As of January 2014 all construction and demolition projects in Seattle will need to keep the following material out of disposal containers and transfer station disposal areas: metal, cardboard, and new construction gypsum scrap materials. Asphalt paving, bricks, and concrete are already banned from disposal. The expanded disposal ban will not apply to other targeted recyclable materials such as carpet, plastic film wrap, clean wood, and tear-off asphalt shingles until 2015.
