Glass Recycling

Is all glass recyclable?

Most types of glass are recyclable, including clear, brown, and green glass bottles and jars. However, not all glass can be recycled due to its composition. Some types of glass, such as tempered glass, ceramics, and Pyrex, are not suitable for recycling because they have different melting temperatures or chemical compositions that make them difficult to recycle.

Glass recycling is the processing of waste glass into usable products. The industry term for furnace-ready recycled glass is “cullet.” Glass cullet is classified in sizes that can range from pebbles to sand and even powder.

Common non-container uses

• Fiberglass manufacturing
• Abrasives
• Binder in ceramics and bricks
• Filler in paint and plastic
• Filtration media

How glass is recycled

The process for recycling glass typically involves several steps:

• Collection - Glass bottles and jars are collected from homes, businesses, and other sources. The glass is then transported to a recycling facility.
• Sorting and washing - The glass is sorted by color and washed to remove impurities. The glass is also carefully inspected for contamination and hazardous materials.
•  Crushing and melting - The glass is then crushed and melted. Furnace-ready cullet must be free of contaminants such as metals, ceramics, gravel, stones, etc. The glass is then molded into new products such as bottles and jars. Or it may be used for alternative purposes such as brick manufacture or decorative uses.
• Forming: The melted glass is formed into new glass containers, such as bottles and jars, using molds.
• The glass is then sent back to the shops, ready to be used again.

Where can I recycle glass?

Many communities include glass bottle and container collection in curbside collection programs. Outside of curbside collection programs, there are other several places where you can recycle glass, including:

1. Drop-off centers: Many communities have designated recycling drop-off centers where you can bring your glass for recycling. These centers may be operated by the local government, private companies, or non-profit organizations.
2. Retail locations: Some retailers, such as grocery stores, may have glass recycling bins where customers can drop off their glass bottles and jars.
3. Schools and offices: Many schools and offices have recycling programs in place, where you can drop off glass to be recycled.
