I suspect it just moves the waste, and perhaps more, to the home.

If you now have to buy a kilo bag, instead of the few you think you'll need for the next week or two, you'll probably be throwing some deteriorated produce along with the plastic bags.

For onions and spuds plastic is a poor choice anyway as they should be able to breathe. Better still, unwashed, as with carrots. Why, oh why, do supermarkets insist on washing off natural protection?
