The federal government in Canada is about to start phasing in a nationwide ban on plastic bags. Many individual businesses, municipalities, and at least one province have already done so.
I’m as environmentally conscious as anyone, and I make good use of my nice insulated reusable grocery bags. But when they aren’t enough, I do collect the odd plastic bag now and then, and I use them to line the kitchen garbage pail. All my garbage goes out in used grocery bags. None ever get thrown out as garbage by themselves. If I didn’t use grocery bags for this, I’d simply have to buy plastic bags for that purpose.
Anyway, here’s a CBC article about the effect of Walmart’s ban on plastic bags. This is the money quote (emphasis mine):
When Walmart banned single-use plastic checkout bags in April, customer Larry Grant applauded the move — until he found himself drowning in reusable bags.
Each week, Grant orders Walmart groceries for pickup at a depot near his home in Toronto. Due to the plastic bag ban, the retailer now packs his items in reusable bags — new ones for each order.
Grant estimates he has acquired about 300 over the past six months.
“It’s a bit crazy,” he said, pointing to a large pile of blue Walmart bags stuffed in the trunk of his car. “In a month, I can be accumulating anywhere from 40 to 50.”
Of course this can just be attributed to idiotic policy at Walmart, but it does show that the ban is more about public relations and saving a few bucks than anything to do with the environment. The only difference between the “reusable” new bags and traditional plastic bags is that the new ones are thicker and heavier and use much more plastic, cannot be reused for garbage or doggie-poop pickup, and are ultimately more damaging to the environment when thrown away.
The real solution to the plastic bag “problem”, if indeed it’s a problem at all, is to reuse or recycle them responsibly, and potentially to make them out of biodegradable plastic. There already are such bags sold for use as “green bin” liners, for kitchen waste that is used for composting.
