TRE Glass Corporation is a Japan-based subsidiary of TRE Holdings that specializes in the recovery and processing of waste flat glass. The company focuses on converting end-of-life architectural and window glass into high-quality cullet suitable for remelting, supporting closed-loop, “horizontal” recycling within the glass supply chain.
Its operations typically include collection coordination, sorting, disassembly, crushing, and rigorous quality control to meet specifications required by glass manufacturers. By supplying specification-compliant cullet, TRE Glass helps reduce landfill disposal and enables lower-energy glass production through higher recycled content. The company serves stakeholders across the construction and demolition ecosystem as well as glass producers seeking stable, quality-assured recycled raw materials.
