Sonys Green Mobile for Future.

Sony's Green Mobile for Future.

The Sony Ericsson Greenheart Concept phone was spotted at a Sony event last week in Copenhagen.

The Differentiator:

bio-plastic shell, HTML-based manuals, a recycled plastic keypad and an energy-efficient charger that uses only 3.5 mW of power during standby.In comparison, most efficient cell-phone chargers use 30 mW on standby.

With the warranty, the phones can be recycled anywhere in the world if brought to designated drop-off areas. Currently, there are over 500 drop-off areas, and Sony plans to add more in the future.
