The world of buffet style cafeterias and "late night" options can be a college kids dream come true, but may be adding to food waste numbers across the nation, not to mention the waistline of students.
Many colleges in the US have decided to take the tray-less approach as a way to save money and cut this food waste epidemic.
Going tray-less can have multiple benefits including reduced chemical use from washing the trays, reduced overhead costs from buying new trays and less food waste.
Trays were invented as a tool to help students cary more food and helping to make less trips. These days, however, they are contributing to, in addition to food waste, laziness and obesity.
By opting out of the tray and taking just what you need, knowing you can come back for seconds if need be, could help students health, and cut down on waste and money spent for the dining halls, says Carla Lansiti.
