Recycling Polystyrene

Yesterday I was asked this question on Twitter…

Technically the answer is 'Yes' - Polystyrene can be recycled and I learnt when I visited the Resource and Waste Management Show in Birmingham last year that it is recycled in the UK.

The map on this link shows you where in Britain you can find polystyrene recycling points.

But likely the more practicable answer here is NO.  Why?  The problem lies in collecting waste streams for stuff that is not an everyday waste item.  In addition, polystyrene is very light and bulky- it is actually 98% air!  That's the reason it is a good item for packaging, but a bad item for recycling.

In West Oxfordshire we are asked to put polystyrene into our grey rubbish bins - the ones for residual waste.  Would I do that?  NO WAY!

Polystyrene is one of those things I actively avoid whenever I can so I don't get a lot of it.  For instance I won't buy something in a supermarket that is packed in a polystyrene food tray.  I don't understand why a food processing company would choose a material that is so rarely recycled to package something they want us to buy on a regular basis and so I won't give them my business. Plain as that!

However, I have found that people will bring things to my house that are packed in polystyrene and occasionally I have had parcels arrive protected by polystyrene or filled with polystyrene pellets.  So what do I do with them?

I turn it into a resource and reuse it.

A timely project for polystyrene right now is for potting up my geraniums to bring them indoors for the winter, which I do every year towards the end of October.  Of course, I save the polystyrene from previous years but each year my geranium collection grows by about half a dozen plants as I take cuttings and separate bits of plant that have naturally rooted during the year.  So I always need a bit more polystyrene or broken crock for the bottom of the plant pots. For this purpose, I keep a bucket in my garage into which any bits of polystyrene or broken cups and plates get stored until I need them.

This is last year's stock about to get used this weekend.

A couple of other projects that have used up my stock of polystyrene lately:

This planter that Mr Pitt made for me out of some recycled wooden planks needed quite a lot of drainage in the bottom.  Polystyrene was ideal for that as it does the job of rocks and pebbles - but without the weight.  It keeps the soil in but allows the water to find ways through and creates a dry zone between the soil and the wooden base of the planter so that the wood doesn't rot.

You may notice that it also used up my collection of bits of oasis from various flower arrangements acquired at weddings, several cricket dinners and a few other events.  I always knew I'd find a use for it eventually!

Secondly, my local community shop that raises lots of money for our village clubs and societies sells quite a few fragile things, so I recently took a bag full of tissue paper and some polystyrene packaging pellets to them, which they said they were always in need of.

If you don't have storage space for your polystyrene in a garage for example then you could maybe put it on Freegle.  I often find things will go same day or within a couple of days.  People use polystyrene sheets as insulation in greenhouses.  It would make a reasonable substitute for oasis for dried flower arrangements too.

Good article!!Except that, waste polystyrene can also be recycled through some kind of machines. Our company INTCO has these kinds of machines, such as compactors, melters, dewatering machines. Here is our website about these different kinds of machines.
