The medals which will be used in the next Olympics, to be held in Tokyo, will be made out of recycled mobiles and gadgets, according to the organizers.

Tokyo is set to host the Games in 2020 and this step will make the competition a more environment friendly edge. 

"Medals made with recycled metals from discarded mobile phones and other gadgets can be a symbol of sustainability and public participation," spokeswoman Hikariko Ono told reporters.

Although, Ono added, that whether some or all medals will use recycled material will be decided later on.

Ono further said that the Games have been using recycled material for medals since the Vancouver Winter Olympics since 2010. Even this year’s Rio Olympics used recycled metal Gold and Bronze medals.

The cost efficiency of these medals remains unclear though. According to experts, the total budget of the Games could reach USD 30 billion - four times the initial estimate and almost triple that of the 2012 London Olympics.
