Since 2012, Seattle City Council has directed new requirements to keep building materials out of landfills for construction jobs involving a Seattle building permit. The City’s building department (Department of Planning & Development) and solid waste utility (Seattle Public Utilities) have complementary procedures to increase salvaging, deconstruction, reuse, and recycling. Hundreds of projects have already complied with waste diversion planning and reporting during 2014, when these requirements took effect.
Wood without paint or preservatives joined the “Don’t Landfill” list as of January 2015. Already prohibited from landfilling and required to be recycled are: Scrap Metal; Cardboard; Asphalt Paving; Concrete; Brick; New Gypsum Wallboard.
