With their semi-rigid sides & strong handle, plastic milk bottles are very easily reusable – which is useful since there are bajillions generated every day.

We’ve had loads of great suggestions about them over the years but here are some of my favourites:

1. Pencil sorter
Mentioned as a featured link a few weeks ago, I love how neat and practical these containers are for coloured pencils/pens. Stored on a shelf, the lids could be painted the colour of the pencils to make for easy identification.

2. Paint caddy
One close to my heart at the moment because we’re decorating – plastic milk jugs make great paint caddies. 4 pint/half-gallon/2ltr bottles are best for this – cut out the panel of plastic opposite the handle, leave the neck intact for strength and cut down to about half way. The handle is easy to hold (or you could loop some wire/string around it to hang it from a ladder rung) and the caddy holds about 2 pints/1ltr of paint at a time – enough to do a fair amount of painting.

3. Foraging container
SandyM’s family use gallon milk bottles as foraging containers – widen the neck and add a loop of rope or a strong belt through the handle holds it up, leaving both hands free for collecting fruit. In the UK, our bottles tend to be long & thin, so possibly the wrong shape for this – but a great idea if you can get hold of those bigger square bottles.

4. Bird feeder
One of the original ideas for reusing them – make them into bird feeders. The how-to uses gallon jugs but the same theory can be applied to smaller ones too – I’ve made mini ones for our mini-tree from 1ltr/2pint bottles.

(I’ve also used a plastic milk bottle as a grit hopper for our chickens – same principle as the bird feeder but with stones/shells instead of food. It would be a cruel joke if they didn’t need the grit for digestion.)

5. Scoops
Cut away a wedge from the bottom to make it into a scoop – for scooping flour/grain/animal feed or other dry goods, or at the other end, as a pet poop scoop. Leave the lid on to avoid spills from the other end.

What are your favourite reuses for plastic milk bottles?

• How can I reuse or recycle plastic milk bottles?
• How can I reduce my use of plastic milk bottles?
• How can I reuse or recycle milk bottle tops?

• I’m a big fan of reusing milk bottles for all sorts of things and this idea for using them as stationery organisers is fantastic. If they were for use by little delicate hands, I’d be tempted to sticky-tape the cut edges to make them less sharp.
• Kristin from Craft Leftovers used the offcuts from fitting a bamboo blind to make coordinating twined coasters.
• Jan McNeil, a Sculpture & Photography student from the University of Ulster, emailed to ask if anyone has any old baby dummies/pacifiers lying around – she wants them for an art project. Get in touch if you’ve got some – or have any ideas for where she might be able to get them from – and I’ll pass your details/suggestions along.
• I love the idea of this toothbrush holder made out of old toothpaste tubes. (Although I’d want to make sure it was easy to clean – which, with the lips, I’m not sure it would be in this design).
• This reusable lunch bag how-to uses new shower curtains but it could equally be made from a clean old one. A great way to reuse to reduce.
• Someone – a name didn’t make it through so I don’t know who – sent over some photos of a birthday table cloth made from old balloons: “I recycle my birthday ballons by gluing them to a clear plastic sheet, gotten in the fabric dept. They make a cute table cover for the party!”

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?
