Yard and Food Waste Collection

WM NorthwestComposting your yard and food waste helps to reduce greenhouse gas emissions, improve soil quality, reduce the need for chemicals and fertilizers and save water.

Collection Schedule


Yard / food waste collection is provided at no extra cost with your basic garbage service. Customers receive collection every other week on garbage day. Food scraps and food-soiled paper go only in the Food/Yard cart provided by WM. Food scraps are not accepted in any other containers.

Food Scraps Accepted in Yard Carts:


Collect kitchen food scraps in containers such as:


Kraft type yard bags

Extra Yard Trimmings


There is a charge for additional units of yard trimmings (no food scraps) beyond the basic service.

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.
