For (at least some of) the CES attendees who feel conflicted regarding whether or not their plastic (in all probability single-use) bottles will actually be recycled or not; Ford Motor Company plans to use (whilst still a small number) post-consumer bottles in the production of their Ford Focus Electric (a harbinger for hopefully a lot more uses of said material in a wide-range of products in the present and future).
