The change in industrialisation and the increase in usage of automobile divesting the natural reserves of the fossil fuels which has driven the world towards alternative fuels especially renewable sources. One of the most prominent replaceable alternatives to the diesel is biodiesel. The research on usage of this biodiesel and modification of engines to suit these biodiesels started during the period of World War-II and the change in environmental conditions and decreasing reserves of the existing petroleum reserves formed as catalyst to accelerate this research to find better alternative biodiesel. Wide research is being done on many of the alternative biodiesels. This work mainly focuses on review of performance, emission and combustion characteristics of five most prominent biodiesels namely Jatropha, Cotton seed oil, Rubber seed oil, Mahua oil and Rapeseed oil. It is found that the brake specific fuel consumption is high for all the biodiesels because of less energy content in them in comparison with diesel. The variation of brake thermal efficiency depends on the percentage of fuel combustion and the percentage of blends used. From the review it was observed that. Even though the report of emission characteristics shows that the emissions of HC, smoke and CO by Rapeseed oil is little more comparative to that of other biodiesel blends but the performance of Rapeseed oil is superior and almost similar to that of diesel when compared with other biodiesel blends. Hence forth Rapeseed oil can be suggested as better alternative biodiesel to the diesel with certain modifications like Al 2 O 3 coatings to the piston which controls CO and HC emissions.

“…Edible oils are the main feedstock for biodiesel, which makes production costs high and impacts negatively on food security . Proposed solutions to these problems have included the use of nonedible feedstocks such as jatropha, palm fatty acid distillate, animal fat, waste yellow grease, oil extracted from spent coffee grounds, oil and grease extracted from municipal sewage sludges, oil recovered from palm oil mill wastewater, and fish processing wastes . The utilization of waste oils is especially environmentally friendly since it reduces the discharge and disposal of the waste …”

Biodiesel is a renewable fuel commonly used to replace diesel. Currently, biodiesel production is controversial in food security circles because edible oils are used as biodiesel feedstock. This study investigates the use of nonedible oil, recovered from biodiesel wastewater (BWW), as an alternative feedstock for biodiesel production.BWW was treated with acidification with H 2 SO 4 to recover the oil phase from the water. The major components of the recovered oil, 56.9 wt% ester and 38.1 wt% free fatty acids (FFA), demonstrated its potential as a feedstock for biodiesel production by esterification. The optimal conditions for biodiesel production from the recovered oil were 5 wt% H 2 SO 4 , a 2:1 M ratio of ethanol to FFA, a reaction temperature of 70 C, and a reaction time of 120 min. These conditions produced biodiesel with a purity of 97.7 wt% and a yield of 98.5 wt%. Additionally, the oil recovery process greatly reduced the pollutant load in BWW, bringing the cost of treatment below the usual cost of treating BWW with a high content of organic matter.
