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 itemslinks to external site or uncoated paper products like Chinet. Coffee cups like you get at Starbucks are recyclable, not compostable.
