In honour of International Women’s Day on Monday, we’re having a week of women’s & sexual health themed posts (and giveaways!!). Check out our older related posts too – such as unused disposable sanitary products or end-of-life menstrual cups.

I thought long and hard about whether to feature this because it’s the type of green action that makes Daily Mail readers exclaim “bloody hippies!!” and pledge to not reduce, reuse or recycle just to annoy us filthy, poor Good-Life-wannabes. But in the end, Cipollina’s comment yesterday convinced me – it’s not for everyone but blood is a cracking fertiliser.

The fluid emptied out from your Mooncup or pink water from rinsing out from your washable sanitary towels is a great source of natural nitrogen – it replenishes overworked soil and feeds the plants. People buy blood meal — the dried & powdered blood from livestock — as a non-synthetic fertiliser but why not cut out the middle man/middle cow? It’s as organic as you are.

There are some potential problems with just pouring it straight on the garden – some blood-borne pathogens can be transferred around and apparently it can attract ants – but one way to minimise the risk of that sort of thing is to put it through a hot compost heap. If you know you have a blood-borne pathogen, you might want to look into the situation with your condition further – although apparently even hepatitis, one of the longest surviving blood-borne pathogens outside the body, only manages about 30 hours before breaking down (shorter if heated/exposed to sunlight).

I found two very interesting discussions on the topic – this one and this one – explaining about different people’s experiences and methods but I wonder if anyone has used it for anything a bit more out of the ordinary…

Thoughts? Ideas? Suggestions?

We’ve had an email from Sally asking about squeezy hand cream tubes:

Do you know what number plastic hand cream tubes are? The ones with the flip lids. I don’t know whether or not to put them in my recycling bin.

Along with the inconsistency of facilities available, lack of information on packaging is one of my major pet hates when it comes to recycling. I’ve got three different types of face/hand moisturiser in our bathroom cupboard and only one has recycling information on it – it’s number 4 (LDPE). LDPE isn’t as widely recycled as PET/PETE (number 1) or HDPE (number 2) but it is recycled in some areas – my old council Leeds used to pick it up at the kerbside so it’ll be worth checking your local advice to see if you can do the same.

Aside from recycling, any ideas on how the tubes can be reused? I suspect there will be some overlap with squeezable plastic toothpaste tubes but any new suggestions?

We’ve had an email from Judy, asking about reuses for asthma spacers:

Y’know, the big plastic cone things where you put the inhaler in one end? They are now being recommended for adults too so there must be millions out there.

I understand hospitals in Australia sterilise them for reuse.

In third world countries kids sometimes have to use empty water bottles and although I did read these are effective it seems wrong to have one standard for our kids and one for other people’s. I mean if they are *that* effective why are we getting the *proper* version on the NHS and not using old bottles ourselves? They ain’t cheap either as anyone who has had to buy a spare will know.

Apparently there have been several studies proving that plastic bottles just about as effective as the specially produced ones – I guess the (cynical) answer to Judy’s “why aren’t we just using bottles?” question is that someone realised there was a buck to be had making something special ;)

So that’s one way to make them by recycling/reusing something that is usually considered waste – but what are the options for used purpose-built asthma spacers? Does anyone know of any sterilising/redistribution schemes?

We’ve had an email from Plum:

We’ve got five bottles of mouthwash in the bathroom cupboard – all tried once but never again because they were vile! I was wondering if you had an idea if they could be used for any household cleaning tasks like brown sauce on brass.

Good question. In my experience, most awful tasting mouthwashes are very alcohol-y and alcohol does have antibacterial/antiseptic qualities — does anyone know if it would be enough for cleaning instead of rubbing alcohol?

If you don’t mind having a minty face, I suspect it could be used as a facial toner – a lot of toners have similar amounts of alcohol in them (although alcohol in toners is very drying – the best skin thing I ever did was switching away to alcohol-free cleaning products).

Any other suggestions?

We’ve had a rather specific question from Douglas but we sometimes get incredibly informative responses to these type of questions so I thought it was worth posting in case anyone knows anything:

I was wondering if you knew of a way that I could reuse blocks that have been milled using a CNC machine (as known as rapid prototyping) The block are made out of zirconia and are use for the 3M Lava milling center. I hope you can help although i understand if not as this is and incredibly odd request since it is so specific.

So … anyone? I’ve not been able to find anything particularly useful on Google and I’ve sent a message to 3M about it but not heard anything back yet. Anyone else in a similar position?
