In October 2023, Bronx River High School launched ‘Green Canteens,’ a student-led composting project that has cut cafeteria food waste by nearly half. The program is now inspiring other Bronx schools to follow suit.

Bronx River High School, tucked beside the lush Bronx River, has become a proving ground for one of New York City’s most ambitious school-based sustainability efforts. As lunch trays clatter in the bustling cafeteria, students in green aprons assist peers in sorting scraps for composting—a daily ritual that, since October 2023, has transformed what would be landfill-bound refuse into nutrient-rich soil.

The driving force behind this change is a coalition of students, science teacher Maria Castillo, and the Bronx Green Action Council. Their ‘Green Canteens’ project began as a response to alarming Department of Sanitation reports: New York City public schools generate more than 80,000 tons of food waste annually. By integrating hands-on environmental science with cafeteria operations, the initiative has educated over 600 students and yielded measurable reductions in waste.

The program’s impact is already visible. Bronx River High School now diverts nearly 500 pounds of food scraps each month to local composting facilities, including the city-run curbside composting program and Bronx River Alliance gardens. Students say participation has fostered a new sense of responsibility and pride, especially as neighboring schools—like PS 211 and Lehman High—begin to emulate the model.

City officials have taken notice. The NYC Department of Education is evaluating the pilot for potential expansion across all five boroughs, aiming for 2025 implementation. As New York advances toward its zero-waste goals, Bronx River High School’s student-led canteens offer a glimpse into a greener future, forged one lunch period at a time.
