Development of society increases the demand of energy. Particularly in transportation sector the need of diesel fuel is increasing day by day and consequently there is a problem of environmental pollution, so there are severe challenges to human survival and development. Biodiesel provides one kind of sustainable solution to above problems. The supercritical process is one of the innovative methods used in the manufacturing of biodiesel. With this process, oils are exposed to supercritical conditions, which are above their critical temperature and pressure. This allows for faster reaction rates and a higher production of biodiesel. Because supercritical fluids have certain qualities that improve extraction and conversion, this method is quite effective. The use of ultrasonography to help the procedure is another novel strategy. In order to improve mass transfer and mixing in the reaction mixture, cavitation is created using ultrasonic waves. It is possible to produce biodiesel from various animal fats, vegetable oil and algae. There are various techniques of converting oil into biodiesel. This part discusses emerging and new techniques such as super critical process, ultra sound assisted process and micro wave assisted process for producing biodiesel.
