We’ve had a email from Jo:

Love the new Reduce This thing. I’ve got a question about babywipes. At home we use wash cloths for wiping sticky faces and hands but those little packs of disposable wipes are so much more convenient when we’re out and about. Does anyone have any alternatives?

You could put a damp cloth in an old re-sealable baby wipe container – either a thick washcloth or thinner clothes like hankies. They probably would get mouldy if left in there for more than a few hours though so you’d would have to get into the habit of remembering to take them out again after your excursion.

There is, of course, always the spit-on-a-hankie method much loved in mum-stereotypes too ;)

Any other suggestions? What did your mum/grandma do?

We’ve had a little (1ftx3ft) greenhouse in our garden for about five years now – it started off as an actual greenhouse for growing things in but quickly became the cats’ favourite hang-out and the winter home of the local stray cat, so we dropped the growing things pretence and it’s now kitted out with old sofa cushions for the ultimate cat luxury.

It’s a simple – cheap – thing: hollow metal tubes and two shelves, covered by a shaped plastic sheet, with a zipped door flap at the front. The main problem we’ve had is when one cat is in the greenhouse, it’s not uncommon for a second cat to sleep on the roof – and under the heat of the sun/weight of the cat, the roof sags and eventually rips. That’s happened twice now and we’ve repaired it for as long as possible, then ordered new covers off the internetz – still not ideal though.

I’ve looked into buying little glass/solid plastic paned ones but they’re pretty rare compared to large ones and seem really expensive for the size of them. We’ve not got room for a big greenhouse but it would be great to make one that could be used by both the cats and our growing needs.

I know some people make them with old windows and they’ll depend on exactly what type of windows are at hand but anyone got any suggestions/advice? What other types of materials could I use? Does it have to be clear-clear or is reasonably translucent enough? What shape would be best – square? sloped roof? round? polytunnel-ish? biodome?

Alice’s last “Reduce This” question is:

How to reduce the energy I use in cooking.

I’ve started putting any extra water I boil in the kettle into a thermos flask ready for the next cup of tea, but there must be loads of other ways to cut this down too.

We talked about ways to make the most out of boiled water back during our water week for World Water Day in March but I like this new focus on energy.

The biggest thing I think is using pan lids where possible – it amazes me how much less gas is needed to keep something at a rolling boil when there is a lid on the pan. I’d also recommend getting a range of pan sizes and using the most appropriate one for the task in hand particularly when boiling things in water – boiling eggs (which required a certain depth of water no matter what the diameter of the pan) being a prime example.

What have you tried? What works? What doesn’t?

Has anyone tried alternative cooking methods to cut down on fossil fuel use such as solar ovens?

We’ve had an email from Allison:

We always have coffee in for visitors but rarely use more than a few spoonfuls of it before it goes out of date. Can I do anything it?

The only reuse I can think of off the top of my head is making ye olde stained paper when I was a kid – possibly not the most useful suggestion unless you really, really like making fake old maps ;)

A quick Google reveals some more useful things – they can be used as a scent in soapmaking, dying fabric or even to develop camera film.

Any other ideas?

After an idea sparked by [Am] last year and added to by Alice last week, I’ve started adding ‘Top Tips’ boxes to the most popular Recycle This pages (the ones with loads of comments) to highlight the best suggestions for reducing, reusing and recycling. It’s pretty time consuming but lots of fun, re-reading all the great suggestions that have come in over the last 3.5 years — you guys are wonderfully creative and inspiring! you’re awesome!

Anyway, while I was doing the old keys one the other day, I saw that the British charity, Guide Dogs for the Blind collect old house keys as a fundraiser – and they collect old coins too.

Like old stamps, certain ones are obviously highly collectable but there must be a lot that aren’t quite so popular – all those bogstandard 5pences and 10pences that were replaced in the 1990s for example.

Any creative or practical suggestions of things that can be done with them? Any other charities that collect them?

I also used to know about half a dozen charities who collect leftover change from overseas excursions but can’t think of any of them right now – anyone know of any?
