Rethink Hanger uses plastic bottles to hang clothes. Imagine cutting down on plastic entering the waste stream and at the same time making something useful for yourself. This contraption allows you to screw two bottles into a plastic hook creating an item thatis in need.

The unit will cost 8 dollars per hanger, which is quite a nut to crack when you consider trying to fill a closet. Also you need to consider the extra room the bottles would take up over the dread wire hangers. If there was some way to melt or flatten them slightly this would be a fantastic idea.
