We’ve had an email from long-time commenter Melinda:

I’ve recently been struck with the foil linings of snack bags, and even dog food bags. Has anyone used these to create something solar, such as a cooker? What items have been put to solar use and how?

Making a solar cooker is on my to-do list for this year but I’ve not done it yet (and probably missed the hottest, sun-powered days – doh!) so I can’t advice on that. Anyone else got any experience making those? I was probably going to make something like this cardboard one to start with.

I also wonder if they’d be useful as soft mirrors behind plants, to reflect a bit of the light to the non-sunny side of the plant — a similar idea but, hopefully, without the cooking!

Any suggestions or tips for Melinda? Or any other solar related ideas?

Over on the Suggest an Item page, Emily asked:

Would anybody have any ideas for reusing the bags that stock feed comes in? They are some sort of plastic and not recycleable.

Funnily enough, I had this on my to-do list already as I’m starting to be overrun with the things too – and I’ve only got six small chickens, so I can’t imagine how many are generated by people with lots of animals/birds. (Mine are the heavy-duty flat plastic types – we’ve covered the woven plastic type ones before.)

The things I already do with mine:

• refill them with bedding & litter when cleaning out the coop. I bag it sometimes rather than tipping it all into the compost heap so I can give it to friends/family as fertiliser. Such a lovely gift! ;)
• use them to line the wooden planters I make. (I do this with some hesitation for fruit/veg containers as I don’t know what plastic it is so there may be some leaching issues.)
• use them as rubble sacks – they’re not quite as strong as actual rubble sacks but still pretty useful

I also know some people use them to “waterproof” ceilings of hen/duck houses, and I have a plan to build up the floor in our coop, and will cover it with these bags to make it easier to clean. Away from chicken stuff, I’ve seen people using opaque bags as weed barriers around trees.

Any other suggestions for ways to reuse them? Or any advice on recycling?

One thing I would say, as ever, is try to reduce your collection of them – look to see if there are any paper-bagged alternatives. If you’re storing the feed in a dry place, the paper getting damp shouldn’t be an issue. The heavy paper could be composted or recycled. Any other advice?

We’ve had an email from Natasha:

It seems a good number of my terracotta plant pots cracked in the cold over winter. What can I reuse them for?

Holding your horses, you may be able to repair them if it’s just a relatively clean crack – this Instructable fixes a broken-in-half pot with epoxy resin, this how-to uses silicone sealant and wire, and this eHow also uses wire. Anyone got any fixing/mending advice?

Even it’s beyond repair, don’t discount it as still being useful as a planter – some people make very effective use of broken pots to create a shabby chic/Roman ruins feel for the garden.

If it’s even beyond that though, broken up, it could still be useful in the garden – providing interesting/useful shade for aquatic life in a pond or as water draining crocks at the bottom of the new replacement plant pots.

(And don’t forget to stop history repeating itself by protecting terracotta and the like over winter. From what I’ve read, pots fired to a higher temperature are more frost resistant too, so look out for “frost proof” pots too.)

Any other repair or reuse suggestions?

Readers of my simple/DIY living blog The Really Good Life will already know that I’m trying to make more efficient use of the space in my garden this year – I’ve been making lots of planters and raised beds from scrap wood (including this weekend, a 3ftx3ft bed for square foot gardening from our old bathroom cupboard doors) and I’m also interested in vertical gardening – creating a living wall of salad, herbs and companion plants.

I’ve explored the various different types of wall planters/hangers that you can buy – from essentially shelves, to window boxes, fabric bags and complicated systems – but me being me, I would prefer to make them myself, ideally reusing and recycling stuff I already have stashed around the place.

Some lovely people have already made some suggestions – I’m going to try making upside down planters from squash bottles and a fancy living wall type system from an old pallet when I find a suitable one – but I thought I’d ask on here as well in case anyone else has any suggestions.

I realise we’ve already covered similar areas like this before but I think the wall-mounted aspect opens up some other options – and I’d love to hear them.

What have you used to make wall planters? Have you made a vertical garden or a living wall? Or have you made any hanging baskets from anything interesting?

We’ve had an email from Paul:

We’ve got an extraction system at our joinery shop which produces big bags of sawdust but we use a lot of MDF and other particle boards so it can’t be used for animal bedding. Do you know how they could be recycled?

We’ve covered wood shavings recycling before but the obvious answer there was animal bedding – lots of people want rid of them and lots of people want it! The MDF dust is a bit of a stick in the wheels though – as Paul says, there are issues using MDF dust in animal bedding — the dust is so fine it can easily be kicked up and lead to respiratory problems.

So what else can be done with it? I did wonder whether it could be pressed into wooden pellets for biomass boilers but apparently the glues/chemicals used in particle board construction may be problematic – an undesirable contaminant. Any other ideas?
