Short answer
Polystyrene is technically recyclable but rarely accepted at kerbside in 2026. Both forms (rigid polystyrene marked PS or recycling code 6, and expanded polystyrene known as EPS or Styrofoam) cause problems for standard recycling facilities. Most UK and US councils refuse it in household bins.
The two forms behave differently:
- Rigid polystyrene (PS / code 6): yoghurt pots, plastic cutlery, CD cases, takeaway containers. Hard plastic. Can theoretically be melted and reformed, but most facilities reject it because mixed-plastic contamination is severe.
- Expanded polystyrene (EPS): white foam packaging, fish boxes, building insulation. 95% air, 5% plastic by volume. Shatters into beads that jam sorting machinery.
UK kerbside acceptance rates 2026
According to WRAP UK and local authority surveys updated April 2026:
| Council type | Accepts rigid PS in kerbside | Accepts EPS in kerbside |
|---|
| Most London boroughs | No | No |
| Manchester, Birmingham, Leeds | No | No |
| Edinburgh, Glasgow | No | No |
| Cornwall (mixed-plastic streams) | Partial | No |
| Northern Ireland councils | No | No |
| Rural Welsh authorities | Mostly no | No |
Roughly 3% of UK councils accept rigid polystyrene in kerbside recycling as of 2026. Expanded polystyrene is accepted by under 1% (Material Focus 2024 audit).
US kerbside acceptance rates 2026
The US picture varies by state and city:
- California: SB 54 (Plastic Pollution Producer Responsibility Act) is phasing out single-use polystyrene foam in food service from 2025 onward. Kerbside acceptance remains limited.
- New York City: banned EPS food containers since 2019. Kerbside recycling rejects both PS and EPS.
- Maryland: statewide EPS food packaging ban since 2020.
- Most US municipalities: refuse both forms in kerbside recycling.
- Drop-off-only programs: some Whole Foods locations and IKEA stores accept EPS shipping packaging at customer service desks. Limited and inconsistent.
Where polystyrene can actually be recycled
Practical disposal routes for both forms:
- Manufacturer take-back programmes: some white-goods retailers (Currys, John Lewis) accept EPS packaging when delivering new appliances. The driver typically takes back the foam at delivery time.
- EPS recycling specialists: in the UK, Streamline Recycling, Recoup, and a small number of local authorities operate drop-off banks specifically for clean EPS.
- Construction sites: large quantities of clean EPS insulation can be returned to manufacturers like Kingspan or Knauf Insulation through specifier-led take-back programmes.
- Plastic Bank programmes: emerging in major cities, accept rigid polystyrene at consolidation points.
Most household quantities, realistically, end up in residual waste (landfill or energy from waste).
Why polystyrene is so hard to recycle
The technical barriers explain the low acceptance rate:
- EPS is 95% air: collection vehicles fill rapidly with low-weight material, making collection uneconomic.
- Contamination: food residue and packing tape on EPS are difficult to remove. Cross-contaminated batches are rejected at processing.
- Polymer mixing: PS often contains additives like flame retardants or pigments that prevent clean melt-and-reform processing.
- End-market collapse: China's National Sword policy (2018) eliminated the largest export market for recycled polystyrene, leaving few buyers.
What to do with polystyrene packaging at home
If you've just received an Amazon delivery, a TV, or a flat-pack with polystyrene packaging:
- Reuse for future moves or storage: clean EPS is excellent shock protection
- Offer on Olio, Freecycle, or local community boards: artists, hobbyists, and house-movers value clean EPS
- Drop at a participating retailer: confirm acceptance before driving
- Last resort: residual waste bin. Confirms WEEE-style "recycling responsibly when possible" outcome rather than ocean pollution.
What polystyrene becomes when it IS recycled
When clean rigid polystyrene reaches a specialist facility, the recycling path is:
- Granulation into flakes
- Washing and decontamination
- Re-melting at 240-260C
- Extrusion into pellets
- Reformulation into products: picture frames, plant pot trays, garden furniture, audio CD cases
EPS recycling produces denser PS that can be used for similar applications, plus insulation board components.
Best practice
Reduce polystyrene consumption first (refuse, return to vendor, request paper packaging where available). Recycling is the worst environmental option per the waste hierarchy. Avoid polystyrene-packaged products where reasonable alternatives exist.
Key takeaways
- Polystyrene is recyclable in theory but accepted in under 5% of UK and US kerbside programmes
- Rigid PS (code 6) is more accepted than expanded EPS (Styrofoam)
- Best disposal routes: manufacturer take-back, EPS specialist drop-offs, retailer schemes
- Most household quantities realistically end up in residual waste
- Reducing polystyrene consumption beats recycling on every environmental measure

Frequently Asked Questions
Can I put polystyrene in my recycling bin?
Generally no. Roughly 3% of UK councils accept rigid polystyrene (code 6) in kerbside recycling, and under 1% accept expanded polystyrene (EPS or Styrofoam). Check your local council's accepted-items list before placing any polystyrene in recycling.
Where can I recycle polystyrene packaging?
Some white-goods retailers (Currys, John Lewis, IKEA) take back EPS packaging at delivery. EPS-specific drop-off banks exist in a small number of UK areas via Streamline Recycling and Recoup. For US residents, some Whole Foods locations accept clean EPS at customer service.
Why don't councils accept polystyrene?
Three reasons: collection vehicles fill with low-weight EPS uneconomically (95% of the volume is air), contamination from food residue is hard to remove, and the recycled-polystyrene end-market collapsed after China's 2018 National Sword policy. The economics don't support kerbside collection.
Is there any difference between rigid polystyrene and Styrofoam?
Yes. Rigid polystyrene (PS, code 6) is hard plastic used in yoghurt pots, CD cases, plastic cutlery. Styrofoam is one brand of expanded polystyrene (EPS), a foam used in shipping packaging and insulation. EPS is much harder to recycle because of its high air content.
What's the best thing to do with Styrofoam packaging from a delivery?
Reuse it for future shipping or storage. Offer it on local Freecycle or Olio groups (artists and house-movers value clean EPS). Drop at a participating retailer if one is nearby. Last resort: residual waste. Reducing polystyrene consumption by refusing or requesting paper packaging is environmentally better than any recycling option.
