Our vision and mission
At the Solid Waste Division, our vision is to lead a self-sustaining and resource recovery system, eliminating the need to landfill and safeguarding the environment for our communities. Our mission is to responsibly manage and prevent waste in service of King County, through our strong partnerships and the efforts of our united workforce.
We provide efficient collection of solid waste, recyclables, and organics, while protecting public health and the environment, promoting equitable service, and maximizing waste diversion.
Our waste transfer system
We operate 8 transfer stations, 2 rural drop boxes, and the Cedar Hills Regional Landfill – the only operational landfill in the county. We also maintain custodial responsibility for 9 closed landfills.
Our solid waste system ensures that unincorporated King County and 37 cities have access to safe, efficient garbage transfer and disposal, and recycling services. We serve all cities in the county except for Seattle and Milton, which are part of separate solid waste systems.
Working towards a more sustainable, equitable future
Almost 70 percent of the stuff sent to the Cedar Hills Regional Landfill each year could have been recycled. A major shift is needed to create a regional solid waste system that’s better for both the environment and our communities. Re+ is King County’s approach to creating a system that prioritizes waste reduction and prevention while centering community needs. Through Re+, we’re reducing climate impacts, conserving resources, and working with our city partners and community members to create a more equitable waste-free King County.

Our values
We're guided by King County's ACTIVATE values, which are the shared expectations for the way we act, make decisions, and deliver change for the people of King County.
ACTIVATE stands for: Accountable, Collaborative, Timely, Impactful, Value Employees, Accessible, Trusted, and Equitable.

Equity, Racial and Social Justice program
In 2010, Executive Dow Constantine signed an ordinance that requires the principles of equity, racial and social justice (ERSJ) to be included in all strategic planning, comprehensive planning and policy decisions at King County. These principles were defined in the King County Equity and Social Justice Strategic Plan.
SWD works to actively apply an equity lens in all our lines of business to advance the goals of the ESRJ Strategic Plan.
Climate action
We’re committed to reducing waste and greenhouse gas emissions from our solid waste system. Our work is guided by climate goals outlined in King County’s Strategic Climate Action Plan and the King County-Cities Climate Collaboration agreements.
