Now this is hardly shocking news - if the SA Government paid attention to overseas examples (E.g. Ireland), then they would have easily been able to foresee this result - that plastic bag bans result in increased bin liner usage.
It will be interesting to see if there is a change in policy, should there be a change in Government at the next South Australian state election - as the Coalition opposition had described the policy as "tokenistic".
According to the Adelaide Now newspaper: "BIN liner sales in SA have doubled since free plastic shopping bags were banned more than two years ago. And most bin bags are made of thicker plastic than traditional bags, which means they take longer to break down in the environment. Woolworths says SA sales of plastic kitchen-tidy bags of a similar size, capacity and shape to single-use plastic shopping bags, are now double the national average.At Coles, sales of kitchen tidy bags increased 40 per cent in the year following the ban in May 2009. Bin bag manufacturer Glad reported a 52.5 per cent jump in kitchen-tidy bag sales in the first year of the ban, compared with a 5.5 per cent increase nationally… In 2009, South Australia led the nation with a ban on lightweight, checkout-style plastic bags."
