There used to be a law in canada that all the beer brands had to use the same bottle, and you paid deposit when you bought the beer, which you got back when you returned them to a bottle place. The bottles were cleaned and re-used multiple times. When the deposit was first introduced it was a reasonably amount and so people would always bring them back, and if they didn't kids would find them and do it for you. Some staggering figure like 90% of beer bottles were re-used. This has changed as the beer bottle requirements got softened, more imports with no re-usable bottles, and the inflation making the deposit worth much much less to the point its not worth it for many to bother with it. Perfect example of a system that worked really well, but was weakened and was corrupted over time because neglect.
