Cost of using permanent vs. disposable ware. Studies in two school systems.
In this study, the cost of using permanent ware and disposable ware in selected schools was compared. Included in the permanent ware study were the costs of: The ware, machine washing of the ware (including labor time and consumption of utilities, detergents, and chemicals), and refuse removal. Data collected in the disposable ware study were: Meal count; number of items of ware used; labor time; and cost of equipment, supplies, and refuse removal. The cost per student was 4 cents for permanent ware and 10 cents for disposable ware. Although the findings in the schools studied point to an economic advantage in using permanent ware, other considerations might prompt a decision in favor of disposable ware.
