Meh - this whole thread is backwards. Denmark, Germany etc have water that comes in thick plastic bottles that are cleaned and reused multiple times. What's the point in recycling something that could be reused? The deposit on plastic bottles in the US (even in those states that have them) is way too low, and supermarkets get away with putting recycling machines that function 2 hours away down piss-soaked alleys. As a result, taking bottles back for the deposit in the US is pretty much the shameful reserve of vagrants and the terminally tight-fisted (I'm the latter).

A 25c deposit on every bottle would drastically reduce waste/litter, and improve re-use. Of course, there's zero political support for it...
