NYSDOT gives Klaw Pantheon glass pozzolan the green light

The New York State Department of Transportation is the first agency to approve the use of Pantheon, a waste glass-derived pozzolan with demonstrated potential for portland cement substitution, in concrete mix designs. Klaw Industries LLC of Binghamton, N.Y. processes the silicon dioxide-rich (> 70 percent) agent to a reactivity level yielding additional calcium silicate hydrate in fresh concrete. Upwards of 75 tons of Pantheon will be used in curb, sidewalk, and barrier mixes on a $21.2 million project along U.S. Route 11 in Whitney Point, N.Y.

Additional Pantheon processing capacity will position Klaw Industries to recycle all
City of Binghamton waste stream glass.

“This project, which enhances safety and walkability while replacing a 77-year-old bridge, is a solid investment in the future of Whitney Point, home to one of the best county fairs in the Empire State,” New York Governor Kathy Hochul noted in an announcement on a partnership tied to the contract. “Coupled with innovations in new technology that will lower carbon emissions, this project will not only shore up the Village’s infrastructure, but make it a more resilient place to live, work and raise a family.”

The Pantheon process emerged from The Cube, a Clarkson University student business incubator program. Early pozzolan demonstrations included concrete flatwork at the school and for the City of Binghamton. “NYSDOT approval is the ‘highest law in the land’ for concrete materials in New York,” says Jack Lamuraglia, a Clarkson electrical engineering graduate who co-founded Klaw Industries in 2019 with mechanical engineer Jacob Kumpton. 

Grants and business plan competition funding equipped them for initial Pantheon production at a Binghamton plant, expansion of which is in the works to meet projected capacity requirements. For now, Lamuraglia concedes, “We can’t make enough of the product to satisfy our customers.”
