“Is it recyclable?” Episode 2: BROKEN GLASS

Glass is made from heating sand to an extremely high temperature with other minerals to form a material that is ideal for a wide range of uses. In fact, molten glass can be manipulated to form packaging, car windscreens, glazing or numerous other products. Glass recycling helps the environment as reduces the energy needed to melt the ingredients for new glass, and reduces CO2emissions (each tonne of raw materials replaced by recycled glass saves 246kg of CO2emissions).

If container glass (bottles and jars) is 100% recyclable, unfortunately, broken glass is NOT recyclable. Firstly, for safety reasons as it can cause injury to the collection crew orworkers at the material recovery facility (MRF). Secondly,not all glass is the same. For example, drinking glasses, Pyrex and window glass only melt at much higher temperatures than glass bottles and jars. Light bulbs usually contain small amounts of mercury that make them unsuitable for reuse at a MRF.

Broken window and mirror glass can still be repurposed: some facilities convert it into building materials, fiberglass and asphalt.
