Biodiesel production involves the transesterification process, where the triglyceride lipid source converts as fatty acid methyl esters and glycerol. A large amount of waste cooking oil is produced globally and will dispose of the available energy. According to the Health Laws of Waste Cooking Oil, it does not need to be recycled in the food industry. In this research, the main objective was to create a small and medium-sized enterprises (SME) plant for the production of biodiesel from improving the process requirements and from waste cooking oil. The product can be used in place of petroleum diesel for automotive and industrial applications without any environmental impact and ensures the same performance of internal combustion engines with essential changes. The aim is to develop an automated machine to produce biodiesel from waste cooking oil. The machine is building alternative methods for re-use of waste cooking oil to make biodiesel. Biodiesel can be used to produce waste vegetable oil as a raw material. Waste vegetable oil is easily available and cheaper and the process of converting waste vegetable oil into biodiesel takes time, and biodiesel production requires an operator to run the system. Due to these requirements, a typical biodiesel system requires much operator interaction which is not overcome by the existing system. The system was designed and built in conjunction with pumps, valves, temperature sensors, etc., to completely handle the production of biodiesel with minimum operator interaction. The developed system circulates the fluid throughout the system and presenting the end user with biodiesel upon completion of a full cycle.
