For the upcoming 2020 Olympic Games, which are to be held in Tokyo, Japan, it has been proposed that recycled metal from electronic waste should be used to create the gold, silver, and bronze medals that will be awarded to athletes from around the world. This work is aimed at exploring the feasibility of this goal, quantifying the required electronic waste, identifying the limiting material constraints, and addressing a selection of sustainability metrics. The results show that 2.5-13.8% of Japan's available electronic waste would be required to create the medals, depending on the composition of the collected electronics and the processing yields. The environmental benefits from this venture are identified as being a savings of approximately 4.5-5.1 TJ of energy, which is equivalent to CO2 emissions reductions of approximately 420 metric tons. Additionally, qualitative potential benefits to environment, human health, economic recovery of valuable materials, and supply stability are considered.
