Next Sunday is World Water Day so I thought we’d run with that theme here on Recycle This this week.

Hopefully we’re all already doing what we can to reduce our water consumption – low-flush toilets, taking showers rather than baths, turning the tap off between rinses when cleaning our teeth, a water butt or two in the garden, etc – but what about reusing greywater from around the house – from that shower or bath, for example?

Proper greywater systems, which recycle washing water to flush toilets, can be expensive (in terms of set-up and space) to fit but drop household water usage by around 30%.

I know other people with showers-over baths take care with their soap use and save the water to use on their gardens, or use the still pretty-clean water to pre-soak heavily soiled clothes. (I take muddy clothes into the shower with me and stomp about on them to get the muck out before washing them as normal, saves needing a second run through the machine.)

Any other practical ways to reuse that water?

It’s International Women’s Day on Sunday (8th March) and over at Things To Do Today today, I’ve linked to a number of posts about green sanitary protection alternatives.

We’ve featured what do to with unused but unwanted sanitary towels and tampons on here before and there were lots of good suggestions including keeping towels around to use as bandages in emergencies and making tampons into art/a Thanksgiving centrepiece ;)

But what can be done with expired menstrual cups?

Manufacturers such as Diva Cup and Mooncup recommend they’re replaced every year because of government advice on silicone and because of the “personal, hygienic nature” of the product. I know some people keep using them anyway if the silicone is still in good condition because it seems such as waste to just fling them out – but I wonder if there are any ways to reuse it for other purposes instead.

And what about recycling? Silicone is recyclable, just not particularly widely – are there are programmes to recycle these cups in particular?

We’ve had a query from Alison Bailey Smith:

Can we have suggestions for what to do with divided yoghurt pots, you know the kind that have muesli in a small triangular pot with larger triangular pot for yoghurt? I mean beyond using as paint and water pots…

I have used them for the basis for papier mache. We go through tonnes of them and give them to school and playgroup but wondered if anyone had converted them into anything unusual.

We’ve covered the single pot type of yogurt pots before but these ones are quite different – so any ideas?

We’ve had an email from Natalie:

We’ve been buying little cheese from our local farmers’ market which are covered in wax like Edam or Babybell, except they’re all different colours.

Can we use the wax to make candles?

I’ve never made candles so I’m not 100% sure but my research (reading Wikipedia) tells me that cheese wax is typically paraffin wax and that can be used for candle making (although some people prefer to avoid it…)

Apparently it can also be used for sealing jars, bottles and the like so that might be an option if you make your own preserves or pickles.

Anyone else know anything more about making it into candles? And what about other reuses?

• How can I reuse or recycle … old candles?

We’ve had a message from Helen, asking:

I have a rubber bath mat that the kids don’t seem to need any more. It’s (to be frank) a bit manky so I feel I can’t freecycle it. However I don’t want to just chuck it either. Is there a way to recycle something like this?

All suggestions gratefully received!

I’m sure there are tons of ways to reuse them around the home and garden. The first ones that spring to mind take advantage of the fact it’s non-slip – cut circles out of the least manky parts and there you go, non-slip mats for underneath plant pots or the like

Any other ideas?

(Oh, and if you’re wondering about fabric bathmats, we covered them a few months ago.)
