Although the experiments carried out herein used a low power ultrasonic bath, which would probably be used in large scale processing, the amount of energy invested in the reaction was 1025 kJ mol−1 under optimal conditions, considering the both heating and ultrasonic application. Thus, the amount of energy invested was lower than the energy gained during the reaction. The EROI for the process was 2.1, so the process for biodiesel production could be considered viable from a heat of combustion point of view. The EROI of the process drops to 0.3 when the energy needed to extract the oil is considered, caused by the high demand for energy by the extraction process. Under this condition, the use of SCG oil would not be energetically viable for biodiesel production, but could be economically viable for other applications such as pharmaceuticals.
