After studying Chemical Engineering at the Technical University of Eindhoven, the Netherlands, Tom started working as Sales Engineer at Innov-X Systems. He initially focused on selling handheld XRF equipment in the Benelux, while gradually extending the geographical territory over the years. From 2007 he was heavily involved in the pioneering of automated XRF sensor technology, bringing this new technology to the metal scrap market worldwide. Tom joined TOMRA Sorting (then Titech GmbH) in 2011 as Sales Manager responsible for the Metal Recycling market in the Netherlands and Belgium. Since then, in his role as Segment Champion for the ELV shredder segment, he has also supported the metal recycling market in the Middle East region, Italy, Greece and projects in several other countries.

Glass is a durable and versatile material made primarily from natural resources such as sand, soda ash, and limestone. Its transparency, strength, and chemical stability make it suitable for a wide range of applications, including packaging, construction, and household products. Because it can be reused without loss of quality, glass recycling plays a key role in sustainable manufacturing systems.

Glass recycling significantly reduces the environmental impact of production. Melting recycled material requires considerably less energy than producing new material from raw ingredients. This lower energy demand helps reduce greenhouse gas emissions and decreases overall production costs. In addition, glass recycling conserves valuable natural resources by reducing the need for sand, soda ash, and limestone extraction.

During the recycling process, collected material is sorted, cleaned, and crushed into cullet. This cullet is then used as an input in manufacturing furnaces, where it improves melting efficiency and extends equipment life by lowering operating temperatures. New bottles and jars produced from recycled content offer the same quality, safety, and performance as those made from virgin materials.

By increasing collection rates and investing in efficient processing systems, glass recycling supports circular economy principles. It reduces landfill waste, conserves raw materials, and contributes to more energy-efficient and environmentally responsible industrial production.

Yes, glass is recyclable. Glass is made from natural materials such as sand, soda ash, limestone, and other minerals. Glass can be recycled indefinitely without any loss in quality or purity and it is a raw material that can be used to make new glass containers.

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

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.

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:

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.
Retail locations: Some retailers, such as grocery stores, may have glass recycling bins where customers can drop off their glass bottles and jars.
Schools and offices: Many schools and offices have recycling programs in place, where you can drop off glass to be recycled.
