Abstract: Under the background of waste classification and “zero waste city” pilot construction in China, the current management status and the existing problems were systematically sorted out and deeply analyzed. Through the collection of government statistical data and the extraction of Chinese and English literature data, it was estimated that the generation of food waste in China in 2017 was approximately 158 million tons, which included 63 million tons of restaurant food waste. The results showed that temporal and spatial discrepancies existed in food waste generation, characteristics, and treatment capability across different regions. Although the utilization of food waste in China has been significantly developed, a few problems still need to be solved, such as insufficient attention attached to source reduction, deficiency in treatment capacity, low efficiency in treatment technologies, lack of performance evaluation methods, etc. It was suggested that all regions should combine the waste classification and the “zero waste” construction according to local conditions, improve the reduction and resource utilization of food waste and make up the gap in treatment capacity continually. The government, enterprises and institutions, residents and other parties should jointly participate in the whole process of food waste management. By standardizing and evaluating the performance of mainstream technologies, and supervising the actual operation of food waste treatment projects, a multi-dimensional evaluation methodology should be established to realize the quantitative analysis of environment, resources and cost of food waste management from a life cycle perspective, so as to provide scientific basis for effective decision-making of the government and the industry in the future.
