One man's trash is another man's cell-phone materials. That, at least, is the philosophy behind Nokia's Remade mobile device concept. Nokia revealed the Remade concept at the Mobile World Congress conference in Barcelona. The idea is to assemble mobile devices made from nothing new, according to Nokia.

The idea is to assemble mobile devices made from nothing new, according to Nokia. “It has been designed using recycled materials that avoid the need for natural resources, reduce landfill, and allow for more energy efficient production,” per the company’s description on the Nokia Web site. The phone would be made from recycle aluminum cans. The chassis materials would come from plastic drinking bottles. The rubber key mats would be made from old car tires. “Inside the phone are new more environmentally friendly technologies such as printed electronics, and the graphics used on the display save energy without compromising on style,” according to the company. The company also alludes to a “no-waste charger” — presumably one that stops drawing energy from the wall socket once the device is charged.Nokia isn’t clear yet as to when it might transform the Remade concept into a commercial product.
