Tips & Guidelines

Compostable material includes food scraps and yard waste. Carnation residents can subscribe to weekly compost collection for a low monthly fee. The handling and processing of compostable material is less resource-intensive than processing garbage and creates a valuable product to use in parks and gardens. Approximately 30% of all material that ends up in the landfill could be composted instead. When you keep food scraps, food-soiled paper and yard debris separate from your garbage, you extend the life of our landfills and conserve resources.

Your compost cart is collected weekly along with your garbage and recycling. To sign up for service call Recology CleanScapes at 425.837.1234.
