Is Styrofoam Recyclable? A Guide for Companies.
Styrofoam is recyclable, but in practice most of it is not recycled. Clean foam packaging from a business can go to a recycler. Foam cups and takeout containers usually end up in a landfill, and in California most foam foodware can no longer be sold at all.
If your company ships, receives or destroys product, the answer depends on what kind of foam you have, how clean it is and how much of it you generate. Here is what businesses need to know about recycling styrofoam.
What Styrofoam actually is
“Styrofoam” is a brand name. What most people mean is expanded polystyrene, or EPS: polystyrene plastic (resin code #6) puffed into beads that are about 98% air.
There are a few kinds of foam, and recyclers treat them differently:
- EPS has a beaded look. It is used for packing blocks, coolers and many foam cups.
- Extruded polystyrene (XPS) is smoother. It shows up in meat trays, egg cartons and building insulation.
- Rigid polystyrene (GPPS or HIPS) is not foam at all. It is used in disposable cutlery and appliance parts.
All three are polystyrene, but they need different recycling methods. Earth911
Why most curbside programs won’t take it
The problem with foam is economics, not chemistry. Polystyrene is easy to reprocess, but foam is so light that collecting and hauling it costs more than the material is worth.
- It’s mostly air. A full 53-foot trailer of loose foam weighs about 2,000 lbs. The same trailer of densified foam can carry a normal 40,000 lb load. Packaging Digest
- Food contamination. Grease and food residue on cups and clamshells make them worthless to most buyers.
- It breaks apart. Foam crumbles in sorting equipment and blows around facilities.
As a result, most curbside programs don’t accept foam, and households have even fewer options for it than for other plastics. Earth911
California has already banned most foam foodware
Under SB 54, California’s packaging producer responsibility law, foam foodware producers had to show a 25% recycling rate by January 1, 2025. They didn’t meet it, so the sale, distribution and import of EPS foodware is now banned in the state. CalRecycle notice
- What’s covered: single-use trays, plates, bowls, clamshells, cups and lidded containers.
- Who’s responsible: “producers” broadly, including manufacturers, brand owners, importers and distributors that bring foam foodware into California. Morgan Lewis
- Penalties: up to $50,000 per day per violation. The Attorney General issued an enforcement advisory in December 2025 because foam foodware was still being sold. California AG
The ban covers foodware, not foam used as protective or transport packaging. That foam is still common, and it is the type with a real recycling market. CalRecycle’s permanent SB 54 regulations took effect May 1, 2026, with full program implementation scheduled for January 1, 2027. Resource Recycling
How businesses can recycle foam packaging
Clean foam from shipping and transport packaging is where recycling works. EPS transport packaging has a verified recycling rate of 31% in North America, and the industry has identified 81 companies running 119 facilities that handle foam. Packaging Dive
Most of that volume comes from businesses, not households.
To make your foam recyclable:
- Keep it clean and separate. Pull foam out of the trash and cardboard streams. Remove tape, labels, cardboard and anything with food on it.
- Sort by type. Keep white EPS packing blocks apart from colored foam, XPS trays and rigid plastics.
- Densify it. A densifier compresses foam up to 90 to 1, turning a trailer of air into dense blocks that are economical to ship to a reclaimer. Densified EPS is made into new packaging, insulation and molded products. Resource Recycling
- Work with a recycler who has an outlet. Smaller volumes can go to one of the 400+ drop-off sites on the EPS Industry Alliance map. Regular, large volumes are better handled through a recycling partner on a scheduled pickup. Waste Today
Distribution centers, electronics and appliance companies, medical suppliers and anyone running large depackaging or product destruction jobs tend to generate enough clean foam to make this worthwhile.
Use less foam to begin with
The cheapest foam to handle is foam you never receive. More companies are moving away from EPS for transport and protective packaging, and more bans are likely as packaging producer responsibility laws spread to other states.
- Molded pulp or corrugated inserts can replace foam blocks for many products, and they go out with your OCC.
- Ask suppliers about take-back for foam packaging on inbound shipments.
- Track your volume. Knowing how much foam comes through your dock each month tells you whether a densifier or a scheduled pickup makes financial sense.
