Biodiesel production from waste cooking oil: A brief review

Biodiesel is a source of new renewable energies and substitute fuel with much potential in the future for petroleum-derived diesel. According to BP Statistical Review World Energy, total global consumption diesel from petroleum increasing one decade which 3.5 million tonnes 2010 3.9 2019. Despite reducing dependence on fossil fuel, question how waste cooking oil (WCO) disposal related environmental damage issues might be solved by biodiesel production. In Malaysia, an estimated 540 000 WCO vegetable animal fats are discarded each year without being treated as wastes. recognize raw material process have great potential. made through reaction between triglyceride alcohol, found primarily plants animals. Transesterification popular production low cost mild reactions conditions. Some studies done variable transesterification optimum condition WCO. This study examines production, including various variables comparison
