Not only Nokia Remade is the only phone concept but a new Biodegradable Concept cell phone called “Bamboo” is entering in the Greener Gadgets Design Competition 2008. This is a bio degradable cell phone concept designed as a nature-friendly phone. The casing is made of bio-plastic made of renewable natural resources like Corn and Bamboo, which, when harvested, grows back in due time.
Even, after a year or so and you decide not to use the phone anymore, you can bury the print board, battery, and antenna in compost, which will then disintegrate, releasing bamboo seeds that would grow into new plants. The phone will also feature an energy-efficient monochrome display, and a hand-crack with which to re-charge the phone. A 3-minute cranking session could provide enough power for one phone call.
