According to the report of the State of Food Security and Nutrition in the World released by the Food and Agriculture Organization of the United Nations in 2022, the number of people affected by hunger globally has reached 828 million in 2021, an increase of about 46 million compared with 2020. However, according to the Food Waste Index Report of the United Nations Environment Programme, a total of 931 million tons of food was wasted in the world in 2019, accounting for about 17% of the globally total consumable food.

From field to dining table, the planting, production, storage, transportation and processing of grain are not easy. At the same time, food waste also means a lot of waste of water, energy, land, means of production and other resources, and it also increases additional environmental loads such as water pollution, soil pollution and greenhouse gas emissions. According to experts’ estimates, every kilogram of grain produced will consume about one ton of water.  While every kilogram of grain wasted, more than two kilograms of carbon dioxide will be emitted.
