Organics collection

Learn effective strategies for composting food scraps and reducing contamination.

Food scraps, partially eaten, and unwanted food that can't be donated can be collected for composting. A new law starting on January 1, 2025 will require schools to compost food waste if they create more than 1 cubic yard per week. That's about the size of a refrigerator. The Green Schools Program provides guidance, indoor collection bins, signs, and educational tools. Contact your program representative to learn more about how your school may be impacted by the Organics Management Law.

Criteria for recognition

Schools

  • Establish and maintain organics collection and sustain low or no contamination in the organics bins for at least 3 months.
  • Create a system to monitor contamination in organics bins. Collect data over time (at least 2 weeks) to see how effective your system is. Share results with your program representative. Conduct a baseline Waste Walk Through (WWT) at least every 2 years. Use the information to set organics collection goals.
  • Share organics collection goals with the rest of the school. Examples could include assemblies, newsletters, announcements, or social media posts.
  • Provide labeled organics collection bins paired with a trash can in kitchens, cafeterias, or areas where food is prepared or consumed. See our resources below for examples of bins and labels.
  • Share your organics collection efforts and progress with your program representative

Success stories

Pacific Cascade Middle School in Issaquah School District also initiated school composting at both A and B lunches. Their goal was to educate the student population on why and how to compost food waste. To do this, the Green Team made posters for the hallways and created Kahoot games to play in homeroom to teach students what goes in the organics bin. Over 50 students volunteered to monitor lunch cleanup and teach others how to sort. The school estimates that they saved an average of 77lbs of food waste from going into the landfill every single day.

John Muir Elementary School in Lake Washington School District started collecting food scraps from their cafeteria this year! They made a PowerPoint presentation to provide education to students and staff about how to go through the lunch waste food sorting line. They organized monthly trainings with student volunteers from 3rd, 4th, and 5th grades that monitored the food waste line at the three lunch periods. Students also learned that their food scraps from the cafeteria will be made into compost. At our Earth Day seed planting event, the students used Cedar Grove compost and saw first-hand what their food waste would become.

Students from John Muir Elementary use compost to plant seeds for Earth Day. They learned that the food scrap program they started this year will turn into compost.
