Georgia Tech’s Global Student Experience (GSE) Implementation Team has funded 13 faculty proposals as part of an initial round of support to fund start-up costs for projects and programs tied to global experiences in undergraduate or graduate curricula.
Co-chaired by Adam Stulberg, chair of the Sam Nunn School of International Affairs, and Amy Bass Henry, executive director of International Education, the GSE was created after the launch of the Institute’s strategic plan and is an implementation initiative around the Connect Globally focus area. Released in August 2022, the GSE’s request for proposals focused on funding for academic and research faculty to develop new academic offerings on campus and abroad, find synergies between faculty research and other goals of the institution, and support Georgia Tech students in their growth, development, and well-being.
Five of the six Colleges are represented in the first round of funding. All projects are global, transnational, cross-cultural, interdisciplinary, or tie to a Georgia Tech international campus or initiative, all core values of the GSE. Five of the 13 proposals were co-funded with Sustainability Next and will integrate United Nations’ Sustainable Development Goal (SDG)-related themes into global programs. Proposals that aligned with additional Institute Strategic Plan goals, such as Diversity, Equity, and Inclusion and Transformative Teaching and Learning, were prioritized. The projects include:
- Launch new faculty-led study abroad programs (Turkey, South Africa)
- Design and launch of a new, interdisciplinary capstone (Puerto Rico)
- Adapt and integrate a globally- and sustainability-focused technical elective into a School of Civil and Environmental Engineering study abroad program (United Kingdom)
- Create a sustainability-focused Global@Home program
- Bolster participation in exchange programs, develop new internship opportunities (Germany)
GSE will invite proposals again for FY24. Inquiries can be directed to gse@oie.gatech.edu.
The Office of the Vice Provost for International Initiatives (VPII) also issues an RFP for Denning Seed Funds annually in December (florence.stoia@provost.gatech.edu).

Helping Measure the Impact of Air Pollution on South Metro Atlanta Children
Dec 06, 2022 — Atlanta, GA
![.](/sites/default/files/styles/news_first_image/public/news-images/school%20pollution.jpg?itok=Z7YD5rTS)
Researchers from the Georgia Tech’s School of Economics will look at the impacts of air pollution on students at 11 south metro Atlanta schools as part of a $498,401 grant to a community organization from the U.S. Environmental Protection Agency.
The funding announced this week will enable the Center for Sustainable Communities — led by School of Public Policy alumnus Garry Harris, MSEEM 2022 — to install air quality monitoring stations at south metro schools located in minority and low-income communities near highways. Vehicles are a significant source of air pollution.
Dylan Brewer, an assistant professor in the School of Economics and co-principal investigator on the project, will work with his colleagues, Assistant Professor Daniel Dench, and Chair Laura Taylor to study the impact of pollution at the eleven schools. Researchers will compare pollution and test scores at those schools to a control group located further away from major roadways. One goal is to assess how pollution levels impact student test scores.
Meanwhile, researchers at the Georgia Tech Research Institute (GTRI) will develop an educational outreach program to help the students learn how to monitor air pollution at their schools in real time. Researchers hope that work will empower students to better understand the impact of air quality in their communities.
“Low-income and minority communities are often located near major sources of pollution. There’s growing evidence that these pollutants affect cognition and learning, potentially leading to worse educational outcomes. The more we know about these effects, the more we can do to mitigate the problems here in Atlanta and around the world,” said Brewer.
Kevin Caravati — the manager of the Energy and Sustainability Research Program at GTRI, Research Scientist Matthew Swarts, and Research Engineer Soniya Bhagat are the members of the GTRI educational outreach team.
Michael Chang, an atmospheric scientist in the Brook Byers Institute for Sustainable Systems, will advise the team on pollution monitoring, quality assurance, and data analysis.
Brewer said the team hopes to have research findings to share by 2025.
The award is part of EPA’s American Rescue Plan-funded program to address health disparities arising from pollution and the Covid-19 pandemic. The EPA awarded $53.4 million to 132 air monitoring projects in 37 states. The Center for Sustainable Communities project is the only one selected in Georgia.
The School of Economics and the School of Public Policy are units of the Ivan Allen College of Liberal Arts.

Do Electric Scooters Reduce Car Use?
Nov 03, 2022 — Atlanta, GA
![Two women on scooters](/sites/default/files/styles/news_first_image/public/news-images/MicrosoftTeams-image%20%2827%29.jpeg?itok=nAcP1myQ)
Banning scooters may reduce sidewalk congestion and keep would-be riders and pedestrians safer, but it comes at a cost, according to new research from Georgia Tech’s School of Public Policy.
In a study examining the impact of Atlanta's 2019 ban on e-scooters and e-bikes in the city, researchers found that average commute times increased by about 10%. Travel to stadium events such as soccer games increased by almost 12 minutes per trip or 37% increase in travel times while the ban was in effect.
For Atlantans, that adds up to 784,000 extra hours sitting in traffic each year — and that’s just between 9 p.m. and 4 a.m. when the ban was in effect. A moratorium during peak rush hour would cause even more congestion, the study’s principal investigator, Omar Asensio confirmed. Expanding the scope of their study, Asensio and his team in Georgia Tech’s Data Science and Policy Lab estimate that e-scooters, e-bikes, and other micro-mobility options can save an average of 17.4% in travel time for drivers nationally.
“These are fairly significant congestion effects that most travelers will feel and as an unintended consequence of the safety regulation,” said Asensio.
New data settle an old debate
The study, conducted in Georgia Tech’s Data Science and Policy Lab and published in Nature Energy, is the first to definitively show that investing in micro-mobility infrastructure such as e-bikes, e-scooters, and bike lanes can reduce traffic congestion and carbon emissions in cities. The research accounted for the rise in popularity of ride-sharing services and other sources of traffic.
Previous studies on micromobility were controversial and contradictory because they relied on travel surveys, which can be unreliable and are subject to biases resulting from self-reported data, Asensio said. This motivated his search for a more rigorous, data-driven approach to answering the question.
The opportunity arose when Atlanta banned scooters with a geo-fencing policy in 2019. The ban was done with a remote shutdown on all scooters within a certain perimeter, which ensured compliance across the city. Previous moratoriums in other places relied on people to choose to cooperate and follow the rules, so this 100% compliance rate was unique to Atlanta.
“I thought, okay, that's interesting because now we have near-perfect behavioral compliance in response to a policy intervention, which turns out to be extremely rare,” Asensio said. “All of a sudden, if you're without the use of the scooter, what do you do? This created a great natural experiment, to be able to precisely measure the traffic times before and after this policy intervention and in doing so, test behavioral theories of mode substitution.”
In addition, Asensio and his team received early access to the then-new Uber Movement Dataset, which gave them detailed information about commute times across the city that previously had to be collected by surveys as well. In short, the stars aligned in 2019 for the debate over the true impact of micro-mobility on city traffic to finally be settled.
Mary Feeney, program director for the Science of Science Program at the National Science Foundation, which supported the research, said “Asensio and his team are using newly available ‘big data’ sources to tackle practical questions with real policy implications. Bringing the appropriate data and analytical approaches to these problems helps empower decision-makers to enact evidence-based policy.”
Public safety vs. congestion and emissions
The regulation in Atlanta was one of many that U.S. cities put in place in response to increased accidents and hospitalizations from micro-mobility devices.
Reducing congestion also reduces emissions, noted Camila Apablaza, who worked on Asensio’s team along with Savannah Horner, Cade Lawson, and Edward Chen. “I thought this was an important question because the impact of certain modes of transportation, such as scooters, is sometimes overlooked,” she said. “We know that electric mobility will be the main contributor to decarbonizing the passenger transportation sector, therefore we need to understand the interactions between different modes of electric transportation.”
But, “the point of this paper is to present the idea that it’s not just as simple as ‘we should ban the scooters,’ right?” said Chen. “We have found that there are, in fact, trade-offs between banning them for public safety versus allowing them to relieve traffic congestion, and whether or not city governments make the decision does ultimately have an impact on people's daily lives.”
Economic impact
The researchers found that e-scooters and e-bikes do, in fact, reduce congestion on the road by substituting some personal vehicle or ridesharing use rather than only public transit or walking. When the estimated saved time for drivers nationwide is translated into monetary value, Asensio approximates that it adds up to $536 million a year.
“This is also just a personal thing,” Chen added. “I’ve lived around here my whole life. I start seeing these scooters around, and this kind of answers that fundamental question: are people actually using these, and are these actually replacing trips and inherently reducing all these carbon emissions?”
What’s Next?
The Data Science and Policy Lab partners with the private sector and city governments on data innovations in policy analysis and impact evaluation. Follow-up research to this project could dig deeper into the specific transit substitutions people choose and why, Asensio said.
“I think modeling the emissions impacts for those will continue to be an ongoing kind of investigation,” he said. “When it comes to electrification, micro-mobility is just one of many strategies that are aggressively being invested in by both the public and the private sector. It's a really exciting opportunity to meaningfully reduce emissions and to benefit from the public health co-benefit of reduced air pollution.”
The paper, “Impacts of Micromobility on Car Displacement With Evidence From a Natural Experiment and Geofencing Policy” was funded by Asensio’s 2020 NSF Faculty Early Career Development Program (CAREER) (Award No. 1945532). It is available at https://doi.org/10.1038/s41560-022-01135-1.

Bio-Inspired Maker Space Opens in Kendeda Building
Oct 17, 2022 — Atlanta, GA
![EcoMake logo paired with image of the signage in the entrance to the new maker space.](/sites/default/files/styles/news_first_image/public/news-images/EcoMake_Bio-inspired_Maker_Space_Picture_combined.jpg?itok=b21lpA_l)
At first glance, the new maker space opening in the Kendeda Living Building for Innovative Sustainable Design might look like many others. However, the space, named EcoMake, has some important differences. Because it is housed in the Kendeda Building, there are strict standards for what types of materials and equipment can be used there in order to maintain its Living Building Certification. For example, you will find several 3-D printers there, like almost all maker spaces, but the plastic filament used in them is made from recycled plastic, perhaps recycled on-site with equipment in the lab itself.
Some might regard such restrictions as too limiting to their creativity or design goals. Viewed another way, this approach opens up a unique set of possibilities. Biologically Inspired and Green Design (BIG-D) is a field of study (sometimes referred to by different names, like “biomimicry”) that has demonstrated a lot of promise in the past few decades. This approach aims to translate the billions of years of knowledge and design wisdom embodied in our biological world into innovative green products. However, no matter how green the design of a product, they are often manufactured with traditional processes with limited consideration for energy, toxicity, water, or material use. Having a lab like EcoMake will help to usher in the field of study of Biologically Inspired and Green Manufacturing (BIG-M). BIG-M will require knowledge, equipment, and resources that are much different than traditional fabrication methods. Like natural systems, this new facility will operate within the means of nature, using no more energy or water than can be generated from its geometric footprint, and producing no more waste than it can assimilate on site.
EcoMake has the following tools and equipment (so far):
- 8 - Prusa I3S+ 3-D Printers
- 5 - Ender 3 Pro 3-D Printers
- EinScan-SP 3-D Object Scanner
- Mark-10 ESM303 Mechanical Tester
- 300-X Digital Microscope
- 3Devo Filament Extruder
- Shini SG-16N Plastic Granulator
- Plastic Chip Dryer
- Singer Heavy Duty 4423 Sewing Machine
- Complement of Standard Fabric Crafting Equipment
EcoMake, the bio-inspired maker space will be open to students from all disciplines. It is supported by the Colleges of Design, Engineering, and Biology, and the Brook Byers Institute for Sustainable Systems. Contact Michael Gamble for more information.

Joel Kostka Awarded $3.2 Million to Keep Digging into How Soils and Plants Capture Carbon — And Keep It Out of Earth’s Atmosphere
Sep 29, 2022 — Atlanta, GA
![_](/sites/default/files/styles/news_first_image/public/news-images/SPRUCE%20enclosure.jpeg?itok=vYEbyj2u)
Joel Kostka will soon receive $3.2 million from the Department of Energy (DOE) to build upon research that has ranged from northern Minnesota peat bogs to coastal Georgia wetlands, all to learn how climate change impacts soils and plants that trap greenhouse gasses — and whether some of those plants could end up as eco-friendly biofuels.
Kostka, a professor and associate chair of research in the School of Biological Sciences with a joint appointment in the School of Earth and Atmospheric Sciences, will receive funding as part of a wider $178 million dollar DOE effort to advance sustainable technology breakthroughs that can improve public health, help address climate change, improve food and agricultural production, and create more resilient supply chains. The 37 new projects also include efforts to engineer plants and microbes into bioenergy and improve carbon storage.
Kostka’s wetlands research will continue in the salt marshes off Georgia’s coast, where his team has already conducted studies on the microbial life that benefits Spartina cordgrass in those areas, helping to strengthen resilience of the plant to sea level rise and catastrophic storms.
The DOE’s funding initiative is split into four groups. Kostka’s studies will focus on the role of microbiomes — all the microorganisms living in a particular environment — in the biogeochemical cycling of carbon in terrestrial soils and wetlands by using genomics-based and systems biology.
Other research areas involve renewable bioenergy and biomaterials production; quantum-enabled bioimaging and sensing for bioenergy, and research to characterize gene function in bioenergy crop plants.
“Our project seeks to understand the controls of soil organic matter degradation and the release of greenhouse gasses, both of which are largely mediated by microbes” Kostka said. “And then also, as we've been studying for many years now, how climate drivers — principally the warming of ecosystems and carbon dioxide enrichment in the atmosphere — limit greenhouse gas release to the atmosphere. How might changes in plant and microbial communities lead to climate feedbacks, thereby accelerating the release of greenhouse gasses from soil carbon stores?”
That question has driven much of Kostka’s research team in the past as they focused on how soil microbes break down biomasses like woody plants and peat mosses, at an Oak Ridge National Laboratory facility in northern Minnesota called Spruce and Peatland Responses Under Changing Environments (SPRUCE). Kostka’s team is using genomics to study all the genes that code for microbial enzymes that decompose biomass in soil and how plants, which are also changing with climate, impact microbiomes by providing carbon sources that fuel microbial activities. In particular, the work is focused on lignocellulose or lignin, which gives plants their rigidity or structure and arguably comprises the most abundant renewable carbon source on the planet.
“We're just at the point now where we finally have the tools to unlock the black box of soil microbiology and chemistry,” Kostka said. “Recent advances in sophisticated analytical chemistry methods used to quantify microbial metabolites along with improved metagenome sequencing approaches enable us to better uncover metabolic pathways.”
Kostka will serve as principal investigator of the research team for the grant. That team includes School of Biological Sciences researchers Caitlin Petro, research scientist, and Katherine Duchesneau, a third-year Ph.D. student; co-principal investigator Kostas Konstantinidis, Richard C. Tucker Professor in the School of Civil and Environmental Engineering; Rachel Wilson, postdoctoral scholar, Florida State University; Malak Tfaily, associate professor, University of Arizona; and Chris Schadt, senior staff scientist, Oak Ridge National Laboratory.
Unlocking the “enzyme latch” hypothesis
As part of his new research, Kostka will revisit what scientists call the “enzyme latch” hypothesis. This could help uncover the mechanisms by which soils and plants capture harmful greenhouse gasses, and what prompts their release into the atmosphere.
The idea behind this hypothesis is that when soils are wet, they lack oxygen, which suppresses a specific class of enzymes, oxidases, that catalyze the beginning steps in the microbial breakdown of organic compounds produced by plants in soil. When oxidases are suppressed, the breakdown products of lignin, phenolic compounds, accumulate and poison the rest of the microbial carbon cycle. Thus a single class of enzymes may be responsible for keeping greenhouse gasses like carbon dioxide and methane captured within the soil.
“The climate linkage here is that it's thought that as the climate warms, we'll get more greenhouse gas production, because simply it'll be warmer, and microbial enzymes work faster at higher temperature. But then also, in wetlands in particular, the hypothesis is that as wetlands warm, they're going to dry out. And so when a wetland dries out, you're going to get more injection of oxygen-rich air into the soil, which would then accelerate the breakdown of organic matter.”
When that happens, it could also mean different plants having an impact on carbon storage and the breakdown of biomass. “As wetlands dry out, plant communities in northern peatlands where most of Earth’s soil carbon is stored, are expected to shift from a dominance of mosses, which do better when it's wet — to woody plants, shrubs, and trees that do better with less water, when it's drier. That would in turn potentially spark the release of more reactive carbon compounds from plant roots — mosses don’t have roots — which would likely accelerate organic matter decomposition and the production of more greenhouse gas in a feedback loop with climate.”
Kostka’s research may also help to develop new approaches for converting woody biomass into potential alternative energy sources. “To make our society more sustainable, we have to basically recycle everything, or reuse as much as we can. And that includes the biomass from plants that can be grown on more arid lands that are less suitable for food crops,” he said, referring to plant-based materials that can be used to produce biofuels and bioenergy. “And so the DOE is leading research efforts to understand the controls of biomass degradation in plants such as switchgrass and poplar.”
Kostka and Konstantinidis will develop a database of genes that code for the breakdown of lignocellulose and lignin, compounds that largely make up plant biomass and for which metabolic pathways of degradation have been elusive. Kostka and his colleagues will also have access to the extensive resources of the DOE Genomic Sciences program, including a collaboration with the agency’s Joint Genome Institute.
“We hope that information generated from our project can be used to improve methods for breaking down woody biomass so that it can be used in a sustainable way to produce biofuels,” Kostka said.

![Side by side portraits of John Crittenden and Beril Toktay.](/sites/default/files/styles/news_first_image/public/news-images/Crittenden_and_Toktay_w_captions.jpg?itok=OeLx7BxX)
Side by side portraits of John Crittenden and Beril Toktay.
John Crittenden will be stepping down as executive director of BBISS effective August 31, 2022. Beril Toktay, Professor of Operations Management, Brady Family Chairholder, and Regents’ Professor, will serve as BBISS’ interim executive director. Beril said, “John took the inclusion of the word ‘Systems’ in BBISS’ name to heart at a time when large interdisciplinary research collaborations at Georgia Tech were still a rarity. The bold vision now coming out of Georgia Tech’s Strategic Plan 2020-2030 and the Sustainability Next strategic plan initiative can be directly linked to John’s leadership and his challenge to ‘go bigger.’ I am delighted to accept the baton and run the next leg in advancing BBISS’ mission in collaboration with the Georgia Tech sustainability community.”
John will continue as a faculty member, educator, mentor, and researcher at Georgia Tech in the School of Civil and Environmental Engineering, maintaining his appointment as GRA Eminent Scholar in Sustainable Technologies. John has led BBISS since 2009, when the prior Institute for Sustainable Technology and Development (ISTD) was renamed in honor of Brook Byers (a Georgia Tech alumnus, sustainability advocate, and founding president of the Kleiner Perkins venture capital firm).
As a world-renowned researcher, John has made, and continues to make, critical contributions in the fields of water treatment (having co-authored the preeminent book on the subject which is used by 300 universities around the world), pollution prevention, energy harvesting technologies, the food-energy-water nexus, sustainable materials, sustainable urban infrastructure, sustainable engineering pedagogy, advanced modeling of urban systems, and urban form and policy.
Among John’s many awards and honors are: Member of the National Academy of Engineering; Fellow of the American Society of Civil Engineers; Member of the European Union Academy of Sciences; Member of the Chinese Academy of Engineering; American Institute of Chemical Engineers 100 Eminent Chemical Engineers in Modern Times; Athalie Richardson Irvine Clarke Prize from the National Water Research Institute; Simon W. Freese Environmental Engineering Award from the American Society of Civil Engineers; and the Chinese Friendship Award. The American Chemical Society will host a special symposium series to honor John’s long-term accomplishments in sustainability and physical chemical treatment processes for engineered water infrastructure systems at the Fall 2022 ACS meeting in Chicago.
As the leader of BBISS, John also fostered a dedicated team of staff, students, and faculty. The many students who have participated in sustainability research inherited his systems perspective and have carried it into their careers. He oversaw the development of several programs to support career development and collaboration, including the BBISS Graduate Fellows, the BBISS Faculty Fellows, and the Brook Byers Professors, all made possible with donations from Brook and Shawn Byers. He has been a tireless sponsor of early- and mid-career researchers, nominating them for awards and memberships on committees, and providing valuable advice. He has hosted visiting scholars from all over the world, engaging them in interdisciplinary research and the development of solutions to global sustainability challenges.
Julia Kubanek, Vice President for Interdisciplinary Research, shared the following comments: “Thank you, John, for the many programs you have initiated and the research that you have supported and inspired while leading BBISS. On behalf of all the faculty, students, and staff at Georgia Tech, I look forward to continuing to engage with you as a faculty member of the School of Civil and Environmental Engineering.”
Beril Toktay has made varied high-impact contributions to sustainability at Georgia Tech since she joined the Institute in 2005. She is the founding faculty director of the Ray C. Anderson Center for Sustainable Business in the Scheller College of Business. Beril served as the co-architect and co-executive faculty director of Serve-Learn-Sustain, Georgia Tech’s campus-wide academic initiative offering students opportunities to collaborate with diverse partners on key sustainability challenges to help create sustainable communities. She was also Scheller College’s ADVANCE Professor, a role dedicated to the advancement of women and underrepresented minorities in academia. Beril is currently serving as co-chair of Sustainability Next, the sustainability and climate-focused strategic planning initiative of Georgia Tech’s Strategic Plan 2020-2030.
Beril is regarded as one of the most influential scholars in the field of sustainable operations management. Her research helped to introduce sustainability into the field of operations management, and she has had a significant hand in shaping its ongoing development, including serving as area editor in Environment, Energy and Sustainability for Operations Research, co-editor of the Business and Climate Change special issue for Management Science, and as department editor in Health, Environment and Society in Manufacturing and Service Operations Management (MSOM). For her pioneering role in advancing sustainable business scholarship and her leadership in building a sustainable operations community, respectively, she was elected Distinguished Fellow of the INFORMS MSOM Society in 2017 and received the MSOM Distinguished Service Award in 2018.
Beril values interdisciplinary research and education. Earlier in her Georgia Tech career, she served as the coordinator of ECLIPS (Georgia Tech Focused Research Program on Expanding Closed-Loops in Production Systems), an interdisciplinary group of faculty from management, engineering, and public policy interested in circular economy solutions. Her NSF-funded research on circular economy enterprise solutions involved collaborators from mechanical engineering and industrial and systems engineering. For her translational work in this area, she received the 2021 Sustainability Champion Award from the Global Electronics Council (formerly known as the Green Electronics Council). In 2017, Beril co-developed the Carbon Reduction Challenge program in collaboration with the Georgia Tech Global Change Program. This program challenges undergraduate student interns to identify a project that achieves significant reductions in carbon emissions and yields cost savings for their host company.
Through her role in the Ray C. Anderson Center for Sustainable Business, Beril has been instrumental in creating the Drawdown Georgia Business Compact, a statewide, business-led, collective action initiative aimed at achieving a just, prosperous, and sustainable transition towards net-zero carbon emissions in the state by 2050. In 2019, the Metro Atlanta Chamber of Commerce selected her as an E3 Impact Award Finalist, an award that recognizes “visionary individuals advancing sustainability in Atlanta.”
“Beril’s sustainability and business expertise as well as her experience leading teams and initiatives will ensure that BBISS remains on a strong footing and can continue to grow its impact,” said Julia Kubanek. “I’m especially excited about new ideas coming out of the Sustainability Next strategic planning effort that can contribute to the evolution of BBISS.”
Beril will lead BBISS until a new executive director is selected through a process that will be announced by the Vice President for Interdisciplinary Research later this year.

Paul Kohl (School of Chemical and Biomolecular Engineering) and Marta Hatzell (George W. Woodruff School of Mechanical Engineering) will lead CASFER’s efforts at Georgia Tech.
The Center for Advancing Sustainable and Distributed Fertilizer Production (CASFER) is a collaborative effort between the National Science Foundation (NSF) and five universities.
Thanks to efforts to combat climate change, many have heard the catchphrase “closing the carbon loop” — a global effort to convert carbon dioxide into something useful to mitigate the damaging effects of pollution on the planet. Another environmental challenge relates not to carbon dioxide but nitrogen. Now, an ambitious plan to close the nitrogen loop is underway, and with it comes the potential to revolutionize agriculture in the U.S. and around the world.
The Georgia Institute of Technology will be part of CASFER, an NSF Engineering Research Center (NSF-ERC), with four other universities. Supported by an initial grant of $26 million from NSF, CASFER seeks to transform the U.S. from nitrogen cycle pollution to a nitrogen circular economy by developing new technologies and programs for capturing, recycling, and producing decarbonized nitrogen-based fertilizers (NBFs). Georgia Tech is joined by Florida Agricultural and Mechanical University, Case Western Reserve University, the Massachusetts Institute of Technology, and Texas Tech University, which will lead the effort and serve as CASFER’s headquarters.
Nitrogen is used in many commercial applications, but one of the most significant uses is in NBFs for growing food. NBFs are put out into fields, but most do not get used — 80% are washed away and wasted, ending up as pollutants in the watershed. With support from NSF, this team of universities will attempt to recover and reuse nitrogen compounds, the principal element in fertilizers.
“By taking pollutants out of the water and converting them for use, we are taking a negative and making a positive out of it,” said Paul Kohl, Regents' Professor and Thomas L. Gossage Chair in the School of Chemical and Biomolecular Engineering (ChBE) and co-lead of the CASFER effort at Georgia Tech, along with Marta Hatzell, associate professor in the George W. Woodruff School of Mechanical Engineering. “This process will both decrease pollution and lower the cost of farming.”
CASFER has three areas of focus it will pursue to achieve its goal. The first involves measuring and analyzing data to identify new opportunities and locations for collecting wasted fertilizer and determining how exactly the fertilizer affects individual environments.
The second area — Kohl and Hatzell’s focus — is the actual collection and separation of nitrogen compounds from the three types of environments where they usually show up: produce farms, livestock farms, and wastewater treatment plants. They will develop specialized separation methods to pull nitrogen pollutants out of the various environments, creating new types of polymer membranes that work to separate and concentrate the compounds into solutions that can be converted for future use. The work will start in the laboratories at Georgia Tech, but later the team will build test beds — portable laboratories the size of small trailers — to test their separation methods on-site.
“All our separations technologies will be modular, electrified, and largely decarbonized,” said Hatzell. “Our overall goal is to design processes that synthesize new or recover used fertilizers from waste at the same or lower price than traditional chemical manufacturing processes.”
The third area is reconverting the concentrated solutions into usable fertilizer. Humans have been making fertilizer the same way for more than 100 years, using an expensive chemical process that requires natural gas — a resource in short supply. CASFER researchers will develop the conversion methods to create new fertilizers and strategies for dispensing it back into fields for growing crops.
“One strength of NSF Engineering Research Centers is their ability to bring interdisciplinary academic teams together in convergent research to identify novel approaches to thorny societal challenges,” said NSF Assistant Director for Engineering Susan Margulies. “With their unique testbeds and industry partners, the centers innovate and translate solutions that are effective and sustainable.”
CASFER is poised to bring about dramatic changes to the agriculture industry. Since the inception of the Engineering Research Centers program in 1985, the NSF has awarded fewer than 100 grants to open ERCs, which are designed to foster innovation and collaboration between industry leaders, government agencies, and institutions of higher education.
“For decades, NSF Engineering Research Centers have transformed technologies and fostered innovations in the United States through bold research, collaborative partnerships, and a deep commitment to inclusion and broadening participation,” said NSF Director Sethuraman Panchanathan. “The new NSF centers will continue the legacy of impacts that improve lives across the nation.”
Looking to the future, universities will launch workforce development efforts like training and education to prepare a new generation of farmers and scientists for work in the nitrogen circular economy.
Georgia Tech researchers involved in the grant include Kohl (Co-Thrust Leader), Andrew Medford, and Joseph Scott from ChBE; Peter Hesketh (Co-Thrust Leader) and Hatzell (Thrust Leader/Co-PI) from the Woodruff School; Mary-Lynn Realff from the School of Materials Science and Engineering; Lizanne DeStefano (EWD Lead) from CEISMC; and Jie Xu and Milad Navaei from the Georgia Tech Research Institute.

For decades, engineers and scientists have looked to nature for inspiration. One of the most famous examples is Swiss electrical engineer George de Mestral. In 1955, he invented the hook and loop fastener (which he later named Velcro) after studying burdock burrs that kept sticking to his clothes during a hunting trip. For the birth of flight, the Wright brothers studied how birds change the angle of their wings to roll right or left while in the air. They would use the example to refine their control systems in the world’s first successful motor-operated airplane.
A number of Georgia Tech researchers are also focused on biologically inspired design, ranging from the study of how honey bees transport pollen pellets to how small, snakelike lizards move.
With the assistance of a $3 million National Science Foundation grant, Georgia Tech’s Center for Education Integrating Science, Mathematics, and Computing (CEISMC) and the Center for Biologically Inspired Design (CBID) are partnering on a three year research project that introduces biologically inspired design to high school students throughout metro Atlanta.
