Teijin to showcase world’s first bioplastic pipe organ at Expo 2025 Osaka

The bioplastic pipe organ was developed by a consortium of eight plastic molding companies

Teijin Limited announced that pipes made from its biomass-derived polycarbonate (PC) resin have been chosen for use in the world’s first pipe organ constructed entirely from bioplastic. The transparent pipes were produced by Teiyo Co., a Teijin Group company specializing in plastic molding. This groundbreaking pipe organ will be showcased in the “Reborn Challenge” area of the Osaka Healthcare Pavilion at Expo 2025 Osaka, Kansai, Japan, from August 19 to 25.

The bioplastic pipe organ was developed by a consortium of eight plastic molding companies participating in the “REBORN with Bioplastics” project, organized by the West Japan Plastic Products Industrial Association. It symbolizes how the plastics industry’s technologies and innovations can help address global environmental challenges such as climate change and marine plastic pollution.

At the request of the consortium, Teiyo manufactured the plastic pipes for the organ using biomass-derived polycarbonate (PC) resin produced by Teijin through the mass balance approach. Beyond the sustainability advantages of the biomass-derived PC resin, Teiyo’s advanced molding technology—which allows for the production of pipes in various lengths and diameters—was a key factor in their selection for this project.
