Seattle residents can compost trees and greens free of charge between December 26, 2011 and January 9, 2012.
At Recycling & Disposal Stations
Trees should not exceed eight feet in length and must be free of decoration so they can be turned into compost for local parks and gardens. Trunks should not exceed four inches in diameter. The stations will accept up to three trees per vehicle for free. Find station locations and hours here.
At the Curb
Food and yard waste subscribers can put trees and greens out on their regular collection day. Cut trees into sections, six feet long or shorter, with branches trimmed to less than four feet to fit into the collection trucks. Bundle each section with sisal string or twine (not plastic). Decorated, flocked and plastic trees are not recyclable, and will be charged as extra garbage.
Multi-family buildings can put out one tree next to each food and yard waste cart at no extra charge each collection day.
