closing the loop

Previously we’ve discussed how the Tokyo Olympic and Paralympic Games are to make a statement on sustainability by salvaging precious metals for the placing athletes from electronic waste, and now courtesy of Dezeen, we see the committee has revealed their gold, silver and bronze medals.
Designed and conceived by Junichi Kawanishi, the medals and their cases are alloyed from substances recovered from old electronic devices donated by the public. All told, this netted—mostly from obsolete smart phones, some six million of them over the course of two years—thirty-two kilogrammes of gold, thirty-five hundred kilogrammes of silver and twenty-two hundred kilogrammes of bronze.
