All three of ISU Dining's residential dining centers have "gone trayless" with the support of students, in order to decrease the amount of food waste that is generated daily by each dining location. By going trayless, guests pick up less food and therefore, waste less when they are finished with their meal.
Prior to going trayless in 2009, Union Drive Marketplace's amount of food wasted per guest was 0.36 pounds. This same year, Season's Marketplace was converted to trayless dining and the amount of food wasted per guest was only 0.22 pounds. By going trayless, we are saving about 0.14 pounds of food waste per person each day.
