Background

The kitchen waste oil is a mixture of waste edible oil after cooking, and is mainly residual oil after food is fried in restaurants, households and food processing points or waste oil recovered from a smoke exhaust ventilator. Compared with the grease before use, the grease has dark color, large viscosity, increased acid value and peroxide value and deepened rancidity degree.

After the edible oil is used for a long time at high temperature, the nutritive value is obviously reduced, even a plurality of pathogenic components are generated, and the edible oil is not good for the health of human bodies after being eaten for a long time. In recent years, illegal vendors collect waste kitchen oil after being cooked for many times in restaurants, dining halls and the like, prepare the waste kitchen oil into 'hogwash oil' through simple treatment, sell the hogwash oil to small vendors, continue to use the hogwash oil when processing deep-fried dough sticks, pastries and marinated vegetables, and seriously harm the health of people. If the waste oil is directly discharged into a sewer, the waste oil not only blocks and corrodes pipelines, but also causes water surface pollution and water eutrophication in severe cases due to high content of fatty acid.

The waste cooking oil is a good chemical raw material, and can be widely used in various industries such as plastics, wool spinning, pesticides, printing and dyeing, rubber and the like after being processed.
