Here’s Sony Ericsson’s GreenHeart concept. The handset was made using bio-plastic casing and keypads that can be easily recycled. The GreenHeart even comes bundled with a new charger that is smart enough to turn itself off when the phone is fully recharged. Environmental concerns even extend to the user’s manual which is entirely HTML-based to save paper, thereby saving trees. Add in environmentally conscious packaging, and some hippies might let go of the tree they’re hugging in order to get one. The Sony Ericsson GreenHeart is only a concept, but it shows a new greener direction.
