The use of finely ground waste cathode ray tube (CRT) glass as a partial replacement for cement directly links the principles of circular economy with the reduction of carbon dioxide emissions. Instead of ending up in landfills, glass is returned to the production cycle as a pozzolanic material, reducing the need for extracting natural resources and producing clinker—the most carbon‑intensive component of cement. Since manufacturing one ton of clinker emits roughly 800–900 kg of CO₂, replacing up to 35% of cement with glass powder can lower the overall carbon footprint of concrete. This study examined concrete in which up to 35% of the cement was replaced with glass powder finer than 63 microns, demonstrating how turning waste into a valuable material directly supports climate benefits and the core principles of the circular economy.
