Does it? Or is there some other economic penalty involved to make it work? Or do they just think it works, and it goes the places our recycles go?
I really don't know the answer to that, and am curious.
Beer bottles in Germany are much heavier (made of thicker glass) for durability. They go back to the brewery and are used over and over. A bottle can be reused for many years.
Here is a typical bottle washing machine in a Munich brewery. It does 60,000 bottles per hour, and there are usually a few of these in operation at one time. It may sound funny, but these are very high tech machines.
