Hitachi, Itoki, and Tokuyama, aiming to realize a resource-circulating society, have demonstrated the upcycling of plate glass recovered from solar panels, a waste-prone issue, into furniture components.
Specifically, Tokuyama’s low-temperature pyrolysis method recovered high-quality plate glass, and Hitachi’s non-destructive strength estimation technology assessed the effects of degradation such as cracking and alkali leaching, enabling the glass to be reused as is.

In addition, Itoki prototyped a conference booth that utilized the unique characteristics of the recovered plate glass, proposing new value for recycled materials. This will promote the creation of sustainable spaces in offices and public spaces that combine environmental friendliness and beauty.

This initiative demonstrates the reuse of plate glass recovered from solar panels into office furniture without shredding. In addition to reducing waste, it is expected to reduce CO2 emissions by up to 50% compared to manufacturing new glass, supporting the development of sustainable social infrastructure.
