The Department of Technology and Society (T&S), one of eight departments in the College of Engineering and Applied Sciences at Stony Brook University, applies concepts and tools drawn from natural sciences, engineering, and social sciences to examine and enhance the relationship between technology and our society, both regionally and globally. These concepts include systems theory, methods and tools for decision making, and science-technology-society (STS) frameworks. In step with the SUNY 2020 initiative to scale the intellectual capacity of the academic community, T&S is deepening its points of focus to center on energy-environmental systems, and engineering & technology workforce policy.

Report: Single Stream Recycling Leads to 25 Percent Increase in Recyclables Recovered - April 21st, 2015

Researchers at the Department of Technology and Society at Stony Brook University released a report today that analyzed the 2014 Town of Brookhaven switch from dual stream recycling (separating the collection of paper and containers) to single stream recycling (paper and containers collected together). The report revealed that the change led to a 25 percent increase in recyclables recovered from 2013 to 2014, and significantly fewer recyclable materials mixed in with the disposable trash.

The report, titled "Analysis of the Change from Dual Stream to Single Stream Recycling for the Town of Brookhaven (Long island, NY)", led by Dr. David J. Tonjes, Assistant Professor in the Department of Technology and Society, and a researcher for the Waste Reduction and Management Institute at the School of Marine and Atmospheric Sciences (SoMAS), compares and analyzes recyclable materials and trash disposals within the town over a two-year period.

"The results of the report surprised me," said Dr. Tonjes. "We did not expect to detect such a large shift in the waste stream over two years, and we did not predict that single stream recycling would lead to increases in recycling efficiency like this."

The research team, which includes Dr. Tonjes, Omkar Aphale, Lori Clark, and Krista L. Thyberg, is likely to continue to sample the Town's waste in the future, to determine if the trends continue, and also to track the results of single stream recycling.

The report is available here.

The Existential Threat of Nuclear Weapons - April 24th at 9am in Harriman Hall

The Department of Technology and Society is proud to announce the next talk in the Technology and Policy Speaker Series.

We hope you will join us for this important talk from one of the leading authorities on the state of nuclear weapons.

Please RSVP as soon as possible as seating will be limited.

Date:  April 24th
Time:  9:00am
Location:  Harriman Hall - Room 132 - The Seminar Room on the 1st Floor

Topic:  The Growing Existential Threat of Nuclear Weapons
By:  Dr. Edward Friedman - Professor Emeritus of Technology Management, Stevens Institute of Technology


The Cold War stimulated the development of a world in which two super-powers confronted each other with tens of thousands of nuclear weapons primed for immediate use. While the international situation has changed, a conceptual framework has yet to emerge that encompasses the current multi-centered reality of nuclear existence. Today, rogue states and non-state entities may be undaunted by the doctrine of mutually assured destruction, that amazingly kept us secure for more than sixty years. Pakistan will soon surpass Britain and France as a nuclear power, but the world's attention is focused on Iran. These issues will be discussed along with the very real potential for nuclear terrorism. The topic In today’s complex technological society, policy makers are charged with some of the most critical challenges ever faced by our global society.
