How is Glass Recycled?
Here’s a breakdown of how glass is recycled:
Colored glass containers are created by adding a coloring agent that cannot be removed. This means that colored glass, such as green and brown glass, can only be used to produce new green and brown glass, respectively.
- Separation of Contaminants: Any glass that has been contaminated by color mixing or other contaminants can be used to insulate fiberglass or as an ingredient in concrete.
- Cullet Creation: Cullet is crushed glass. It is created by melting down bottles and jars in a furnace. Any paper labels left on the glass will be burnt off, but metal lids are removed so they do not harm the furnace. Cullet melts at a lower temperature than raw ingredients (such as sand), and is used to make new glass. Significant energy savings are achieved in this process.
- Reformation: Cullet serves as the main ingredient in new glass containers. The melted cullet is molded into the desired shape, such as a a bottle or jar, with the end product back on the shelves within 30 days of the original glass container being recycled.
