Planet Earth's new nemesis?
![]() British shoppers get though eight billion a year, but elsewhere the humble plastic bag has become a menace, with one country even banning them outright. Could the UK follow suit?
Supermarket shopping in Ireland is much the same as anywhere in Europe, or indeed the rest of the world. But one element British shoppers would find distinctly foreign is the need to pay for plastic bags at the checkout.
The idea was introduced as an attempt to curb the litter problem created by so many bags. And anecdotally, at least, it seems to be working. Within a couple of months, shoppers have switched to re-using carrier bags. Customers now routinely turn up "pre-armed" with a clutch of polythene and one of the biggest chains, Superquinn, says the number of bags it distributes has dropped by 97.5%. Being thoughtless Now there is speculation that the UK could follow suit. Environment minister Michael Meacher is said to be interested in the scheme and the environment department says it has "concerns about the number of plastic bags that are routinely handed over by supermarkets".
Made of polyethylene - more commonly known as polythene - they are hazardous to manufacture and are said to take up to 1,000 years to decompose. Elsewhere in the world, their role in environmental destruction is even more drastic and so, it seems, a revolt has begun against the humble plastic bag. In March, Bangladesh slapped an outright ban on all polythene bags after they were found to have been the main culprit during the 1988 and 1998 floods that submerged two-thirds of the country. The problem was that discarded bags were choking the drainage system 'Plastic flower' Taiwan is moving to ban the free distribution of plastic bags, while, next month, the government in Singapore will launch a campaign to discourage their use.
In South Africa, they have been dubbed the "national flower" because so many can be seen flapping from fences and caught in bushes. They are even big in America, despite all those Hollywood films featuring "moms", returning from the supermarket, overburdened with paper bags. Four out of five grocery bags in the US are now plastic. From paper to plastic Yet this trend is a fairly recent phenomenon; the result of advancements in manufacturing.
"Plastic was the material of choice in those days and it was more hygienic, if for example something spilt as you carried your shopping home." It is also stronger and faired better in the damp British climate. Crucially, however, plastic bags have become cheaper than paper. The so called "T-shirt" bags that are freely available at supermarkets are made of lightweight, high-density polythene. 'A people problem' They cost and weigh a fraction of the older and thicker, stretchy polythene bag that shops used to charge for.
Not surprisingly, those with a stake in the industry deny reports of its demise. The fault is with human behaviour, not the bags themselves, says Peter Woodall of the Packaging and Industrial Films Association. "Lots of people recycle them as bin bags. If you make people pay for them, they will have to go out and buy separate bin bags," says Mr Woodall. "Plastic requires a great deal less energy in manufacturing than paper and because the vast majority of our plastic bags are imported from Asia, a switch back to heavier paper bags, means it would take more energy to bring them over." So for the meantime at least, British shoppers will continue to see plastic as fantastic.
