Globally, glass manufacturing emits at least 86 million tons of carbon dioxide annually. However, a new type of glass called LionGlass, developed by Penn State researchers, offers the potential to reduce this carbon output by 50%.

researchers, offers the potential to reduce this carbon output by 50%. Not only does this innovative glass demand considerably less energy for production, but it also boasts greater resistance to damage compared to conventional soda lime silicate glass. The scientists behind this breakthrough have recently submitted a patent application, marking the initial move towards introducing LionGlass to the market.
“During the glass melting process, the carbonates decompose into oxides and produce carbon dioxide, which gets released into the atmosphere,” Mauro said. Some of the team’s glass compositions had such a strong crack resistance that the glass would not crack, even under a one kilogram-force load from a Vickers diamond indenter. LionGlass is at least 10 times as crack-resistant compared to standard soda lime glass, which forms cracks under a load of about 0.1 kilograms force. The researchers explained that the limits of LionGlass have not yet been found, because they reached the maximum load allowed by the indentation equipment.
“Damage resistance is a particularly important property for glass,” Mauro said. “Think about all the ways we rely on the strength of glass, in the automotive industry and electronics industry, architecture, and communication technology like fiber optic cables. Even in health care, vaccines are stored in strong, chemically resistant glass packaging.”
