Medali Olimpiade Tokyo 2020

Tokyo 2020 membuat medali emas, perak dan perunggu seluruhnya menggunakan 78,985 ton dari daur ulang komponen elektronik, termasuk 6.21 juta telepon seluler, menurut the Tokyo 2020 Medal Project.

Ternyata, dari semua komponen elektronik tersebut mengandung semua bahan yang cukup untuk keperluan pembuatan 3 jenis medali tersebut. Tidak disebutkan apakah pita yang dipakai juga berasal dari material daur ulang, namun sepertinya menggunakan plastik daur ulang bisa juga.

Dari sekitar 80,000 ton material daur ulang dari gawai, hanya diperoleh sekitar 32 kg emas, 3.500 kg perak dan 2.200 kg perunggu (dalam hal ini tembaga dan besi) yang bisa diekstrak.

The Tokyo 2020 Medal Project — termasuk di dalamnya operator seluler Jepang NTT Docomo, yang mengumpulkan telepon seluler bekas tersebut — memulai proses pengumpulan sejak bulan April 2017 sampai Maret 2019. Dari periode dua tahun pengumpulan tersebut, dapat dikumpulkan material yang cukup untuk membuat sekitar 5,000 medali untuk Olimpiade dan Paralimpiade Tokyo 2020.
