AGC × ReLink: Glass Upcycling Workshop in Suwa
Touching glass, entering the community, searching for a point of contact with circularity
Glass, which should be recyclable almost indefinitely, is discarded in enormous quantities. In this workshop, co-hosted by AGC and ReLink, participants reframed glass headed for disposal as a resource, experiencing the process of melting and shaping it with their own hands. Glass doesn't melt or take shape the way you expect — participants adjusted temperature and pressure by feel, failing again and again while slowly building skill. The workshop became a chance to think about the kind of place a workshop is — one that supports this patient trial-and-error and curiosity — and about the shift from owning things to circulating them, layered together with the ideas of reuse and sharing.

How to Design a Glass Recycling System
Glass is a material that can be remade as many times as needed when melted. Even glasses and vessels that have taken on a specific form can be reborn into a different shape by applying heat again once they are no longer needed.This property challenges our conventional image of what we have come to call “trash” or “unwanted items.” Discarded glass is not the end; it is merely a “temporary” state on the way to its next form.
In this workshop, organized in collaboration with AGC, we redefined glass destined for disposal as a resource and, through the process of melting and shaping it with our own hands, reexamined what it means for an object to be “complete.” Glass does not melt as easily as one might think, nor does it take shape as easily as one might imagine.By adjusting the temperature and the amount of force applied through trial and error—trying again and again, failing, and gradually mastering the technique—participants learned step by step. It was precisely this steady process of experimentation, supported by curiosity, that gave life to the workshop space. Rather than creating with a final form in mind, the attitude of treating the materials at hand as a provisional state that can be reconfigured at any time aligns with the concepts of reuse and sharing.How can glass circulate more richly within the community and people’s daily lives? I would like to envision Suwa as a “space centered on glass” and, beyond that, as a “glass-circulating city.”
The act of remelting glass is not merely a technical practice of recycling. It was an experience that, through hands-on experimentation, confirmed the sense that neither objects nor people inherently possess a “final form”—that everything exists within a provisional arrangement.
