content: I can answer part of the cell phone issue, we store tons of our lives on it and many are leery to hand that over to someone the is collecting cell phones. Trash isn't better but it is hidden in with other stuff not just a bin full of cell phones, or we keep them around the house on a shelf for a few years then pitch them when cleaning.  On the bottle side you are dead right glass to glass is better then glass to sand to glass, and yes the places that would do this would just recycle it anyhow.
