King County operates multiple facilities for the disposal or recycling of solid waste and household hazardous waste.
The Solid Waste Division (SWD) operates eight transfer stations and two drop boxes in King County. These facilities accept municipal solid waste from residents and businesses. Limited recycling services are available for residential customers.
The King County Solid Waste Division operates the Cedar Hills Regional Landfill, maintains several closed landfills, and contracts with a renewable energy company to generate renewable energy from landfill gas.
Small loads of C&D materials, in vehicles without tip beds, are accepted for disposal (not recycling/diversion) at King County transfer stations.
SWD operates one mobile and one fixed household hazardous waste facility. Residents can bring their leftover pesticides, batteries, thinners and solvents and other household hazardous wastes for proper disposal.
The major rules and regulations described here govern solid waste and are designed to maintain the highest standards of quality for human health and environmental protection.
