A Review on Comparison of Some Edible, Inedible and Waste Oil Sources with Algae for Biodiesel Production

The present biggest challenging task in front of the world is to search new energy source. Apart from the all energy sources, biodiesel was the only dominant alternate energy to accomplish the fossil-fueldemand in the transport sector which consist a diesel engine. Biodiesel production from edible, inedible feed stocks causes food versus fuel and greenhouse-gas emissions problem. It is observed that yields of edible, inedible oils and animal fats are very less compared to third-generation feedstocklike Algae: It is one of the fastest growing organisms. It is environmentally friendly because it captures Carbon dioxide (CO2) from the environment to grow. According to the Indian scenario, this is the right time to fix attention on algae biodiesel, to meet the fossil-fuel demand. The higher heating value ofbiodiesel is slightly lesser than that of diesel, but higher than coal. Biodiesel combusts same like diesel fuel, concerns regulate emissions, and doubtlessly better efficiency than diesel fuel. Algae biodieselhas good physicochemical properties than others. This paper reviews the comparison of yield, fatty acid composition of oil, presently available methods to convert algae into biodiesel and its effect onDirect and Indirect injection diesel engines. Literature reveals that a reduction in exhaust emissions with slight compromise in performances are possible with the usage algae as a biodiesel
