How much of your food are you literally throwing away? How much do you know about Hong Kong's food waste problem? In barely a year, we generate about 1.3 million tonnes of food waste. 1.3 million tonnes of food waste can fill up either 3,488 Olympic-size swimming pools or 65,408 lorries, each weighing 20 tonnes, which can queue the G4 Beijing-Hong Kong-Macau Expressway running from Hong Kong, Shenzhen and reaching Zheng Zhou. It is estimated that 1.3 million tonnes of food waste can feed 20 million people in hunger. In 2011, Hong Kong generated over 3,584 tonnes of food waste daily, accounting for about 40 per cent of municipal solid waste, and was disposed of at landfills every day. Hong Kong is running out of landfill space far earlier than expected. The disposal of food waste led not just a high cost of handling but a formation of methane, a potent greenhouse gas, imposing severe burden to our environment. Food waste in landfills also causes odour as it decomposes. Worst of all, food waste is a drain on natural resources.
