State Solid Waste Management Plan

The State Solid Waste Management Plan guides the management of waste and materials in Washington and aids local governments as they develop local solid waste management plans. This plan advances the state's waste management hierarchy, established in the solid waste statutes; that waste reduction is the highest priority, followed by recycling, energy recovery, and then safe disposal (RCW 70A.205.005).  

The State Solid Waste Management Plan promotes a sustainable materials management approach. This method looks at the full life cycle of materials through multiple phases, from the design and manufacturing, through use, and finally to the end-of-life phase when the material is either reused, recycled, or disposed.

State plan split into two separate plans

The last plan was combined with the State Hazardous Waste Management Plan and was published in 2021 as the State Solid and Hazardous Waste Plan. We have updated this plan several times over the decades. This next update will result in two separate plans: one for solid waste and one for hazardous waste.
