In the fall of 1993, a new food system was implemented in the Village One and Village Two cafeterias with the hope of reducing the amount of waste generated in these areas. The aim of this study was to measure the amount of waste generated before and after the implementation of this system so as to detect any change in waste production that may have occurred.

The debit card system has had an overall positive effect on the amount of waste generated in the Village One kitchen and cafeteria. Under the "all you can eat" system students could fill their plates with as much food as they wanted at no extra cost and throw their food away if they did not like it or could not finish it all. Since students now pay the value of the food they consume under the debit card system, they buy less food and therefore throw away less.

The scrape room area shows the largest reduction in waste with a decrease of 71.26% in the amount of food waste thrown away by students. The amount of total kitchen waste produced in Village One has gone up under the debit card system by 1.71%. The total kitchen and cafeteria waste has decreased by 37.29% (without salad room) under the debit card system and 46.65% when salad room garbage is included. The impact of the debit card system on the waste produced in the Village One kitchen and cafeteria has been positive. Much less waste is produced now as compared to when the Ůall you can eatÓ food system was in place. However, this reduction is almost exclusively due to the large decrease in scrape room waste (71.26%). This reduction is so high that the increase in kitchen waste does not have a large impact on the total kitchen and cafeteria waste generated overall.
