Can You Recycle Polystyrene in the UK?

In most parts of the UK, polystyrene is not accepted in household recycling bins. This includes both expanded polystyrene (EPS) — the white, foam-like material used in packaging — and regular polystyrene used in some takeaway containers and insulation materials.

Although technically recyclable, polystyrene is difficult and costly to process, which is why most local councils ask that you put it in your general waste bin.


What Is Polystyrene?

Polystyrene is a type of plastic (plastic number 6) that comes in two main forms:

  1. Expanded polystyrene (EPS) – Lightweight, white, and foamy. Commonly used in packaging for electronics, appliances, and takeaway food.

  2. Solid polystyrene – More rigid and used for items like CD cases, disposable cutlery, and some food trays.

Both types pose environmental issues because they don’t biodegrade and break into microplastics, which are harmful to wildlife and ecosystems.


Why Isn’t Polystyrene Recycled Curbside?


There are several reasons:

  • Low recycling value – It’s mostly air (about 98%), making it inefficient to transport and recycle.

  • Contamination risk – Takeaway boxes and food trays are often greasy or dirty, which makes them unsuitable for recycling.

  • Lack of facilities – Only a few specialist recycling centres in the UK can process polystyrene, and it's not widely accessible.

Because of this, most councils won’t accept it in your recycling bin — even if it’s clean.


What Should You Do with Polystyrene?

1. Check with Your Local Council

Some areas may have specific drop-off points for clean EPS (such as at recycling centres), though it’s rare. Visit your council’s website or use the Recyclenow locator to check what’s accepted in your area.


2. Reuse Where Possible

Clean polystyrene can be reused for:

  • Packaging fragile items

  • DIY or insulation projects

  • Crafts or school projects

While it’s not ideal, reusing is better than sending it straight to landfill.


3. Put It in Your General Waste

If no local recycling options exist, place it in your black bin (non-recyclable waste). Break it into smaller pieces to save space.


Can You Recycle Polystyrene in the UK Anywhere?

Yes — but only through specialist recycling services, usually available to businesses or through private recycling companies. Some companies accept large volumes of clean EPS for commercial recycling, where it’s compacted and turned into new plastic products.

For most households, though, access is very limited.


Final Thought

While polystyrene is technically recyclable, most UK households cannot recycle it through kerbside collections. If you’ve got a small amount, your best option is to reuse it or dispose of it in your general waste. To reduce waste long-term, consider avoiding products packaged in polystyrene and opt for more eco-friendly alternatives.
