Expanded polystyrene, the moulded white shapes you get as protective packaging when you buy electronics or large toys etc, is a pain to recycle – it can be recycled now but not many places collect it.

Unlike its foam ‘peanuts’ counterpart which can be reused as multi-purpose packaging again and again, the moulded stuff only really fits around the item you got it with — but there are still some fantastic ways to reuse it.

1. Crocks in plant pots

Chunks of expanded polystyrene foam make great crocks for plant pots – particularly large tubs filled with shallow rooted plants. The light foam fills the space rather than heavy soil, making it easier to move around and it helps with drainage too.

Those worried about plastic chemical leaching may want to avoid using it when growing fruit or veg in containers though.

2. Use it to make artwork or to mount pictures on walls

Waste expanded polystyrene can be used to make fun artwork – it can be used as a core for sculptures or models.

Flatter sections can be used like poster board/foam core to mount pictures, photos or posters on walls – the resulting picture is rigid (so won’t curl) but light.

Deeper pieces of the foam can be used to make blocky canvas-style wall art – mount your picture so that it run around the edges, covering the foam sides. If you haven’t got a single piece of polystyrene that’s big enough, make a strong frame from lengths of it instead.

3. Floating bath pillow or bath toys for kids

Pick a reasonably smooth piece of expanded polystyrene and cover it with a quick drying fabric – thin cotton or an old swim suit perhaps – to use it as a floating pillow in the bath.

Or cover smaller, interesting shapes with fun fabric to make floating toys for kids.

4. Use it to make costumes

As it’s light, bulky and reasonably easy to modify, it’s perfect for turning into Halloween or fancy dress costumes where you want to be bulkier – or more robotic/mechanical – than you currently are.

5. Use it for insulation

The air trapped between the individual polystyrene beads makes it an excellent insulator. Some people are worried about using it around the house in case of fires but it can be used in other ways:

• Coldframe – moulded expanded polystyrene boxes are great as cold frames in the garden as they protect delicate seedlings from the cold earth. They’re commonly used for shipping refrigerated vegetables or chilled/frozen fish so ask at your local market to see if they have any spares. Then you just need an old window or some scrap clear plastic sheeting for the top.
• Ponds – if you’re installing a pond, consider placing a layer of expanded polystyrene around the liner and the earth. It’ll stop the cold earth leaching away the water’s last bits of warmth in the winter. You can also float the foam on top of the water in winter to stop it freezing solid – and in the summer, frogs can use polystyrene floats as mock lily pads.
• “Hay” oven – a hay oven allows you to save energy while slow cooking stews & casseroles. You start the casserole on the stove then cover it and put it into a well insulated box for several hours – the retained heat keeps it hot and cooking. As the name suggests, hay is a common insulator – but expanded polystyrene can perform a similar job.

Long time Recycle This-er Lizzy has asked about “the big brussels sprout stalk thing”:

Any ideas for the big brussels sprout stalk things? Oh, and can you eat the leaves that are sometimes on top?

I think the easiest thing to do here would be to reduce in the first place – don’t buy sprouts in the first place, they’re horrible ;)

If you do insist on eating them though, apparently the leaves can be cooked like cabbage. I’ve had less success finding out anything about the stalk though… Other stalks in the Brassica family (like broccoli) can be eaten so it wouldn’t surprise me if you could eat them – just I can’t find any recipes for doing so. Anyone got any suggestions?

As for other reusing ideas, apparently chickens love playing with them – pecking off all the last bits of sprouts. Does anyone know if other small animals (rabbits etc) could nibble at the stalk too?

Any other ideas?

Eileen Bradley left a comment on our “how to make Christmas decorations by reusing and recycling stuff?” post, asking about wishbone fairies:

Does anyone know how to make Christmas Tree Fairies from Chicken or Turkey wishbones. I have seen them made but don’t know how to make them. Thank you

I’ve never seen them – and Google isn’t helping me either so I can’t be any help. Anyone else know more about them? Have you made one? And if so, got any hints/tips to get Eileen started?

Or has anyone got a picture of one so we can see what Eileen means?

(Yes, I know I’m posting about Christmas in November but I thought it might be worth posting it ahead of Thursday, when one or two of our USian readers might be eating turkey.)

After seeing Judith Williamson’s wonderful jewellery made from old sweet tins the other week, I’ve been thinking about what else could be done with them. T’is approaching the season for big tins of chocolates and biscuits after all.

Since they’re well sealing metal tins, they’re great for using for stuff that needs to be kept dry – a sewing kit, next year’s seeds stash, spices, flour, first aid kits/emergency kits, spare nuts & bolts in the garage… What do you store in them?

But do you use them for anything more exciting? Like Judith, have you use them to make anything fun?

We’ve had an email from Stephannie:

Just having our lounge curtains replaced and got a lot of fabric swatches to check out colours etc before hand. Not sure what to do with them now. They’re mostly about A4 size with fractions of big patterns on. Thought about little coin purses or pin cushions but patterns don’t really work for that.

A friend of mine at uni got a book of (admittedly plain) curtain fabric swatches and sewed them together to make a patchwork curtain for over their draughty door. That needs a 60+ swatches though, so probably more than you’ve got.

Earlier in the year, I was looking at basic fabric doorstops – basically cubes with a handle. If you’ve got six swatches that are good colour matches, that might work.

Or colour coordinating mini-quilt padded coasters – where the general colour is more important than the pattern. We’ve got some little padded coasters with cloves in them so they let off a pleasant aroma when “activated” by a hot drink.

Any other suggestions?
