Re: Does anyone remember?
I think bringing it back would be a good idea.
Add a penny or two to the cost of a bottle of pop (or whatever) and offer the same for the return of the empty bottle - plastic bottles as well as glass.
Plastic bottles could be recycled, as now, and glass bottles could be cleaned and sterilised for re-use, assuming that this is still an economically viable alternative.
Most adults wouldn't bother, of course, but young kids might be quite happy to collect empty bottles as, indeed, did we. I am, as some of you may already know, all in favour of child labour. The Victorians had the right idea.
