About twenty years ago, I remember reading that ‘the average British Household contains at least 17 plastic carrier bags’ and for many years I have been trying to decrease my carrier bag use.
I have paid extra to get the more durable ‘bags for life’, collected freebie ‘promotional’ cotton carrier bags from exhibitions, used blue plastic shopping boxes from Sainsbury’s …and made myself [and countless other friends and family members] little storage bags to hang on the back of the kitchen door to hold rolled up plastic bags ready for re-use.

However the results of a recent study “to assess the life cycle environmental impacts of the production, use and disposal of carrier bags for the UK in 2006” were very interesting.

Those lovely cotton bags have a greater carbon footprint, and I must use my fabric one 131 times to match a single use of a plastic bag!

And if I re-use just 40% of my plastic carriers as bin liners, then that means 173 outings for the cloth bag [or 5 for the Bag For Life]

Re-using every plastic bag as a bin liner reduces the carbon footprint still more – and means 327 trips to Sainsbury’s for my fabric tote to match the footprint.

And if I manage to re-use the plastic bag three times – then I need to use the cotton one 393 times. [these charts from the BBC]

So what’s the answer? It is not always possible to re-use plastic bags- many are very flimsy and the sharp corner of a box, or a couple of heavy bottles can render a bag split and unusable half way home – so the bag doesn’t manage one journey, let alone a repeat.
I left a ‘biodegradable’ bag full of buttons behind a chair in the conservatory one summer. When I picked it up in the autumn, it had already been degraded by warmth and sunlight, and the buttons went everywhere!
I try to decline a bag when I shop, and keep a cotton bag rolled up in my handbag when I go out. It is not always avoidable though, and sometimes you need a waterproof bag. The blue bag of leeks in last week got at least 2 re-uses before lining my bin.
You can of course re-use in craft projects. Back in London I helped over 40 Girls’ Brigade girls make Christmas Wreaths with the bright green carriers that M&S used in the 80’s. 25 bags per wreath!

Many of our GB families used these weatherproof decorations year after year [and may still be doing so for all I know] Does that count as multiple re-use?
And there are groups who knit bags into warm and durable blankets to distribute to homeless folk.

This Little Wonderwoman looks pleased with the blanket donations she has just made!
In the past week, I have acquired two bags, reused 5 in a shopping trip, discarded one, after it split on the return journey [the assistant commented on its age – it bore an ad for a Sainsbury's Campaign in 1999] and used 3 as bin liners, which disappeared to the landfill on the dustcart.
That’s a net loss of two bags over the week. I now have eighteen in the house. At this rate, I ought to be without plastic bags by June.
Do you use plastic bags? and re-use them?
How many uses do you get from cotton bags?
Have you a ‘favourite’ bag?
