The guide helps anyone working in schools (students, teachers, administration, nutrition staff, etc.) to organize and execute a food waste audit in their cafeteria.

At the end of the guide, the U.S. Department of Agriculture and U.S. Environmental Protection Agency recommend some strategies to help schools reduce food waste.
