Shengkui CHENG, a researcher from the CAS Institute of Geographic Sciences and Natural Resources Research, made an analysis on almost 7,000 tables and 366 restaurants in Beijing, Shanghai and the southwestern cities of Lhasa and Chengdu. The team interviewed hundreds of people, collated 7,500 questionnaires and weighed 32,000 dishes. From their data, they estimated that enough food is discarded in restaurants annually in China to feed between 30 million and 50 million people. The data were presented last November at the Food Waste Forum in Beijing. The researchers conclude that consumers should be more conscious of the amount of food waste they generate and minimize their personal food waste
