What is it?

Wood such as clean timber, dimensional lumber, stumps and limbs are readily recyclable. Wood that has been treated (with creosote, for example), painted, stained or contaminated is not appropriate for recycling and should be properly disposed of.

Why recycle wood?

In the landfill wood is a wasted resource. Wood can be reused as building material, recycled into mulch for landscaping or pulp for paper production and used beneficially as a fuel. Reusing and recycling wood reduces the need to cut down trees.

Eighty percent of materials thrown away are resources – not waste.

What can you do?

  • Recycle waste wood. Use King County's What do I do with…? website to find facilities that accept wood for recycling or reuse.
  • Consider chipping wood debris for landscape cover. Wood chips make excellent mulch for garden beds. A number of companies chip wood from trimmed or downed trees, including some tree services.
  • Buy and use salvaged or recycled wood and wood products or non–wood materials that are more easily recycled. If you use wood, choose certified wood, which means that the trees are harvested from a sustainably managed forest. To learn more see the Forest Stewardship Council external link website.
