Abstract
Float glass is a largely unexplored material flow in the context of circularity. As the Dutch government wants construction to be fully circular by 2050, new ways have to be found to deal with float glass. Five scenarios for sustainable glass handling are discussed: what would happen if all available secondary windows would be recycled, remanufactured, reused, repaired, or if glass use would be reduced? The effects on material demand, energy use, value chain processes, and product are explored and compared. Finally, policy options are proposed to stimulate these sustainable strategies.
