Plastic bag ban myths busted
IT’S time to trash some of the myths flying around in the shopping bag ban debate.
With free bags being banned, climate-change deniers are lining up to argue why the phasing out of singleuse plastic bags is a bad idea.
Predictably, there is a huge amount of misinformation being peddled by those who don’t want it to work. So here are some facts.
A single-use plastic bag ban simply won’t work: Bans on free supermarket bags have worked well in other countries.
Leading the pack is Ireland which introduced a 15c charge in 2002 which was increased to 32c five years later. By 2012, each shopper used only 14 bags a year — down from 350. This meant plastic bags went from accounting for 5 per cent of rubbish to 0.14 per cent, according to University College Cork researchers.
Successful schemes have been run in many other countries, such as the US and UK, which saw an 85 per cent reduction in the use of single-use bags.
The fact that 70 per cent of people support the move (according to research firm Canstar Blue) means there is enormous goodwill from shoppers.
People can’t or won’t take their own bags to the supermarket: Again, this is not true. Regular shoppers at overseas giants like Aldi, Bunnings and Ikea either go without bags, bring their own or buy a smaller number of heavier re-usable bags.
Bunnings started charging for bags in 2003. They hoped for a drop of 50 per cent, but five years later, plastic bag use was down by 99 per cent.
Similarly, a trial in 16 Coles, BI-LO, Safeway, and IGA supermarkets in Narre Warren, Wangaratta and Warrnambool found a 10c levy led to an 80 per cent reduction in bag use.
The Canstar Blue survey of 2200 people nationally said people thought it would be a hassle initially, with many people starting to stockpile bags to reuse.
Single-use bags are used again and again: Some argue single-use bags are a misnomer because people use them again and again. That is also wrong. Some studies have found people have 30 to 40 plastic bags stashed away in their kitchens or laundries, most of which they will throw away without reusing.
While some are used as bin liners or rubbish bags, the vast majority of the 300 or so bags people use a year are thrown away. Clean Up Australia says plastic bags make up 13 per cent of our litter.
Plastics aren’t a problem in our country: Woolworths gave out more than 3.2 billion single-use bags a year, and about 50 million end in the oceans and rivers where they cause pollution and harm whales, birds, seals and turtles.
Just because there are other countries with a worse pollution problem than us doesn’t change the fact that we need to do more.
With China refusing to take waste from other countries such as ours, the environmental impact from plastic bags is only going to increase over time.
University of Technology, Sydney researcher Jenni Downes says the main effects of plastic bags are the fossil fuels used during production, marine litter and contamination of other recycling products.
However, improvements could be made to the plastic-bag bans.
Overseas, people had to pay for the lighter bags, not the more durable ones, which need to be used four times to obtain any environmental benefit.
There is also a legitimate concern about the windfall for supermarkets, which stand to gain about $70 million a year from the sale of bags.
In most other countries, proceeds from bag sales go to environmental funds and are redirected into educational campaigns.
There is no doubt ongoing education of shoppers is necessary.
Education does work, because most people want to do the right thing by the environment by using less plastic that takes a lot of energy to produce, is used only once and takes years to decompose.
The success of the plastic bag ban isn’t up to the retailers, it’s up to the shoppers – us. If people refuse to change their behaviour, it will be a costly failure. In that case, the only winners will be the supermarkets – and the climate change deniers who have been opposed from the start.
