Unusual Olympics: What makes Tokyo 2020 different

Tokyo 2020 will be the first to build an Olympic Village using renewable materials, adopting the concepts of "reduce", "reuse" and "recycle" as one of the leading themes of the Olympic Games, reflected in many aspects of the event.

Paperboard beds stand out among the achievements. More than 100 podiums are made of waste household plastics, and the raw materials for making these podiums were collected by more than 2,000 brand chain stores in Japan. Gold, silver and bronze medals are made from recycled mobile phones.

The buildings at the Olympic Village Square, which are made of wood, will be disassembled and transported back to their "hometowns" for reuse after the Games.
