A study of 186,000 meals at 25 colleges and universities found a 25-30 percent reduction in food waste per person on trayless days. And since eliminating trays in September of 2008, it’s estimated that BU is also saving 35,000 gallons of water a week. These metrics were derived from the 2008 ARAMARK study, “The Business and Cultural Acceptance Case for Trayless Dining”,which reported that approximately .33 to .5 gallons of water is used per tray for every washing. While initial readings were not taken before the program was put in place, calculations are based on the 2,000 trays on campus being washed 35 times a week (on average 5 times a day), which total 70,000 a week.
