A disingenious article, on two counts:

1. "waste isn't a problem yet": yes it is. Mining tailings for example are a real problem. So is air pollution from making them (all PV factories are powered by coal plants). Of course, since this happens in China, it doesn't exist, right?
2. It's a research level setup, not a commercial recycling plant. Wake me when we get to that stage please.
