Laminated Glass Recycling Advances

Approximately 11 million tons of architectural glass are disposed in landfills each year. Infinite Recycled Technologies in Albert Lea, Minn., a division of Watson Recycling, is working to change that. The company has developed technology that recycles laminated glass by separating the glass lites from the plastic interlayer through a mechanical process.

“When it comes to laminated glass we are able to recycle just about 100%. The plastic and glass are fully recyclable with some small loss,” says Jeremiah Watson, CEO of the company.

Several glass manufacturing customers approached Watson Recycling looking for a way to recycle laminated glass. Watson says at first his family-owned company wasn’t interested, so reached out to others that could possibly take on the jobs. Once the company realized that nobody was recycling it, they decided to do it themselves.

“We invested the time and resources into it. We’ve been working on this for a couple of years now,” says Watson.

Infinite Recycled Technologies has been accepting laminated glass for around nine months on a limited basis.

“We have worked with customers to try to divert as much as we can from the landfills,” says Watson, adding that most of the laminated glass is architectural. “Cardinal Glass was one of the first companies to jump on board.”

Infinite’s current capacity to recycle laminated glass is limited, but the company is planning to ramp up its capacity soon.

“We’ve moved to a new facility and are installing the equipment now,” says Watson. “We’ll be able to recycle about 20,000- 30,000 tons per year once we’re done with the build-out.”

The company is intent on running its recycling production line and making sure all the kinks are worked out before pushing ahead with anything beyond its current capacity.

Watson sees the demand for laminated glass recycling increasing as glass manufacturers realize the cost savings and sustainable benefits.

“Many companies know how long it takes glass to break down. On average, it takes 1 million years for a glass bottle to break into sand,” says Watson. “They understand that they are filling landfills with something that will never go away … Landfill space is also limited.”
