Tokyo wants to make Olympic medals from old smartphones
16 February 2017 | 0
In the case of a smartphone, there’s about 0.048 grams of gold, 0.26 grams of silver, and 12.7 grams of bronze. To make the roughly 5,000 medals that will be awarded in 2020, organizers will need 10 kilograms of gold, 1,230kg of silver, and 736kg of bronze. (The amount of gold is much less because those medals are plated and not solid gold).
The campaign is asking citizens to turn in used smartphones, digital cameras, video cameras, audio players, portable game devices, remote controls, electronic calculators, GPS units, and AC power adapters.
While the project will begin small with a single collection point at a convenience store in the Metropolitan Government building, it will go national in April when consumers will be able to donate used gadgets at 2,400 shops of mobile phone carrier NTT DoCoMo.
