To curb food waste, on the one hand, we need to strengthen the institutional constraints, vigorously advocate the "CD-ROM action", the catering industry, unit cafeteria, official activities, schools, families, as well as individuals, and other different subjects respectively, the system norms and constraints, strengthen the supervision and inspection efforts.

On the other hand, we should correctly guide the concept of consumption, the requirements of food saving into the citizens' convention, village rules and regulations, industry norms, etc., to strengthen the public opinion of food saving publicity, and continue to promote the change of customs, so that food saving, against waste in the whole society has become a trend.

In terms of supply chain management, Cao Hui said that we should innovate the food processing and distribution model, support the catering units to make full use of the central kitchen, accelerate the construction of staple food distribution centers and cold chain support system, while promoting the resourceful use of food waste.

China has the most waste in the consumption chain, mainly catering waste:

Cao Hui said. A report by the Chinese Academy of Sciences shows that from 2013 to 2015 our catering food waste was between 17 million tons and 18 million tons per year, equivalent to 30 million to 50 million people a year rations. In recent years, this number is gradually shrinking as the country's anti-waste regulation continues to increase.
