I agree - a complex question - and a difficult one for retailers to balance customer expectations with economics and efficiency.
Choice answered the question for me regarding the “re-usable” green bags (sold for $1.50 - $3) which seem to last less than a year before tearing - I wouldn’t get enough use to justify them.
The Queensland ban came into effect 1st July 2018. My small supermarket (more a convenience store, but the only store in town) started selling their single use bags for 10cents each, 2 months before the ban took effect. They suffered loss of trade as a result. They now have boxes free and re-usables for sale.
The takeaway just changed to the thick bags - why? - the chips or chicken pieces are already boxed. Again, consumer expectation, they always got it in a bag.
The bulk supermarket we use for the majority of our shopping has boxes on the shelves, so it is easy to grab a box full or empty and fill. After your trolley is filled they offer bags, but we have always refused as we carry the car fridge, foam & cardboard boxes, their boxes and old plastic bags in the car.
I can sew, and have made rough bags from old clothing (our clothes wear out, we don’t ditch for fashion) and made tulle bags for vegetables in store. Tulle is that netting ballerina’s tutus are made of and I took advantage of a sale to get it for $0.84/m. Environmentally tulle is plastic, but it lasts a LONG time, but there is good & bad in that.
I am old enough to remember paper bags at shops, but they can’t handle condensation on cold goods. I used to clean up a section of highway leading into town, single use plastic bags and drink bottles proliferated with plastic bags hard to get out of prickly acacia. I am happy to see them go.
I am still running into people who demand single use bags because they feel that something has been taken away from them, they abuse the check-out staff and rant to mates, none of whom are responsible or can change it.
Any bags we have are used many times, the cardboard, when no longer holding together as a box, is composted. We don’t have money and we don’t have a garbage service, so that dictates our use of resources.
