Food + Yard

compost poster no yard waste

What can I put in my gray cart?
All compostable items should go in your gray cart. You can compost:
Compost Cart
  • Food scraps (including meat, bones, shells, and dairy)
  • Food-soiled paper like pizza boxes and paper napkins
  • Yard trimmings
  • Shredded paper (layer with yard waste or put in a paper bag)

Download the complete guide (pdf, 2mb).

Help Make Good Compost
  • NO plastic bags in your gray bin! If you want to bag your food scraps, use compostable bags like BioBags or paper bags. See accepted bagslinks to external site.
  • Absolutely NO pet waste or diapers.
  • Pick the stickers off your produce, and untwist the wire or rubber bands from your carrots and kale. Produce stickers and ties are trash.
  • Use approved compostable plates, cups, and cutlery at get-togethers – Cedar Grove branded items or uncoated paper products like Chinet. Coffee cups like you get at Starbucks are recyclable, not compostable.
  • Take your yard waste cart to the curb for pickup every week, not just when it’s full.

What happens to my food and yard waste?
All your food and yard waste goes to Cedar Grove composting facilities in Everett or Maple Valley, where it's turned into compost in a matter of weeks. The average household's food scraps and yard trimmings produce five yards of compost each year, according to Cedar Grove.
