Mobile phone giant Nokia has this week unveiled a new handset made entirely from renewable and recycled parts, although it is unclear if the concept phone will ever be made available to customers

The "Remade" phone is being developed in Nokia's labs and was shown publicly for the first time this week by chief executive Olli-Pekka Kallasvuo in his keynote speech at the GSMA Mobile World Congress in Barcelona.

The phone's casing and keypad are made from recycled steel, while Nokia plans to make the internal components from organic materials, such as polylactic acid plastics.

The device does not yet make calls and the company said it has not yet decided if it will manufacture the phone. However, Kallasvuo said the design showed what could be achieved with genuinely sustainable materials. "It is only a concept now but it gives you an insight into how we think we can break new ground," he added.

The new design comes hot on the heels of the launch late last year of the Nokia 3110 Evolve, which features "bio-covers" made from 50 per cent organic material and comes with an energy efficient charger that uses 94 per cent less power than that required under the Energy Star specifications.
