There is a common misconception about recycling glass, believing that all glass items, such as cups, light bulbs, and windows, can be recycled along with bottles and jars. However, recycling companies do not want these items because they are treated differently, especially windows.
Windows are made of treated glass, which is much harder to break than glass bottles. The process for recycling glass involves melting it in a furnace, but treated glass requires a higher temperature to melt. If window glass is mixed with container glass, it contaminates the entire batch. Recycling facilities are not typically equipped to recycle windows due to the different processes involved.
If you have old windows, consider donating them for reuse at places like Habitat for Humanity ReStore. Or repurpose them for DIY projects like bulletin boards or jewelry organizers. If you need to replace your windows, look into options for recycling them as construction and demolition waste.
Companies like SolarWindow even offer technology to turn windows into solar panels, providing an eco-friendly upgrade option. Just be mindful of handling broken windows, as they are less valuable in the recycling market and pose safety risks.
