Since eliminating trays in September of 2008, it’s estimated that BU is saving 35,000 gallons of water a week.
This metric was derived using 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 2,000 trays on campus being washed 35 times a week (on average 5 times a day) or 7,000 washes per day.
Going trayless also:
- Reduces dependence on fossil fuels by eliminating the need to heat water for washing
- Saves between one third and one half gallon of water per tray
- Reduces the purchase and use of detergents and drying agents
- Reduces food waste into landfills, incinerators, and wastewater treatment facilities
- Supports education and awareness of environmental issues
- Reinforces sustainability initiatives
- Encourages students to participate in sustainable initiatives that have both personal and community impact
