As the nation’s battle against food waste intensifies, the authorities are making sure they know their enemy better. In December, the National Environment Agency (NEA) is expected to start a waste audit of shopping malls, hotels, supermarkets, hawker centres, food manufacturing and food catering establishments, as well as food warehouses. The project, which will end in mid-2019, will categorise approximately 100kg samples of the waste, according to documents seen by The Straits Times.
