The Western Wood Preservers Institute is a non profit trade association based in Vancouver, Washington, that has represented the preserved wood products industry in western North America for more than 75 years. Its members are involved in manufacturing treated wood products or are affiliated with services related to the preserved wood sector, including production of pressure treated lumber, timbers, poles, posts, piling, and utility components. The organization focuses on regulatory and market outreach activities to support a viable regional industry and provides training to professionals in construction, architecture, and electrical utilities to support appropriate use and understanding of preserved wood products. WWPI operates within the paper and forest products manufacturing sector and offers educational programs and standards seminars to relevant industry participants. A notable recent development is the launch of the TWWDisposal.org website in mid-2025, which provides information on disposal and links to landfills that accept treated wood waste. Based in the Pacific Northwest, WWPI serves its regional market through activities that align with its mission of sustaining the preserved wood products industry.
