Cart Tagging


City of Kirkland and WM use "Compost Only" Oops tags to monitor contamination in food/yard waste carts. If a driver spots contamination in your food/yard waste cart, the cart will be tagged, and you will be informed on proper disposal. Food/yard waste carts should be free of contaminants prior to servicing.

Extra Yard Trimmings


For yard trimmings that don't fit in your yard cart you may use:

  • Paper yard bags (available at home and garden stores), or
  • 32-gal. cans with handles & lids (65 lb. limit) labeled "Yard" or
  • Bundles tied with sisal twine (4'x2' limit)

    * Yard trimmings are not accepted in plastic bags.

    Plastic bags are not compostable and cause processing and odor problems at the composting facility.

    Put yard trimmings in a yard cart to be collected at the curb
    ------ (Sign up for food / yard collection.)
    Take yard trimmings to a transfer station that accepts "clean green".
