Members discovered that students eating in Market Central waste 29,600 pounds a year. Additionally, each dining student wastes an approximated 16.5 pounds of food annually. ‘ ‘ ‘ ‘ ‘ ‘ The calculations present a minimum statistic because the data was limited to food wasted during dinner and lunch hours Mondays through Fridays. So the results exclude breakfast every day and weekends altogether, which would have added to the overall food waste totals, said Free the Planet’s secretary Jessica Herbe. ‘ ‘ ‘ ‘ ‘ ‘ Some students might have noticed that the study inadvertently collected inedible pineapple rinds and bones. Volunteers realized the problem quickly but continued the method to remain consistent throughout the entire study. Because the inedible food was reliably collected, the results still reflect a difference in waste between days with and without trays that would not be influenced by this error, said Herbe. ‘ ‘ ‘ ‘ ‘ ‘ The study also notes that trays lead to wasted water because each tray takes about one-third to one-half of a gallon of water to wash. ‘ ‘ ‘ ‘ ‘ ‘ ‘Although the results do not have an accurate count of the number of people that use trays, the amount of water wasted on washing trays is obviously astronomical,’ said Herbe. ‘ ‘ ‘ ‘ ‘ ‘ The variation in waste between the two days will not change the regular policy regarding trays alone. Pitt and Sodexo will consider the results and student response before making any definite decisions, said Jodi Ludovici of Sodexo’s campus food services. ‘ ‘ ‘ ‘ ‘ ‘ ‘Sodexo … has a strategic initiative toward sustainability and recognize the significant results. However, student feedback is the main contributing factor,’ said Ludovici. ‘ ‘ ‘ ‘ ‘ ‘ Sodexo has converted many universities to trayless dining, including UC Davis, Georgia Tech, Rowan University, George Mason University, the University of Idaho and Buffalo State. Sodexo will collect students’ opinions on the potential change in person at Market Central, and it will also provide surveys if students wish to give criticism or approval, said Ludovici. ‘ ‘ ‘ ‘ ‘ ‘ Trayless dining reduces water, chemical and energy usage that lead to more efficiently run cafeterias. ‘ ‘ ‘ ‘ ‘ ‘ ‘At Sutherland, we are saving 200 gallons of water each day by our commitment to trayless dining,’ said Ludovici. ‘This totals to 43,000 gallons per year. Another way to look at it is 200 gallons of water saved per operational day for every 1,000 meals served.’ ‘ ‘ ‘ ‘ ‘ ‘ Pitt Professor of Business Administration Prakash Mirchandani explained the phenomenon that leads to this type of waste. ‘ ‘ ‘ ‘ ‘ ‘ Though trays provide a convenience to patrons, they lead to waste in a fixed-price buffet setting that does not necessarily occur in an a la carte cafeteria. They allow consumers to take any desired variety of foods without having to pay a higher cost. These extra rations might never be eaten when it actually comes time to sit down, said Mirchandani. ‘ ‘ ‘ ‘ ‘ ‘ ‘Eliminating trays will reduce both consumption and wastage. Avoiding overeating will have obvious health benefits for the students. But reducing food wastage will have some efficiency benefits as well,’ said Mirchandani. ‘ ‘ ‘ ‘ ‘ ‘ The elimination of trays leads to a more proficient operation at any buffet-style cafeteria through both the incoming and outgoing supply chains. Since a trayless buffet needs less food to run, it would be able to buy a smaller quantity of materials. Although it reduces the amount of food, the buffet still caters to everyone without as much waste. This also lowers the cost of transporting the unneeded food that would have otherwise been wasted, said Mirchandani.’ ‘ ‘ ‘ ‘ ‘ ‘ Market Central plans to go trayless every Tuesday and Wednesday until the end of the spring semester, including Earth Day on April 22. ‘ ‘ ‘ ‘ ‘ ‘ ‘Our goal would be to open fall ’09 trayless,’ said Ludovici. ‘The Perch at Sutherland opened trayless this last fall and is very well perceived.’
