Did you know that glass is 100% recyclable and can be recycled endlessly without loss in quality or purity? Glass is an ideal material for recycling and where it is used for new glass container manufacture it is virtually infinitely recyclable. The use of recycled glass in new containers helps save energy. It helps in brick and ceramic manufacture, and it conserves raw materials, reduces energy consumption, and reduces the volume of waste sent to landfill.
Not only is glass recycled to make more glass, its also become a popular aggregate for various construction applications. Here’s more from Wikipedia:
- Glass in insulation products
- Glass in ceramic sanitary wast production
- Glass in astroturf and related applications
- Glass in recycled glass countertops
- Glass as an abrasive
- Glass as an aggregate
Glass aggregate, a mix of colors crushed to a small size, is substituted for pea gravel or crushed rock in many construction and utility projects, saving municipalities thousands of dollars (depending on the size of the project). Glass aggregate is not sharp to handle. In many cases, the state Department of Transportation has specifications for use, size and percentage of quantity for use. Common applications are as pipe bedding—placed around sewer, storm water or drinking water pipes to transfer weight from the surface and protect the pipe. Another common use would be as fill to bring the level of a concrete floor even with a foundation.
But maybe more importantly, glass is made from readily available domestic materials, such as sand, soda ash, limestone and “cullet,” the industry term for furnace-ready scrap glass. The only material used in greater volumes than cullet is sand. These materials are mixed, or “batched,” heated to a temperature of 2600 to 2800 degrees Fahrenheit and molded into the desired shape.
