REDUCING FOOD WASTE IN SCHOOLS: THE BUSINESS CASE

A WWF study of 46 US schools found that students waste an average of 39.2 pounds of food and 28.7 cartons of milk annually. This translates to an estimated $1.7 billion in national annual losses. The report highlights that milk waste is particularly high due to misconceptions about USDA reimbursement rules and the use of cartons over dispensers. It proposes that reducing waste—even by a conservative 3%—could provide significant funding for initiatives like Farm to School (F2S) and the Good Food Purchasing Program (GFPP), which improve student nutrition and support local economies.

• A study of 46 schools across 8 US states revealed that students waste an average of 39.2 pounds of food and 28.7 cartons of milk per year. When extrapolated to the nearly 100,000 public schools in the US serving 29.6 million students daily via the National School Lunch Program (NSLP), this results in an estimated $9.7 million thrown out daily, totaling $1.7 billion annually.
• Milk waste is a significant contributor to financial and environmental loss, with an estimated 45 million gallons wasted annually in the US, costing approximately $138 million. A primary driver is the mistaken belief among staff that students must take milk for the school to receive NSLP reimbursement, although students do not actually need to take it for a meal to be reimbursable.
• The method of milk delivery significantly impacts waste levels. Students using cartons wasted an average of 155 cartons per year, compared to 67 for those using jugs and 27 for those using dispensers. In Clackamas County, Oregon, a milk dispenser program reduced milk purchasing by 40% and increased sales by approximately 40%.
• Simple measurement and auditing can lead to immediate waste reduction. In the WWF study, participating schools reduced food waste by an average of 3% per student by the end of the school year, with elementary schools seeing a 14.5% reduction, despite having no formal waste reduction interventions.
• Savings from food waste reduction can be reinvested into the Farm to School (F2S) program to bridge funding gaps. A conservative 3% national reduction in waste would provide approximately $52 million, covering more than half of the $95 million gap between USDA F2S grant requests and awards for the 2015-2016 school year.
• The Good Food Purchasing Program (GFPP) is presented as another viable reinvestment option. In the Los Angeles Unified School District, GFPP implementation since 2012 led to $12 million in purchasing being redirected to local sources and an increase in local fruit and vegetable purchases from 9% to 75% within two years.
