From the BBC (Business) News:
The number of plastic bags given out by major supermarkets in England has risen by 200 million in the past two years to exceed 7.6 billion last year – the equivalent of 140 per person and amounting to 61,000 tonnes in total…
Many shoppers in England will have to pay 5p for plastic carrier bags from Monday (5 October 2015) in a bid to slash the 7.6 billion handed out every year…
The government hopes the English scheme will cut use of plastic carrier bags by up to 80% in supermarkets, and by 50% on the High Street. It also expects to save £60m in litter clean-up costs as well as generating £730m for good causes over the next decade.
I have to admit that I’ve loads at home and this nudge is what’s needed to get me to change. It’s really odd that it’s not happened before and even odder that there’s not been a technological (biodegradable) solution (although I’m sure there have been many attempts).
On the radio today, as it’s topical, there was a discussion on the challenges of developing ‘the perfect plastic bag’. The main problem seems to be to find a polymer that efficiently degrades in very different environments, those with oxygen and those without (such as landfills).
Carl Boardman, from the Open University, was interviewed and he’s optimistic that they’ve found a suitable candidate.
A team at the OU’s Integrated Waste Systems (IWS) research group is working on an ambitious partnership worth around £250,000 with a UK SME, and funded by the Department of Environment, Food and Rural Affairs, to develop a new type of biodegradable single-use plastic carrier bags that is recyclable, biodegradable and will have no harmful effects on plants or animals.
Egged on, he was asked ‘Come on, what can you tell us about it?’ and very sensibly replied with an alarmingly honest ’Nothing!’. Let’s hope it all works out, both technically and commercially.
