All your compostables should go in your gray cart.

Why should I compost and where does it all go?

Compost to save money and help the planet. By taking the time to put compostables in your gray cart, you generate less trash. With less trash, your complex can opt for a smaller (and cheaper) garbage service level.

Composting helps the environment by keeping food out of the landfill and turning it into a soil enhancer. Food that goes to the landfill does not decompose due to the low-oxygen environment; it breaks down very slowly in a process that emits methane, a powerful greenhouse gas.

All compostable items in your gray cart go to Cedar Grove's composting facility in Everett.

What can I put in my gray cart?

Compost Cart

Food scraps, food-soiled paper, biodegradable bags/liners, and yard trimmings go in your gray cart. Download the complete guide (PDF - 2.1MB). You can get a free sample of BioBags at Kirkland City Hall at the Public Works counter; you can also get a free reusable food scrap countertop pail at the City Hall Recycling Center.

How do I start compost service at our complex?

Compost service is available to all qualified apartment and condominium complexes. To sign up, get approval from your property manager or homeowners' association and complete the online application.

Want to compost but it won't work at your complex? The City is offering a pilot food scrap drop-off program that will allow people who live in condos and apartments to compost at City Hall. Get details about how to participate.
