Next up in our lunch–themed week…

Like clear plastic muffin/cake boxes, plastic clamshell-ish tubs from salad bars or pre-packed pastas/salads are frustrating – they’re *almost* strong enough and *almost* resealable enough to be reused but not quite.

As with many things of this nature, it’s best to just avoid them when possible so you don’t have to worry about disposing of the tub afterwards – but if you do pick one up, what can you do with it?

I believe most of them are plastic identification number 5 so can be recycled in some places. They can also be used as mini-greenhouses/cloches for very small seedlings.

Any other suggestions?

We’ve had an email from Sarah C:

My kids always need new lunchboxes, what can I do with the old ones?

The hard plastic square ones I used to have when I was little were good kid-size storage boxes so maybe encourage them to use their previous year’s boxes as storage – for pens, letters & birthday cards, small toys – in their bedrooms. If they’re a bit scruffy, they can probably be recovered or painted, and you could make old fashioned suitcase straps & buckles if the plastic catch has broken.

Insulated cooler bags seem to be more common that those though now and from what I’ve read Googling around, they don’t seem to last as long as the hard plastic ones – not so easy to keep them clean. The material could be used to make coffee cup/beer can sleeves – or insulating pipes around the home where space is too tight for expanded foam.

Any other suggestions?

We’ve had an email from Katharyn:

Can you tell me what alternatives I have to plastic milk bottles from the supermarket? I tried to get a milkman to deliver but they told me I don’t get through enough milk to warrant them adding me to the route but I seem to generate lots of empty milk bottles! I can recycle them at the supermarket but I would rather not use them in the first place.

I think the milkman – with their reusable glass bottles – is probably the best route here to go down here – such a shame they won’t deliver. How about talking to your neighbours to see if you can up the order?

Some local wholefood stores also stock milk in glass bottles – talk to them about whether you can return the bottles for reusing or whether they should be recycled with other glass bottles.

If you have to keep using your supermarket, buying in bulk would reduce the amount of plastic used per pint but then you’d have a lot of milk to get through. Milk can be frozen but it can be a little separated on thawing – perfectly fine for cooking with but a little less palatable on your cereal. Any advice on freezing milk?

We’ve had a short but sweet (ha!) email to Compost This from Matea:

Can I put sweets gone sticky in my compost bin?

As with many “can I compost this?” questions, there is no fixed answer that applies 100% of the time in 100% of the situations. In a basic open heap, I’d say no – the sweetness may attracted unwanted insects and if it’s only breaking down slowly, you might end up with a sticky lump in the middle of your heap. Even when it does breakdown, they won’t add that many nutrients to your compost heap – in the same way they’re not exactly nutritious for us to eat either.

In other situations though, sugar can be good for a compost heap – it encourages bacteria growth in bins otherwise lacking (bins filled with leaves usually need more help than bins filled with a mix of stuff including kitchen waste) – so in that situation, you might want to add your sweeties. To avoid the sticky lump thing, you could try heating them up and making them into a runny sugar water solution. Said solution can also apparently be used to perk up weak plants – a soak for bare roots – or even, moving away from compost, overworked bees. What else can they be used to perk up?

Any other uses?

We’ve had an email from Sara:

Hi. I saw everyone’s great ideas about bread bags the other week but we don’t get sliced bread, we get baguettes and the stuff baked in the shop which come in film rather than plastic bread bags. Can that be recycled too?

Ooh, good question. I’m not 100% sure what type of plastic that is – I’ve sent emails to a couple of supermarkets to see if they know so can advise further. It’s maybe cellophane – and if it is, it’s biodegradable. Anyone know?

As for reuses though, it’s not as smooth and, for what of a better word, floppy as the LDPE/number 4 plastic used for pre-packed bread – but because of that, it would be better to use as a lightweight packaging material (it would scrunch, not crush flat). It’s not as pretty as the plastic wrap used on bouquets but there might be some overlap in the reuses.

Any other suggestions?
