We’ve had an email from Joe, who works for a fancy handbag designer with a number of select boutiques around the UK:

I am trying to find a way to recycle these display Perspex props. We used them in lots of our London stores and have loads of them. Sadly they are mostly all damaged so I don’t think anybody else would want them.

I really don’t want to throw them away and am trying to find out what to do with them.

It is possible to recycle perspex (aka plexiglas, lucite or acrylic glass) but it’s not widely done post-consumer — I can only find details of a scheme which aimed at collecting offcuts & waste from perspex manufacturers. (In case anyone is interested, it was the Amari Recycling Initiative – does anyone know any post-consumer collection?)

Even damaged, the raw material might be usable by makers/crafters. Local art schools (or just the the art/design&tech depts of normal schools), hacker/maker groups (such as hackspaces) or scrapstores would probably all welcome the donation – and depending on the area/amount, might even be able to do a collection. Or someone on Freecycle/Freegle might want them too.

Any other suggestions for recycling/reusing them en masse? Or individual projects for small pieces of perspex?

Is there a word for when you’re window-shopping skips? I was skip-gazing (?) around the corner the other day and as well as having a mighty fine looking pallet in there (yoiiiiink), there were several old paint roller trays flung on top.

Compared to rollers, paint trays are super easy to clean (especially if you line them with a carrier bag first) so I don’t know why they were thrown out. There were a couple of emulsion ones and a couple of smaller gloss ones.

We’ve got plenty of trays for painting ourselves but I guess I could rinse them off and offer them on Freecycle or something.

As for reuses, in the past, I’ve used old roller trays as drip trays under seedlings (the deep part is more useful if you’re carrying them around, they have a tendency to wobble off the shelf bit – but that’s fine catching run off if it’s in one place). What else can be done with them?

The other day, John and I were hanging around a dumpster at the back of an ice cream parlour — as you do — and spotted it was full of 5ltr plastic ice cream tubs.

In our house, ice cream tubs are one of our favourite plastics to reuse – rectangular 1ltr square tubs are just the right size of storing leftovers and the 2ltr ones are useful for other storage stuff (three current reuses: we’ve got one for chicken scraps in the kitchen, I’ve got unplanted seeds in another and a third & fourth are used for batteries – one for new batteries, the other for batteries heading to recycling) – and they’re usually made from reasonably commonly recyclable types of plastic – the ones I’ve got here are Polypropylene, resin code 5. To be honest, I was quite surprised that this ice cream parlour didn’t have a recycling scheme in place since it surely generated a fair number every day.

Next time we’re in the environs, I’m tempted to ask if I can have a dozen or so to reuse. They were about 30cm (1ft) or so long, about 15cm/6″ tall and the same wide. I’ve got loads of office and craft stuff that need to be stored better and a row of those on a shelf might be a neat way to do it.

They’d also work on the thin counter in our porch as planters for growing salad etc – although I am trying to move away from growing stuff in plastic. Storage and planters – my reuse ideas for just about everything at the moment, which I think gives a rather telling glance into our life ;)

What about other reuses?

Between the good weather and the World Cup, every weekend recently has been barbeque-madness in the UK, which means the burger, salad and salad accompaniments shelves at the supermarket are stripped bare by 10am, just a solitary limp iceberg lettuce left behind to tell of the devastation.

Pre-packed prepared food like coleslaw, potato salad, bean salad or cous cous – and most salad bar tubs I’ve seen – come in plastic tubs with resealable lids, but the plastic tends to be a bit lightweight & flimsy – so not as ripe for reusing as they might be.

What do you use them for? They seem a little too flimsy to me to use as storage tubs in the kitchen – not rigid enough to clean properly.

Plant pots? Again, not the most stable plant pots in the world but a lot of starter modules/seedling pots tend to be a similar quality so they could be used for that.

Since they’re often mostly transparent, they’d also be useful for storing little items like screws or beads.

Any other reuse suggestions?

There is also obviously a potential “reduce” angle here too – it’s not hard to make these things. Unfortunately if you use mayonnaise or the like in the coleslaw/potato salad, it’s advice not to freeze it because the mayo is likely to separate on thawing — but if you think ahead, you could freeze ideal-portion-size amounts of the shredded vegetables mixed together, or cooked potatoes – so then it’s a doddle to made them when you need them: just defrost and add the mayo & any other seasonings. Or you can make special recipes for freezing – such as freezer slaw.

What are your favourite recipe ideas?

We’ve had an email from Martyn:

Can solid pond liners be recycled? If so, where please?

As far as I can see, rigid pond liners tend to be made from fibreglass and as we discovered last time we had a fibreglass item on here, fibreglass can be recycled but isn’t widely done so.

A better idea would be to reuse the pond liner. They apparently have a 20 year lifespan as ponds but after that they, presumably, begin to leak. (No one mentions what happens after that 20 years – I hope it’s start to leak and not explode violently killing everyone in a 50m radius. Because that would be bad.) If you don’t need it as a pond any more, offer it on Freecycle/Freegle to someone who wants one. Or if it’s started to leak and is beyond repair, you (or someone else) might want to use it as a planter or the like.

Any other ideas?

And what about reuse ideas for flexible PVC pond liners that have been damaged or are leaking?
