Abstract: With the rapid development of the world economy and industry, the demand for energy is constantly increasing. Promoting the resource utilization of kitchen waste oil and vigorously developing the production of biodiesel from kitchen waste oil have important significance for achieving China’s “dual carbon” goal and promoting the construction of ecological civilization. The production of kitchen waste oil in China is increasing day by day. The effective utilization of kitchen waste oil can not only prevent the food safety problems caused by its back-flow to dining tables, but also solve the environmental pollution problems caused by random discharge. The relevant management policies of kitchen waste oil in China and the collection and transportation models at home and abroad were introduced. The current situation of collection and transportation of kitchen waste oil in Shanghai was analyzed, and the management status at home and abroad was compared. At the same time, the current situation of resource utilization in Shanghai was analyzed and studied. At present, there are some problems in the collection and transportation of kitchen waste oil in Shanghai, such as limited supply capacity of raw materials, uneven quality of oil supplied by suppliers, difficulty in meeting oil collection standards for kitchen waste oil, and significant impact of region and process on pre-treatment costs. In terms of resource utilization, there are problems such as uneven treatment facilities, failure to use facilities according to regulations after installation, and low added value of resource utilization products. Finally, relevant suggestions were put forward from the aspects of standardizing and improving the recycling standards of kitchen waste oil, researching and formulating policies for the resource utilization of kitchen waste oil, promoting technological innovation and industrial upgrading, establishing and improving the whole process supervision platform of kitchen waste oil. Especially in the context of “dual carbon”, exploring the introduction of carbon offset mechanisms was innovatively proposed to replace the current subsidy policies, which has a long-term incentive effect on the sustainable development of biodiesel enterprises.
