Nokia shows off Green Phone

Plastic from drink bottles form its chassis while its rubber keypad is made from old car tyres, Nokia said in a statement.

Called "Remade", the silver-coloured handset is a concept that "explores potential new ideas", the company said.

"The idea behind the concept was to see if it was possible to create a device made from nothing new.

"It has been designed using recycled materials that avoid the need for natural resources, reduce landfill, and allow for more energy efficient production," Nokia said.

Remade is part of Nokia’s ongoing environmental effort.

"It is designed to help inspire and stimulate discussion on how mobile devices might be made in the future," according to the phone maker.

Olli-Pekka Kallasvuo, the Finnish firm's chief executive, pulled the clamshell handset out of his pocket during his speech at the Mobile World Congress trade show in Barcelona yesterday, pictured above. "It shows what can be done with materials," he said. "It is only a concept now but it gives you an insight into how we think we can break new ground." Nokia, which last year made four in 10 of the more than 1bn handsets sold worldwide, has been developing the handset - branded Remade - at its laboratories.

The metal casing and keypad are made from recycled steel, while inside the phone Nokia has been working on materials with an organic origin, such as polylactic acid plastics.
