edible oil without proper planning may cause negative impact to the world, such as depletion of food supply leading to economic imbalance. A possible solution to overcome this problem is to use non-edible oil or waste edible oil (WEO) as a feedstock. Trans-esterification is a chemical reaction to produce biodiesel ( fatty acid methyl ester) by involving triglycerides and an alcohol as reactants in presence of suitable catalysts such as strong alkali, a strong acid and an enzyme. The main factors affecting transesterification are free fatty acid(FFA) content, the molar ratio of glycerides to alcohol, catalyst, reaction temperature and pressure, reaction time and the contents of free fatty acids and trace water content in oil. The commonly accepted molar ratio of alcohol to to glycerides are 6:1-30:1, temperature 40-70C, time period 30-120 minutes and mixing rate is 400-900 rpm. In this paper an attempt has been made on review of potential source of non-edible oil of Indian origin for production of biodiesel and the researches done by various researchers in this field and their finding on biodiesel production technologies, potential catalysts and effect of reaction parameters on biodiesel yield potentials. This review paper covers the works of researcher published during 2000 to 2018.
