• Food Waste (Organics)

    Since August 2019, all school kitchens (Back of House) have been collecting food scraps to help reduce our environmental impact and landfill-bound waste.


    For more information on starting a Student Food Waste Collection Programs (Front of House) in the cafeteria, see here!



    Why do we collect food waste?

    40% of food produced in the U.S. goes to waste. Food waste is one of the largest greenhouse gas emitters because it releases a gas called methane that is 30 times more potent than carbon dioxide.


    What types of materials do we collect in the food waste?

    • Fruits and veggies
    • Grains (bread, rice, etc.)
    • Meat (chicken, fish, beef, etc.)
    • Dairy (cheese, yogurt, eggs – no liquids, i.e. milk)
    • Bones, egg shells
    • Leftovers, scraps
    • Spoiled food


    Why is this different than composting at home?

    Because PPS is considered a commercial business, it must adhere to Metro’s commercial food waste regulations. This means that we can only accept food. The food waste from commercial businesses IS NOT composted alongside residential compost. Residential compost goes to Recology in North Plains to be composted. It is important that the food waste is not contaminated with things such as napkins, wrappers, plastic utensils, etc. If you put it in your mouth to eat, then it can go in the food waste.


    What happens to the food waste?

    Our food waste is collected and hauled to Metro Central Transfer Station. From there, Mero determines three different facilities to send the food scraps:

    1. Recycology's NW Greenlands facility in Aumsville
    2. Shell New Energies anaerobic digester in Junction City
    3. Pacific Region Composting in Corvallis
