Solid Waste Management Planning

The City of Seattle is required to develop a comprehensive solid waste management plan and update it every six years. Seattle Public Utilities (SPU) prepares the plan, which provides a roadmap for how the City will manage and finance its solid waste services and facilities over the next 6 years, and projects system management needs over 20 years. The plan describes how Seattle handles, collects, processes, and disposes of Seattle's waste, progress toward solid waste goals, and waste prevention, recycling, and composting programs and policies.

On April 11, 2023, the City Council adopted the Seattle’s latest comprehensive solid waste management plan, 2022 Solid Waste Plan Update: Moving Upstream to Zero Waste (2022 Plan Update). The Washington State Department of Ecology approved the 2022 Plan Update on June 7, 2023.
