I've never known a discarded beer bottle to start a fire (not saying it's impossible) but I have seen it happen with a clear bottle full of water. SA has had a container deposit system in place, working very well for donkey's years. One by one some of the other states have been dragged, kicking and screaming, to the same conclusion (that it works). I have always thought there was a bit too much "pride" involved (can't be seen copying something SA did, now can we??)
