Schools across the United States discard roughly 40 percent of the food they serve, translating to an estimated 530,000 tons annually. That waste contributes significantly to environmental degradation, producing about 1.9 million metric tons of greenhouse gases each year, according to a recent report from the nonprofit World Wildlife Fund.
One elementary school in Georgia offers a glimpse of how this crisis can be tackled. At Lovin Elementary in Gwinnett County, students have helped cut food waste by 70 percent through hands-on education and practical interventions backed by organizations like World Wildlife Fund’s Food Waste Warriors program and local partners.
Starting With a Simple Audit
The initiative began in late 2018 with a straightforward food audit. Third and fifth graders lined up at two tables near the cafeteria exit, sorting through trays left behind by lunch-goers. They separated unopened items—milk cartons, bags of carrots and apples—from actual waste. The effort revealed that out of 589 pounds collected that day, 120 pounds were recoverable foods.
The findings shocked both students and staff. Teachers reported that unopened drinks and snacks were routinely tossed alongside spoiled food. Rather than assigning blame, the school turned to its youngest members for solutions. Students proposed simple ideas first, posters, morning announcements reminding peers they didn’t need to take milk if they wouldn’t drink it, and then moved toward more impactful changes.
One major innovation was introducing a share table: a designated spot where untouched meals could be redistributed. A refrigerated unit with a glass door allowed safe storage of items like sandwiches and fruit cups. Another idea involved using leftover produce from the teachers’ salad bar to feed newly acquired chickens in the school garden, an early step toward composting.
Program Expansion and Measurable Impact
Gerin Hennebaul, a STEM content specialist at Lovin Elementary, discussed the school’s collaboration with the World Wildlife Fund’s Food Waste Warriors program and local partners including Gwinnett Clean & Beautiful and its Green & Healthy Schools initiative. These organizations provided resources and guidance to help implement waste reduction strategies across campus.
The combined efforts resulted in a 70 percent reduction in food waste at Lovin Elementary. Each student became actively involved in diverting food from landfills and participating in composting activities. The program also supported academic learning, offering opportunities to practice math skills, engage in outdoor activities, and develop problem-solving and communication abilities.
From Composting to Curriculum
In fall 2021, Lovin Elementary secured a composting grant from the Food Well Alliance, which funded a new bin built specifically for the site. Though initially unfamiliar with the process, staff learned alongside students. By spring 2022, fifth graders had begun collecting scraps and studying decomposition. Within a year, all grades from first through fifth were involved.
Data collection became part of daily routines. Fourth graders weighed waste every afternoon, recording figures in binders to practice math skills including decimal addition. On Tuesdays, a master gardener worked with small groups to monitor compost temperatures, turning environmental science into real-world learning.
The program expanded beyond the cafeteria. Kindergarteners planted carrots each winter; third graders studied soil health using finished compost; and an eco-heroes club introduced younger learners to recycling principles. Older students even created songs and skits to teach concepts to kindergarteners, reinforcing lessons through peer instruction.
By the 2023–2024 school year, student-led efforts yielded 5,489 pounds of compostable material. Overflow led to partnerships with a nearby church that now transports food scraps twice weekly. Classroom vermicomposting bins added another layer of engagement, allowing year-round observation of organic breakdown processes.
Scaling Beyond Lovin Elementary
Expanding the program to other schools requires dedicated staffing and administrative backing. At Lovin, having a fully released teacher allows consistent oversight of composting and share table operations. Schools without similar support face difficulties maintaining daily routines and engaging students across all grade levels.
