Ferrovial, a global infrastructure operator, and the Georgia Institute of Technology today announced a long-term partnership focused on advancing innovation in transport infrastructure. The partnership will allow for joint research activities, providing new educational and development opportunities for students and enabling Ferrovial to create a more sustainable future for mobility. The agreement was formally signed at the university’s campus in Atlanta.

"Georgia Tech is globally recognized for its expertise in infrastructure and mobility, research, and development,” said Andres Sacristan, CEO of Cintra Global. “Ferrovial understands our industry must remain agile as transportation continues to evolve. By partnering with universities like Georgia Tech, we can continue to improve the traveler experience and better serve our clients by providing new mobility solutions."  

Ferrovial has collaborated with Georgia Tech in research, leveraging its talent for several years. In addition to its expertise in traffic engineering, the Institute has extensive research capabilities in construction, airports, and energy, allowing for a comprehensive and diversified partnership as Ferrovial operates in all these areas.

“Ferrovial is reimagining transportation, and this collaboration will enable Georgia Tech researchers and students to gain a firsthand understanding of the needs of our nation’s infrastructure,” said Ángel Cabrera, president of Georgia Tech. “We are proud to partner with Ferrovial to drive the future of transportation and mobility, which will bring valuable technological innovation and knowledge transfer to our state.”

Ferrovial, through its highways business Cintra, operates five major managed lane projects across the U.S., providing traffic congestion relief to some of the nation’s fastest growing regions. Ferrovial's construction division currently manages several large highway construction projects, including the Transform 285/400 highway improvement project in Atlanta. Subsidiaries Ferrovial Construction and Webber have carried out infrastructure improvements in the state of Georgia that amount to nearly $800 million. Ferrovial Airports is a leading airport investor and operator with key investments in the U.S. Through its vertiports business, the company aims to design, build, and operate the infrastructure required by eVTOL (electric Vertical Take-Off and Landing) aircraft. 

“Aligning with Georgia Tech reinforces Ferrovial’s commitment to sustainably advancing mobility, enhancing safety, and connecting communities in the United States and beyond,” said Sacristan.

On the one-year anniversary of the launch of Sustainability Next, a publicly available version of the plan is being released and several plan initiatives are coming to life.  

Following the creation of Georgia Tech’s 2020 – 2030 strategic plan, the Institute’s executive leadership team launched a task force to create a strategic sustainability roadmap — the Sustainability Next Plan — to help advance some of its most important goals.  

“Sustainability Next is central to Georgia Tech’s commitment to developing leaders who advance technology and improve the human condition,” said President Ángel Cabrera. “As one of the largest technological universities in the world, we have the opportunity and responsibility to help find solutions to the biggest problems we face, achieve the United Nations Sustainable Development Goals, and support a human population that will soon rise to 10 billion while reducing the stress we’re causing on our planet.” 

The plan calls on Georgia Tech to:  

• Be a global sustainability thought leader.  

• Catalyze innovation through education and research.  

• Lead by example in the practice and culture of sustainability. 

 

Since the fall of 2022, Sustainability Next has begun to implement projects, including: 

• The Climate Action Plan to develop a roadmap for integrating climate action strategies across operations, research, and education focusing on climate justice and reducing emissions. 

• Sustainable X, which supports students interested in and passionate about developing climate tech, sustainability, and social impact startups.      

• Sustainability Education Innovation Grants for faculty to expand Sustainable Development Goals concept and skill integration across the undergraduate curriculum.   

• Research Seed Grants to support interdisciplinary climate and sustainability research initiatives.   

• Living Campus connecting Georgia Tech’s built environment and surrounding landscape to serve as opportunities for collaborations between academics, research, industry, operations, and community partnerships. 

These initiatives alone have created collaborations between several sustainability-focused departments on campus, including the Office of Sustainability, the Brook Byers Institute for Sustainable Systems, the Ray C. Anderson Center for Sustainable Business, and the Center for Teaching and Learning.  

 

Creating the Foundation for Successful Implementation 

As an outcome of the strategic plan to more intentionally integrate sustainability and lead by example with campus operations, Georgia Tech restructured its facilities management into Infrastructure and Sustainability (I&S) in 2021. The following year, the Office of Campus Sustainability was restructured into the Office of Sustainability within I&S to bridge sustainability efforts across research, education, and operations. It was later expanded to integrate the departments of utilities, sustainable building operations, and The Kendeda Building for Innovative Sustainable Design. 

Additionally, Sustainability Next has supported the Brook Byers Institute in becoming a transformative unit focused on climate and sustainability that integrates research and education. It has also strengthened ties in the sustainability cluster of the Vice President for Institutional Research, comprising the Byers Institute, the Renewable Bioproducts Institute, and the Strategic Energy Institute — including the permanent integration of Serve-Learn-Sustain into the newly established Center for Sustainable Communities Research and Education. 

 

Looking Ahead 

In the next few months, the Sustainability Next Plan will be supported by a refreshed website, a schedule of sustainability-related events, and calls to action, reinvigorating the sustainability charge set forth in the Institute’s strategic plan. 

The Sustainability Next co-chairs invite every member and unit of the Georgia Tech community to join in bringing the Sustainability Next Plan to life and expanding its ambitions over time so that we can build a just, equitable, and sustainable future — together.

In front of a standing-room-only crowd inside the John Lewis Student Center's Atlantic Theater, global leaders from the Hyundai Motor Group and Georgia Tech signed a memorandum of understanding, creating a transformative partnership focused on sustainable mobility, the hydrogen economy, and workforce development.  

As the automaker continues to construct its Metaplant America site in Bryan County — the cornerstone of Hyundai's $12 billion investment into electric vehicles and battery production across the state of Georgia — today's signing ceremony symbolizes the vision that Hyundai and Georgia Tech share on the road to advancing technology and improving the human condition. 

"As a leading public technological research university, we believe we have the opportunity and the responsibility to serve society, and that technology and the science and policy that support it must change our world for the better. These are responsibilities and challenges that we boldly accept. And we know we can't get there alone. On the contrary, we need travel partners, like-minded innovators, and partners with whom we can go farther, and today's partnership with Hyundai is a perfect example of what that means," Georgia Tech President Ángel Cabrera said.  

The state of Georgia and the Institute have positioned themselves as leaders in the electrification of the automotive industry. Hyundai is among the top sellers of electric vehicles in the United States as the company aims to produce up to 500,000 vehicles annually at the $7 billion Savannah plant when production begins in 2025. The plant will create 8,500 jobs, and the company's total investments are projected to inject tens of billions of dollars into the state economy while spurring the creation of up to 40,000 jobs.  

"It's clear, we are in the right place with the right partners," Jay Chang, president and CEO of Hyundai Motor Company, said. "When our executive chairman first decided on [the site of] the metaplant, one of the first things he said was, 'Make sure we collaborate with Georgia Tech.’ Hyundai and Georgia Tech have a lot in common. We have proud histories. We celebrate excellence, and we have very high standards. What we love about Georgia Tech is the vision to be a leading research university that addresses global challenges and develops exceptional leaders from all backgrounds."  

Spearheading new opportunities for students, the partnership will create technical training and leadership development programming for Hyundai employees and initiate engagement activities to stimulate interest in STEM degrees among students. 

José Muñoz, president and global COO of Hyundai Motor Company and president and CEO of Hyundai and Genesis Motor North America, says the company quickly realized the potential impact of the newly forged partnership with Georgia Tech.  

"Proximity to institutions like Georgia Tech was one of the many reasons Hyundai selected Georgia for our new EV manufacturing facility. Imagine zero-emissions, hydrogen-powered vehicles here on campus, advanced air mobility shuttling people to Hartsfield-Jackson Atlanta International Airport, or riding hands-free and stress-free in autonomous vehicles during rush hour on I-75 and I-85. Together, Georgia Tech and Hyundai have the resources to fundamentally improve how people and goods move," he said. 

In pursuit of sustainability, Hyundai has invested heavily in the potential of hydrogen and plans to lean on the Institute's expertise to explore the potential of the alternative fuel source, primarily for commercial vehicles. Hyundai has deployed its hydrogen-powered XCIENT rigs to transport materials in five countries. 

University System of Georgia Chancellor Sonny Perdue was on hand for Tuesday’s ceremony. Reflecting on his visits to the company's global headquarters in South Korea prior to the construction of the West Point, Georgia, Kia plant, he praised the company's values and world-class engineering ability.    

"This is a relationship built on mutual trust and respect. It's a company, a family atmosphere, and a culture that I respect and admire for the way they do business and honor progress, innovation, and creativity. That is why I am so excited about this partnership between the Hyundai Motor Group and the Georgia Institute of Technology because that will only enhance that," Perdue said. 

Owned by Hyundai, Kia recently invested an additional $200 million into its West Point facility to prepare for the production of the all-electric 2024 EV9 SUV. The plant currently manufactures more than 40% of all Kia models sold in the U.S.  

The partnership also includes field-naming recognition at Bobby Dodd Stadium, which is now known as Bobby Dodd Stadium at Hyundai Field, and provides student-athletes and teams with the resources needed to compete at the highest levels, both athletically and academically.

The water coming out of your faucet is safe to drink, but that doesn’t mean it’s completely clean. Chlorine has long been the standard for water treatment, but it often contains trace levels of disinfection byproducts and unknown contaminants. Georgia Institute of Technology researchers developed the minus approach to handle these harmful byproducts.

Instead of relying on traditional chemical addition (known as the plus approach), the minus approach avoids disinfectants, chemical coagulants, and advanced oxidation processes typical to water treatment processes. It uses a unique mix of filtration methods to remove byproducts and pathogens, enabling water treatment centers to use ultraviolet light and much smaller doses of chemical disinfectants to minimize future bacterial growth down the distribution system.

“The minus approach is a groundbreaking philosophical concept in water treatment,” said Yongsheng Chen, the Bonnie W. and Charles W. Moorman IV Professor in the School of Civil and Environmental Engineering. “Its primary objective is to achieve these outcomes while minimizing the reliance on chemical treatments, which can give rise to various issues in the main water treatment stream.”

Chen and his student Elliot Reid, the primary author, presented the minus approach in the paper, “The Minus Approach Can Redefine the Standard of Practice of Drinking Water Treatment,” in The American Chemical Society.

The minus approach physically separates emerging contaminants and disinfection byproducts from the main water treatment process using these already proven processes:

• Bank filtration withdraws water from naturally occurring or constructed banks like rivers or lakes. As the water travels through the layers of soil and gravel, it naturally filters out impurities, suspended particles, and certain microorganisms.
• Biofiltration uses biological processes to treat water by passing it through filter beds made of sand, gravel, or activated carbon that can support the growth of beneficial microorganisms, which in turn can remove contaminants.  
• Adsorption occurs when an adsorbent material like activated carbon is used to trap contaminants.
• Membrane filtration uses a semi-permeable membrane to separate particles and impurities from the main treatment process.

The minus approach is intended to engage the water community in designing safer, more sustainable, and more intelligent systems. Because its technologies are already available and proven, the minus approach can be implemented immediately.

It can also integrate with artificial intelligence (AI) to improve filtration’s effectiveness. AI can aid process optimization, predictive maintenance, faulty detection and diagnosis, energy optimization, and decision-support systems. AI models have also been able to reliably predict the origin of different types of pollution in source water, and models have also successfully detected pipeline damage and microbial contamination, allowing for quick and efficient maintenance.

“This innovative philosophy seeks to revolutionize traditional water treatment practices by providing a more sustainable and environmentally friendly solution,” Chen said. “By reducing the reliance on chemical treatments, the minus approach mitigates the potential risks associated with the use of such chemicals, promoting a safer water supply for both human consumption and environmental protection.”

“A stitch in time saves nine,” goes the old saying. For a company in Georgia, that adage became very real when damage to a key piece of machinery threatened its operation. The group helping with the stitch in time was the Georgia Manufacturing Extension Partnership (GaMEP), a program of Georgia Tech's Enterprise Innovation Institute that — for more than 60 years — has been helping small- to medium-sized manufacturers in Georgia stay competitive and grow, boosting economic development across the state.

Silon US, a Peachtree City manufacturer that designs and produces engineered compounds used to create a wide range of products — from automotive applications to building materials, such as PEX piping and wire and cable, was experiencing problems with their extrusion line during a time of increasing customer demand. Problems with the drive mechanism on that extrusion line, a piece of equipment critical to the company’s ability to produce, threatened to shut them down. With replacement parts several weeks away, was it safe to continue operating? At what throughput rates? How much collateral damage might be incurred if they continued to operate?

That’s when Silon managers turned to GaMEP for help.

After working through ideas with GaMEP’s manufacturing experts, the team installed wireless condition monitoring sensors that provide continuous, real-time insights on their manufacturing assets’ health. With the sensors, Silon was able to find a sweet spot that not only allowed them to continue operating but also kept them from overexerting the equipment, preventing further damage.

The solution to that problem has now become a routine part of Silon’s process, as company technicians continue to use this sensor technology for early detection of any deviations or anomalies in the machinery’s health, allowing the company’s maintenance team to proactively respond by adjusting scheduled maintenance to avoid costly downtime.

GaMEP’s Sean Madhavaraman says, “Silon is more productive than ever and on track for growth. The strong results in this challenge are a great example of the decades-long focus of GaMEP to educate and train managers and employees in best practices, to develop and implement the latest technology, and to work together with businesses to find solutions.”

Daniel Raubenheimer and Matt Gammon, Silon’s general managers, also lauded GaMEP, saying, “GaMEP’s extensive experience within the manufacturing realm has been a great benefit to our company. The wireless condition monitoring sensors allow us to predict future breakdowns and mitigate a potential catastrophe — allowing us to operate in a safe manner, while saving money, time, and effort.”

Workforce diversity in science and technology is widely seen as necessary for continued innovation. For Georgia Tech, striving toward inclusivity starts with a simple but crucial goal: building deep, lasting research partnerships.

Research Next, a planning initiative for Georgia Tech’s research enterprise, was launched by Executive Vice President for Research Chaouki T. Abdallah in 2020 and co-chaired by Tim Lieuwen and Mark Whorton. As part of Phase 3, project teams worked throughout the past year to implement its goals.

One Research Next project team has paved the way for inclusive research collaborations to thrive at Georgia Tech and beyond. The team was charged with identifying opportunities and developing support systems to facilitate research collaborations between Georgia Tech and HBCUs (historically Black colleges and universities) and MSIs (minority-serving institutions).

Since kicking off in March 2022, the project team solidified new research partnerships, developed a digital networking tool to connect Georgia Tech and HBCU researchers, and created and hired a full-time position at Tech for ongoing engagement with HBCUs and MSIs. The group was co-led by George White, senior director for strategic partnerships in the Office of the Vice President for Interdisciplinary Research and principal research engineer at Georgia Tech, and Thomas Martin, chief scientist for the Electro-Optical Systems Laboratory at the Georgia Tech Research Institute (GTRI).

“The goal of our work is not only to support collaborative research with HBCUs and MSIs, but also to strengthen the pipeline of top graduates who will enhance diversity in our state and nation’s workforce,” White said. “One of the first key steps was to hear from the groups we were charged to work with.”

Defining the Challenge

The team began by leveraging GTRI’s longstanding work and connections with HBCUs, which include federally funded collaborative research projects and workforce development initiatives. The group invited representatives from the Tougaloo College Research and Development Foundation (TCRDF), a consortium of HBCUs whose mission is to advance research collaborations between HBCUs and the Department of Defense. Members of TCRDF educated the project team about challenges HBCUs face in obtaining federally sponsored research.

“GTRI has been fortunate to collaborate with TCRDF in support of the U.S. Army’s Combat Capabilities Development Command (CCDC) Aviation & Missile Center’s mission to accelerate research collaborations with HBCUs and MSIs and enrich the workforce with a pipeline of talented graduates,” Martin said.

Throughout the year, the project team hosted seminars with HBCUs where they highlighted research activities at the Institute and discussed how HBCUs could participate in areas of mutual research interests. The team also joined TCRDF’s open virtual meeting hours every week to talk about research engagement opportunities at Georgia Tech.

In addition, they recommended that Georgia Tech create a dedicated, permanent position to facilitate ongoing engagement with HBCUs. Taiesha Smith, the first senior program manager for Georgia Tech’s HBCU/MSI Research Collaboration Initiative, will lead outreach efforts to increase and foster enduring research collaborations.

“I'm excited to be the connective tissue between Georgia Tech, HBCUs, and MSIs in building sustainable and mutually beneficial relationships that lead to successful research collaboration,” Smith said. “I aim to accomplish this goal through a commitment to understanding the needs of HBCUs and MSIs, communicating their value to all stakeholders, and supporting them in making appropriate connections across Georgia Tech and beyond.”

Steps Forward

The project team led the development of a software tool, CollabNext, that facilitates research interaction and collaborations between HBCUs and Georgia Tech. Using the tool, researchers can find partners at HBCUs based on specific disciplines and areas of interest. The tool is currently in beta version and has expanded to include Clark Atlanta University, Morehouse College, Texas Southern University, Fisk University, and the Atlanta University Center (AUC) Data Science Initiative. A website hosts the tool and provides information about the initiative.

The team also is planning a forum that will bring together researchers from Georgia Tech and several HBCUs/MSIs, as well as government officials and industry leaders from top STEM companies. A major goal of the event will be for participants to develop white papers to better position HBCUs and MSIs to compete for large federal funding opportunities. The multi-day event will be organized by the Office of the Vice President for Interdisciplinary Research and is set to take place in November.

Additional steps taken to establish and solidify research partnerships:

• Submitted a joint proposal for an NSF Regional Innovation Engine with TCRDF and seven HBCU/MSI partner institutions.
• Submitted a joint NSF proposal with the AUC Data Science Initiative, Morehouse College, and TCRDF to establish the inaugural research collaboration forum at Georgia Tech.
• Launched the Biomedical Data Science Summer Research Program.
• Prepared a memorandum of understanding (pending) to establish a semiconductor research initiative with HBCU/MSIs.
• Modified an agreement with Ford Motor Company to allow HBCU/MSI institutions to participate in sponsored research projects in collaboration with Georgia Tech.
• Participated in the 2022 National HBCU Week, hosted by the executive director for White House Initiatives on HBCUs. Georgia Tech will participate again in 2023 to introduce CollabNext and present best practices for engaging in collaborative research.
• Submitted proposals to the Department of Energy’s Hydrogen Hub (with Battelle Memorial Institute) and Direct Air Capture Hub (with Southern States Energy Board) to develop a collaborative research and community engagement consortium made up of HBCUs and MSIs.
  • Georgia Tech will serve as an unbiased science convener for the HBCUs/MSIs, which will receive the majority of funding and engagement. This work is in partnership with Tech’s Serve-Learn-Sustain.

“This Research Next project provided the opportunity not only to coordinate efforts across Georgia Tech to enhance research collaborations with HBCUs and MSIs, but also to position Georgia Tech as thought leaders in this initiative,“ said Martin.

Team co-leader George White attended Hampton University, a prominent HBCU, and saw firsthand some of the resource challenges that the institutions face when trying to secure federally sponsored research. The initiative’s mission continues to be important for him personally. 

“Our work with HBCUs supports Georgia Tech’s strategic plan by increasing accessibility and improving the human condition,” he said. “With the vast resources we have here, it is important to work together to find solutions to these pressing challenges.”

What started as a simple errand to deposit a check at a bank drive-through became the kind of “aha” moment found mostly in books and movies.

Georgia Tech researchers had been working on an idea to simplify traditional direct air capture (DAC) systems. Their approach used ambient wind flow to draw air across a new kind of coated carbon fiber to grab CO2. That would eliminate the loud fans used in many systems. And the carbon fiber strands could be quickly heated to release the captured carbon dioxide with minimal heat loss, boosting efficiency.

But they were struggling with how to deploy these new sorbent-coated carbon fibers for maximum effect.

“I had to go deposit a check at the bank, and I went through the drive-through. They had the old pneumatic tubes that come down to transport documents,” said Ryan Lively, Thomas C. DeLoach Professor in Georgia Tech’s School of Chemical and Biomolecular Engineering (ChBE). “There are not many times you have a light bulb moment in your career, but I saw the tubes and I realized, we could put the fibers in something like a bank teller tube canister.

“That’s pretty much what we did, and it worked.”

Centipedes are known for their wiggly walk. With tens to hundreds of legs, they can traverse any terrain without stopping.

“When you see a scurrying centipede, you're basically seeing an animal that inhabits a world that is very different than our world of movement,” said Daniel Goldman, the Dunn Family Professor in the School of Physics. “Our movement is largely dominated by inertia. If I swing my leg, I land on my foot and I move forward. But in the world of centipedes, if they stop wiggling their body parts and limbs, they basically stop moving instantly.”

Intrigued to see if the many limbs could be helpful for locomotion in this world, a team of physicists, engineers, and mathematicians at the Georgia Institute of Technology are using this style of movement to their advantage. They developed a new theory of multilegged locomotion and created many-legged robotic models, discovering the robot with redundant legs could move across uneven surfaces without any additional sensing or control technology as the theory predicted.

These robots can move over complex, bumpy terrain — and there is potential to use them for agriculture, space exploration, and even search and rescue.

The researchers presented their work in the papers, “Multilegged Matter Transport: A Framework for Locomotion on Noisy Landscapes,” in Science in May and “Self-Propulsion via Slipping: Frictional Swimming in Multilegged Locomotors,” in Proceedings of the National Academy of Sciences in March.

A Leg Up

For the Science paper, the researchers were motivated by mathematician Claude Shannon’s communication theory, which demonstrates how to reliably transmit signals over distance, to understand why a multilegged robot was so successful at locomotion. The theory of communication suggests that one way to ensure a message gets from point A to point B on a noisy line isn’t to send it as an analog signal, but to break it into discrete digital units and repeat these units with an appropriate code.

“We were inspired by this theory, and we tried to see if redundancy could be helpful in matter transportation,” said Baxi Chong, a physics postdoctoral researcher. “So, we started this project to see what would happen if we had more legs on the robot: four, six, eight legs, and even 16 legs.”

A team led by Chong, including School of Mathematics postdoctoral fellow Daniel Irvine and Professor Greg Blekherman, developed a theory that proposes that adding leg pairs to the robot increases its ability to move robustly over challenging surfaces — a concept they call spatial redundancy. This redundancy makes the robot’s legs successful on their own without the need for sensors to interpret the environment. If one leg falters, the abundance of legs keeps it moving regardless. In effect, the robot becomes a reliable system to transport itself and even a load from A to B on difficult or “noisy” landscapes. The concept is comparable to how punctuality can be guaranteed on wheeled transport if the track or rail is smooth enough but without having to engineer the environment to create this punctuality.

“With an advanced bipedal robot, many sensors are typically required to control it in real time,” Chong said. “But in applications such as search and rescue, exploring Mars, or even micro robots, there is a need to drive a robot with limited sensing. There are many reasons for such sensor-free initiative. The sensors can be expensive and fragile, or the environments can change so fast that it doesn’t allow enough sensor-controller response time.”

To test this, Juntao He, a Ph.D. student in robotics, conducted a series of experiments where he and Daniel Soto, a master’s graduate in the George W. Woodruff School of Mechanical Engineering, built terrains to mimic an inconsistent natural environment. He then tested the robot by increasing its number of legs by two each time, starting with six and eventually expanding to 16. As the leg count increased, the robot could more agilely move across the terrain, even without sensors, as the theory predicted. Eventually, they tested the robot outdoors on real terrain, where it was able to traverse in a variety of environments.

“It's truly impressive to witness the multilegged robot's proficiency in navigating both lab-based terrains and outdoor environments,” Juntao said. “While bipedal and quadrupedal robots heavily rely on sensors to traverse complex terrain, our multilegged robot utilizes leg redundancy and can accomplish similar tasks with open-loop control.”

Next Steps

The researchers are already applying their discoveries to farming. Goldman has co-founded a company that aspires to use these robots to weed farmland where weedkillers are ineffective.

“They’re kind of like a Roomba but outside for complex ground,” Goldman said. “A Roomba works because it has wheels that function well on flat ground. Until the development of our framework, we couldn’t confidently predict locomotor reliability on bumpy, rocky, debris-ridden terrain. We now have the beginnings of such a scheme, which could be used to ensure that our robots traverse a crop field in a certain amount of time.”

The researchers also want to refine the robot. They know why the centipede robot framework is functional, but now they’re determining the optimal number of legs to achieve motion without sensing in a way that is cost-effective yet still retains the benefits.

“In this paper, we asked, ‘How do you predict the minimum number of legs to achieve such tasks?’” Chong said. “Currently we only prove that the minimum number exists, but we don't know that exact number of legs needed. Further, we need to better understand the tradeoff between energy, speed, power, and robustness in such a complex system.”
