We visited Professor Hiroya Tanaka’s Recycling Lab at Keio University in Kamakura and heard about the latest trends in resource circulation and the circular economy.
At the lab, collected plastic waste is upcycled with a 3D printer into items such as chairs, benches, and exhibition fixtures.
Professor Tanaka is in charge of the Japan Pavilion at Expo 2025 Osaka, Kansai, and has been developing the exhibition theme for about five years.
Chairs made from recycled plastic have also been adopted as hands-on exhibits in the pavilion, allowing visitors to touch them.
Afterwards, we visited Kayac Inc., a nearby company, and experienced a “zero-waste” lunch using reusable containers. In the afternoon, we formed mixed teams with one participant from each country and strolled around Kamakura, visiting famous spots and backstreets, deepening our interactions and quickly becoming close.
