This study evaluates the environmental impact of scaling up the reuse of post-consumer glass through a process-based Life Cycle Assessment (LCA). By analyzing key parameters such as material recovery rates, energy consumption, and transport distances, the study identifies critical hotspots in the reuse preparation process. Results highlight the importance of optimizing glass sorting and minimizing transport emissions to enhance sustainability. While challenges remain, particularly with coated glass panes limiting recovery yields, findings suggest that strategic improvements in processing efficiency and logistics can significantly reduce environmental impacts, supporting glass reuse as a viable circular strategy in construction.
