Summary: Biodiesel, as a renewable and clean energy source to replace fossil fuels, has gained attention worldwide for reducing regulated exhaust emissions through the use of ionic liquids catalysts combined with alcohol and waste oil for catalytic transesterification. However, the running cost of this process remains higher than traditional chemical transesterification. Non-edible sources like waste oil, non-edible vegetable oil, and waste animal oil are commonly used for biodiesel production due to their low cost and independence from the food chain.
