Reminder: Construction-demolition debris now directed to expanded recycling network


As of Nov. 1, large quantities of construction and demolition waste (C&D) will no longer be accepted for disposal at King County solid waste facilities. Instead, these materials should be taken to a C&D handling facility and put back into the economy as recycled or repurposed materials, or disposed.


As part of its commitment to reduce waste and increase recycling, King County is no longer accepting large quantities of construction and demolition (C&D) materials as garbage at its solid waste facilities beginning Nov. 1.

This includes C&D waste in dump trucks or other mechanized dump vehicles, and also in mechanized (hydraulic and hand-cranked) dump trailers.

“More than 250,000 tons of construction and demolition debris generated in King County go to landfills as waste every year – and a significant portion of that can be recycled or reused,” said Christie True, director of the King County Department of Natural Resources and Parks. “Diverting recyclable and reusable materials from landfills is in line with our region’s strong stewardship ethic.”

Small quantities of C&D waste brought in vehicles or trailers without mechanized dump beds, and C&D materials mixed with larger loads of garbage that don’t exceed roughly 10 percent of the total load will still be accepted at King County-operated transfer stations.

C&D materials generated during the construction and demolition of buildings, roads, and other structures that can be recycled includes clean wood, cardboard, metal, new gypsum scrap, asphalt paving, bricks and concrete. C&D waste includes materials such as roofing, painted wood, insulation and cement siding.

King County will continue to direct customers with C&D recyclable materials and C&D waste to privately-owned C&D handling facilities that are routinely monitored to ensure compliance with environmental standards.

For an updated list of facilities authorized to accept C&D materials for recycling or disposal, visit or call the Solid Waste Division at 206-477-4466.

A King County ordinance requiring increased recycling rates of C&D materials was passed in 2015. This ordinance is in line with the goals of King County’s Strategic Climate Action Plan (SCAP) by reducing greenhouse gas emissions through recycling and reusing construction materials, rather than manufacturing new materials.

The SCAP also outlines King County’s goal to recover and recycle 70 percent of waste materials by 2020.

Currently King County residents and businesses recycle 54 percent of all solid waste generated.
