In general I realized that most clean tech is difficult to recycle at this point, from this site[1]. I'm just trying to get the big picture, and hoping that we don't solve one problem by creating the next. In the end our waste ends up in the environment and in our food.

1. You are quite possibly right. Do you have a source supporting that the expected industrial waste is in the kilotonnes range? I'm not arguing it is not, I don't know.

2. It's just something that occured to me recently. It's not that just these things have to be recycled. It would be best if we did something about waste too.

3. and 4. Thanks for the link!
