StyrofoamTM cannot be recycled in your curbside recycling containers because it breaks apart at the Recycling Center, is not feasible to sort, and so lightweight that a very large volume must be collected to produce a saleable quantity of material. You can drop off StyrofoamTM at special collection locations to be recycled. StyrofoamTM can also be disposed in your regular garbage can at home.
Both StyrofoamTM and plastic bags are accepted at this special collection event hosted by the City of Kirkland. We also accept flexible plastic foam (EPE). Materials must be clean, dry and empty, and should be sorted by type and color. Please remove packing tape and labels. Packing peanuts are not accepted at StyroFest, and should be thrown away.
See the StyroFest guidelines and 2020 dates (PDF, 327kb) for additional details. The event is open to Kirkland residents only due to capacity constraints and increasing costs of hosting the events. Only one vendor in the Seattle area recycles foam and they are at maximum capacity, so we are not able to add more events.
The event is very busy, so we ask that you prepare the material you're bringing in advance:
- Remove packing tape
- Remove labels
- Sort material by color and type
We also offer StyrofoamTM recycling at our Spring and Fall Recycling Collection Events, typically held in May and October.
If you only have a small quantity of material to recycle, we encourage you not to make a special trip but to save it until you have more material or to combine with nearby errands, to maximize the environmental benefit of drop-off recycling.
StyroFest is the only option for recycling StyrofoamTM in Kirkland; Styrofoam is not accepted in your recycling cart at home. Drop-off recycling is available in Kent and Shoreline. Residents of neighboring cities may have access to local foam recycling options. StyrofoamTM can be disposed as trash in your regular garbage can at home, or large quantities can be thrown away at the Houghton Transfer Station in Kirkland for a fee.
