Styrofoam 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 Styrofoam at special collection locations to be recycled. Styrofoam can also be disposed in your regular garbage can at home.
Both styrofoam and plastic bags are accepted at this special collection event hosted by the City of Kirkland. We also accept flexible styrofoam (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 2019 dates (PDF, 267kb) for details. The event is open to Kirkland residents only due to costs and capacity constraints.
If you only have a very small quantity of Styrofoam, 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.
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 Styrofoam recycling at our Spring and Fall Recycling Collection Events, typically held in May and October.
StyroFest is the only option for recycling styrofoam in Kirkland. Can't make it to StyroFest? Here are more styrofoam recycling options (pdf, updated 2018) in the Seattle area, including Bothell, Issaquah, Kent, Shoreline and Seattle SoDo. Please call before you make a special trip to confirm they will accept your material.
