Glass Takes Million Years To Decompose

At its core, glass is essentially liquid sand, superheated and then rapidly cooled into a stable, solid state. Composed primarily of silicon dioxide, the same compound found in quartz, glass is incredibly inert and resistant to chemical change. Unlike organic materials, microorganisms don't recognize it as a food source, so it doesn't biodegrade or rot away. The million-year timeline for its "decomposition" refers to the immense time it would take for physical weathering—the slow grinding by wind and water—to break it down into tiny, sand-like particles, much like a natural rock. This is why glass artifacts from ancient Roman and Egyptian civilizations can still be found intact today.

This same incredible durability, however, is what makes glass a perfect candidate for recycling. Because glass doesn't lose its chemical integrity, it can be melted down and reformed into new products endlessly without any loss of quality. This process requires significantly less energy than creating virgin glass from raw materials like sand and soda ash, which must be heated to extreme temperatures of around 1700°C (3090°F).
