Biodiesel Production from Waste Cooking Oil Using Mechanical stirring and Ultrasonic Cavitation method

Energy security and air pollution is the challenging issues now days. Biodiesel is an effective alternative fuel. In present study, biodiesel is prepared using waste cooking oil. Mechanical stirring and ultrasonic cavitation method is used to draw biodiesel. Present study showed that mechanical stirring method provides higher yield % as compared to ultrasonic cavitation method. The reaction time in case of ultrasonic cavitation is significantly lesser as compared to mechanical stirring method.
