Most old window glass doesn’t get recycled into new window glass, instead it typically gets used in lower grade applications such as packaging and aggregates. In a future where high-performance windows and doors are vital to deliver energy efficient and comfortable homes, the ability to remanufacture the glass from old windows is essential. Saint-Gobain Glass is pioneering the collection and re-processing of end-of-life window glass, taking old poorly performing glass, and remanufacturing it into new high-performance glass for new high-performance windows. This saves energy, reduces the need to extract raw-materials, and lowers the embodied-carbon of glass. Michael Butterick, Marketing Director of Saint-Gobain Glass, will explain how Saint-Gobain is working to deliver a sustainable closed-loop process for window glass.
