Diners using trays more likely to return crockery: NEA survey
Diners were more likely to return items when they were using trays, than when they were not, according to the results of a month-long pilot conducted at three food centres by the National Environment Agency (NEA).
Among those who ate without trays, the probability of people returning their crockery was highest for those who were only eating, followed by those who were eating and drinking, followed by those who were only drinking, said the agency which released its findings on Sunday. The NEA also found that the tray return rates were lowest between 3pm and 5pm.
Under the NEA pilot, the tray return initiative has been rolled out at four hawker centres at 726 Clementi West Street 2, Kallang Estate Food Centre, 137 Tampines Street 11, and 628 Ang Mo Kio Ave 4.
Last month, the NEA conducted observation surveys at three of the centres at Clementi, Kallang and Tampines. Nearly 18,000 trays were returned. The most encouraging response was noted at the Tampines Round Market, with an average of 280 trays returned per hour.
