I believe I know where the space-age fill used in the My Pillows comes from. If you've seen the commercials, you will notice they briefly show what looks like some sort of industrial foam shipping containers, or insulators.
This material is more than likely from shipping aircraft parts, and is not reusable, or cannot be disposed of by normal methods. Instead they shred it, and repurpose the material for the fill in the pillows.
I'm not sure of this, but it seems logical to me, or why would they show that clip in the commercial? One man's trash, is another man's treasure.
