The Circular Economy-Oriented Practice in the Food Manufacturing Industry
The food manufacturing industry can be fragmented into various sub-sectors according to different kinds of food processing and manufacturing methods. The National Bureau of Statistics of China has classified the industry into seven categories: bakery manufacturing; confectionery, chocolate and candied fruit manufacturing; instant food manufacturing; liquid milk and dairy manufacturing; canning; manufacturing of condiments and fermented products; and manufacturing of other food. Most of the foods are processed in a simple way except condipments and fermented products which feature bulk production and complicated processes. Their manufacturing involves several biotransformation reactions and separation processes, while large amounts of by-products and many kinds of pollutants will be generated in the process, creating huge potentials of developing the circular economy in the sector.
