Checking out at the supermarket recently, the young cashier suggested I should bring my own bags because plastic bags weren't good for the environment. I apologized and explained, “We didn't have this green thing back in my earlier days“.
I don't want to side track this debate, but I will, the 'green' credentials of 'green bags' really have a lot to live up to. I don't think anyone has seriously ever done a proper environmental life cycle for them given realistic terms of use, not the "yeah each bag will last 2 years of use"...like **** it will hahaha, I see at least 3 in the bins at my apartment block a week.
Some food for thought.
-They are still plastic and contain a shirttonne more plastic than the humble plastic bag which contains so little plastic these days it basically falls apart when you pick something up in it
-They are massively labour intensive to produce compared to a plastic bag
-They are made in China so have to be shipped here
- What do you line your bin with now? buy plastic bin liners?
The only way they come out ahead is if you use one green bag to carry groceries as many times as the weight ratio difference between one green bag and one plastic bag, where the weight ratio of the green bag has the weight of any bin liner bags used added to it. I find it hard to believe anyone actually achieves this; I don't know how many plastic bags = 1 green bag by weight but i'd guess it would be a lot. This also doesn't factor in the disparity in energy required to produce each item.
Then there's the bin liner question, my 'bag store' is basically in a constant state of equilibrium as I use bags received from the previous weeks shop to line the bin, as they are used they are replace by bags from the next shop etc etc. Coles and Woolies apparently sold about 17 million of them last year, they buy them for about $0.60 apparently and sell them for $0.99, that's a cool 6.6 mill for 'doing the environment a favour'...pull the other one.
So end of the day I would have looked at the cashier with "are you taking the piss" look and said, "nah give me the plastic bags thanks"
