The Short Answer (and What to Do Instead)
Seattle Public Utilities (SPU) doesn’t accept expanded polystyrene (EPS) in the blue curbside cart. EPS is the technical name for what most people call Styrofoam. The reason it stays out is straightforward. Foam is roughly 95% air, breaks into tiny pieces that contaminate paper and cardboard, and isn’t economical to sort at standard recycling facilities.
Seattle gives you three free or near-free options to keep foam out of the landfill.
Option 1: Free Special Item Pickup from SPU
Seattle Public Utilities collects clean Styrofoam blocks and forms from your curb at no extra cost. Schedule online through your SPU account or call (206) 684-3000. On collection day, place your foam in clear or white bags next to your garbage cart. The service accepts blocks and forms only, with a two-bag (32-gallon) limit per pickup. It won’t take packing peanuts, foam sheets, or tan polyurethane.
Option 2: King County Transfer Stations
Two King County transfer stations accept clean white foam blocks at no charge: Bow Lake (in Tukwila) and Shoreline. If you’re already heading to one with other items, foam can ride along for free.
Option 3: Styro Recycle in Kent
About 30 minutes south of downtown Seattle, Styro Recycle runs a free public drop-off at 23418 68th Ave S in Kent. They accept block foam, packing peanuts (bagged separately), and clean cardboard, weekdays from 8 a.m. to 4:30 p.m. Their thermal densifier turns the foam into plastic that gets remade into picture frames, crown molding, and outlet covers.
Quick Rules Across the Board
Foam must be clean and dry, free of tape, labels, and food residue.
Food-stained foam (greasy takeout clamshells, for example) goes in your regular waste cart.
Tan or yellow polyurethane foam (couch cushions, mattress toppers) isn’t recyclable through these programs.
Washington banned the sale of EPS food containers, foam coolers, and packing peanuts under SB 5022. The ban has been in effect since June 2024, so you’ll see less foam arriving in your packages over time.
"On almost every Seattle job, someone asks us 'is Styrofoam recyclable?' before we've even started loading. After thousands of Pacific Northwest cleanouts, we've watched a single new TV or piece of flat-pack furniture fill half a truck with foam packaging alone. Clean white blocks recycle, but tan polyurethane, packing peanuts, and food-stained foam don't, so sorting before the haul saves time, money, and landfill space."

3 Statistics That Show Why This Matters
EPA: Of 80,000 tons of polystyrene containers generated in the U.S. in 2018, fewer than 5,000 tons made it to recycling. The rate sits effectively at zero. That’s why specialty programs like SPU’s pickup matter so much. Every block diverted is a block that wouldn’t have been recycled by default.
Source: U.S. Environmental Protection Agency. Frequent Questions about Materials, Waste and Recycling
Earth911: Americans send roughly 1,500 tons of polystyrene to landfills every single day, while less than 1% gets recycled. EPS is technically recyclable, but most communities lack the equipment and infrastructure to process it economically. That makes local programs like Seattle’s the exception, not the rule.

Cascade PBS: In 2020 alone, Seattle residents used SPU’s special foam pickup over 6,800 times, making it the city’s most popular special item collection. That signals Seattleites know foam doesn’t belong curbside, and they’re using the right channel. The system works. It just isn’t well-known enough.

Final Thoughts and Opinion
Foam recycling sits in a frustrating gray zone. Too valuable to landfill, too lightweight and easily contaminated for most curbside systems. Seattle has done more than most cities to bridge that gap, and Washington has done more than most states. Between SPU’s free pickup, the King County transfer stations, Styro Recycle in Kent, and the statewide ban on the worst single-use foam products, residents have solid options.
Here’s our honest take, drawn from years of clearing Pacific Northwest homes. Seattle’s system works. The catch is that few residents know it exists. Most people we work with assume foam is either landfill-only or curbside-friendly, and neither is true. A few minutes of sorting and one phone call (or one trip to Kent) keeps a striking amount of foam out of the landfill.
For a piece or two from holiday gifts or new appliances, schedule SPU’s free pickup. It’s one of the better deals in Seattle city services. For the kind of foam mountain that comes with a move, remodel, or full estate cleanout, it’s usually faster (and far less back-breaking) to bring in a full-service team that already knows where every load goes. Smart project planning also means right disposal timing, so foam, old furniture, and packaging don’t pile up for weeks while you decide what to do.
While you’re refreshing your space, a deeper home reset often makes sense. Many homeowners pair their cleanouts with ductwork care basics and air filter basics, so the spaces they’ve just cleared end up cleaner and fresher, not just emptier.
Frequently Asked Questions
Why can’t Styrofoam go in my Seattle curbside recycling cart?
Foam is roughly 95% air, which makes it expensive to transport and easy to break apart. Tiny foam pieces contaminate other recyclables like paper and cardboard, lowering the value of the entire load. That’s why Seattle’s curbside program excludes it and routes foam to specialty pickup and drop-off programs instead.
What kinds of foam does Seattle’s pickup service accept?
Only expanded polystyrene (EPS) blocks and forms. That’s the kind of foam used to pack TVs, appliances, and furniture. Special Item Pickup won’t accept packing peanuts, foam sheets, polyurethane (typically tan or yellow), or food-contaminated foam.
Can I take Styrofoam to a Seattle transfer station?
For drop-off, use the King County stations: Bow Lake (in Tukwila) or Shoreline. Both accept clean white foam blocks at no cost. Call ahead to confirm hours and any current restrictions.
Is there a fee for SPU’s foam pickup?
No. The Special Item Pickup service is free for foam blocks and forms. You’ll need a Seattle Public Utilities account to schedule it, and the pickup happens on your normal garbage day after you receive confirmation.
Are packing peanuts banned in Washington?
Yes. Washington banned the sale and distribution of EPS packing peanuts statewide in June 2023 under SB 5022. You can still recycle peanuts you already own at Styro Recycle in Kent, or donate them to a local shipping store for reuse.
What if foam shows up during an attic or basement cleanout?
That’s one of the most common scenarios. Old packaging from appliances, electronics, and seasonal decor stacks up over years. Our attic cleanout guide walks through the full sorting process. The short version: separate clean white EPS blocks from food-stained foam and tan polyurethane, bag everything appropriately, and route it to the right facility. Skip the curbside cart.
Do I need to break the foam into smaller pieces?
Big pieces are fine. They just need to fit the bag and weight limits for whichever program you’re using. For SPU pickup, foam goes in clear or white bags up to 32 gallons each. Avoid crumbling foam into small pieces. Crumbled foam is harder to handle and can contaminate the load.
What if I have a huge pile from a move or remodel?
That’s a job for a full-service junk removal team. Jiffy Junk handles foam-heavy cleanouts across Seattle. Our crews sort recyclable blocks from non-recyclable foam on site and route everything to the right facility, so you don’t make multiple trips.
