We’ve had an email from Pauline:

I would like to use steel and aluminium cans to make jewelery. Do you know how to cut the metal out? Should the can be crushed first? Do you know how to smooth the edges so they don’t cut? If you could throw any light on this or point me to a website as I am not getting much coming up in google at the moment? Thanks.

I’ve made numerous things out of drinks cans (all aluminium I think) over the years and have mostly just used scissors for the cutting – it’s not as hard to cut as you’d think. I might use a can opener to remove the lid or a knife to start a hole in the body but then scissors suffice. I typically cut down the print “seam” and around the top & bottom to remove the curve so am left with a flat rectangle of metal.

(I’ve tried using shaped hole punches on cans but only lightweight ones so not had much success. Alison Bailey Smith has talked about the heavy duty ones she uses on plastic – I wonder if they’d be good on metal.)

And if the edges are smooth, not jagged, they’re also not as sharp as you might think. I’m not saying I’d necessarily want to wear them as jewellery in their nude state but in all my making, I’ve not once cut myself. Anyone got any tips for making the edges safer though?

Finally, anyone made any interesting jewellery from cans – or seen any inspiring examples of work around the wonderful worldwide web?

While we’ve covered food cans in general before, Danielle emailed asking tuna cans in particular:

i have so many, what can i do with them?

There’s a wide variety of uses for tuna cans:

I know some people use them to make “buddy burner” candles and you can use them as candle holders too – but make sure you put a bit of sand in the bottom first to absorb the heat from the candle rather than it heating the metal.

Some people clean them up and use them as “cookie cutters” for making large biscuits/cookies, and because everything in this house gets commandeered for the purpose sooner or later, I’ve used them as drip saucers under plant pots (pull the label off and leave them silver for an industrial look, paint them to make them look prettier – shiny white or cream gloss gives a pseudo-vintage enamel look).

Since they’re essentially just a small pot with a low centre of gravity, they’re useful for holding small quantities of paint/glue. Or as students have been known to do – use them as makeshift ashtrays.

Any other suggestions?

We’ve had an email from Jo:

Hi. Got a question for you. Is it better to buy pop in big bottles or cans from a packaging point of view? Big bottles seem like less waste for the amount of liquid but are plastic. Your thoughts?

Neither are great for a number of reasons. Aside from the actual waste from the packaging, it’s really resource-intensive to ship around liquid in anything other than pipes – and the production tends to be pretty bad for the environment too, let’s not forget about the production.

But to the question in hand, both the plastic and metal are non-renewable resources, the creation of which is very destructive to the environment, but both can be recycled and are widely collected. If though, you can only recycle one or the other in your local area, that might sway you one way or the other.

The easiest way to reduce the waste is, of course, to reduce consumption of the drinks in the first place. Or make them at home – either getting the fizz through a natural process (like making homemade ginger beer) or a less natural one.

I usually prefer bottles – we don’t drink much fizzy stuff at all and when we do have it, prefer little amounts rather than full cans – and even though we no longer have doorstep recycling of plastics, plastic bottles have more reuses around the home and garden.

Anyone else got any input? What about suggestions for reducing the amount of fizzy drinks drunk – what are similar but better alternatives?

We’ve always tried to minimise the amount of waste our cats produce by buying in bulk where possible, choose recyclable packaging over plastic bags and they mostly eat biscuits, which have less water content so aren’t as heavy/bulky to ship.

Except now one of them is sick – very sick – and is having trouble digesting regular cat food. I’ve become incredibly familiar with cat food ingredients (and also the consistency of cat poop) over the last few months and the better quality stuff (stuff that is made up of at least 50 or 60% the meat/fish it claims to be – most cat food is around 4%) seems to come in small quantities in plastic pouches, or tiny, teeny cans. Enter loads of extra waste.

I try to feed her frozen fish/mince at least once a day – since that has a considerably lower packaging cost – but worry that she’ll miss out on essential vitamins/minerals if I just feed her those all the time. I’m happy to make her food from scratch but don’t have time to do it at every meal time since she’s eating lots of small meals throughout the day. I’ve tried making a chicken & rice mash before but it didn’t really interest her.

Unfortunately for us, this is a short scale problem with this cat (*sniff*) but looking at the ingredient lists on the standard cat food boxes & cans has made me want to do better by the other cats.

So has anyone got any suggestions for how I can reduce the amount of cat food packaging waste we’re producing? Anyone found any decent quality cat food (dry or wet) in large quantities rather than tiny sachets? Any popular homemade cat food recipes?

Around our area, it’s unusual to see a take-out place without empty big cooking oil cans outside.

Hopefully they’re recycled as part of a commercial doorstep recycling programme but most of time it seems like they’re going to landfill – here they were next to a skip filled with other random rubbish. Very frustrating.

If we took some of them, what could we do with them? I know after intensive cleaning, crude oil barrels can be made into woodburners/rocket stoves and barbecues – could these essentially big tin cans be used for a similar thing on a smaller scale or is the metal not heavy duty enough?

With the top taken off (and the edge made safe), I imagine they could be turned into planters for the garden – albeit ones that might rust over time.

Any other suggestions?
