Reducing Food Waste, Growing Sustainability

Lessons from the Rhode Island School Recycling Project

Abstract

Food waste offers a powerful, real-world context for advancing K-12 science learning while addressing urgent environmental and equity challenges. This paper examines how food-waste reduction can serve as an anchoring phenomenon aligned with NGSS science and engineering practices, including data analysis, systems thinking, and solution design. Drawing on the Rhode Island School Recycling Project (RISRP), a statewide initiative launched in 2001 and expanded to address organics diversion and food recovery, we describe a two-year, whole-school model that integrates cafeteria routines with classroom instruction. RISRP’s Get Food Smart program engages students, teachers, administrators, custodial staff, and food service workers in coordinated efforts to reduce, recover, and recycle food waste. Central to the model are student-led waste audits, share tables, composting systems, and data dashboards that position the cafeteria as a living laboratory for authentic scientific inquiry. Program outcomes from participating schools demonstrate measurable reductions in landfill waste, recovery of edible surplus food, and increased student leadership and engagement. We outline stakeholder roles, assessment practices, implementation challenges, safety considerations, and adaptable strategies for diverse educational contexts, including teacher preparation programs. By linking climate mitigation, food insecurity, and science instruction, RISRP illustrates how sustainability education can be embedded into everyday school practices without requiring extensive resources. Food-waste reduction emerges not as an environmental add-on, but as a practical, standards-aligned pathway for cultivating student agency and community resilience.
