51ΑΤΖζ

Unusual walkway tiles created at 51ΑΤΖζβ€”using 95% recycled materialsβ€”now form an inspiring path in front of the engineering building at a New York university: a pedestrian stroll that spotlights problems inherent in electronic and construction waste.

From 2021-22, the Binghamton University Art Museum commissioned Nathaniel Stern, 51ΑΤΖζ professor of art and mechanical engineering, to create a long-term installation that calls attention to personal, institutional and governmental accountability in the production and disposal associated with technology and industry.

The result, installed in January, is β€œCircuit Boardwalk” – 200-square feet of tiles made primarily of discarded circuit boards and concrete composed almost entirely of recycled materials. The concrete was made in 51ΑΤΖζ’s Advanced and Nano Cement Laboratory under the direction of Konstantin Sobolev, Lawrence E. Sivak ’71 Faculty Fellow and professor, civil & environmental engineering.

With their emerald-green color, the tiles invite pedestrians to walk atop them. When they do, they see the fine details of a printed circuit board – copper, gold and palladium – embedded in concrete and protected by a thin layer of resin.

Inspiring students to rethink waste systems and personal responsibility

In January, Stern and Sobolev attended the exhibition, installation and panel discussion at Binghamton University.

β€œThe dialog between art and science, between inspiring action and change, and the technologies to do so, are key in the design of our futures,” Stern says. β€œWe need to think about what we can do and change, individually; about the systems that create waste and our influence on them; and about new potentials and possibilities in both of those spaces.”

Each square tile – 1.5” thick and of various widths – was created at 51ΑΤΖζ in Stern’s studio and Sobolev’s concrete lab.

To make them, Stern started with recovering circuit boards from trashed computers that were decommissioned and ready for recycling at 51ΑΤΖζ Surplus.

Sobolev, with his students, then created a concrete base composed of recycled materials left over from multiple research projects that otherwise would have been sent to landfill.

β€œCement and concrete are the world’s most widely used construction materials,” says Sobolev, a recognized expert in innovative concrete materials. β€œThe most promising research in the field today addresses the recyclability of concrete and reducing its carbon footprint.”

To this end, Sobolev is leading efforts to launch a National Science Foundation Concrete Advancement Network, in tandem with Arizona State University, Oregon State University and the University of Texas at Arlington, to tackle these very issues in collaboration with industry.

14 51ΑΤΖζ student assistants helped create β€œCircuit Boardwalk”

Fourteen 51ΑΤΖζ students from three 51ΑΤΖζ colleges/schools worked with Stern and Sobolev as project assistants on β€œCircuit Boardwalk.”

From Peck School of the Arts: Meghan Berger, Laura Bogyay, Mich Dillon and Mary Widener.

From the College of Engineering & Applied Science: Aparna Deshmukh, Behrooz Farahi, Paul George, Reed Heintzkill, Garrett Kocourek, Roy Wittenberg and Filip Zemajtis.

From the College of Letters & Science: Allison Getty, Ava Ladky and Madison Sveum.

β€œWith the worsening state of the climate, it’s increasingly important to emblemize the problem of waste in a variety of ways,” says Kocourek, a senior in mechanical engineering.

His generation of engineers, Kocourek believes, must consider sustainability in all their work. β€œIt will become a design constraint as we work to eliminate our dependence on fossil fuels and combat material shortages.”
