The University of Georgia New Materials Institute will collaborate on a U.S. Department of Energy-funded research project to explore and optimize strains of bacteria for use in the creation of biologically degrading thermoplastic for polyurethanes and their byproducts. The UGA team, led by Jason Locklin, who directs the Institute, will work with a team from BASF (www.basf.com) to conduct the biological degradation studies for the grant project.

The US DOE awarded $2 million in grant funding to Jon Pokorski and Adam Feist, both researchers from the University of California San Diego, to fine-tune their innovation for thermoplastic polyurethanes and related byproducts. The UGA-BASF team will utilize about a quarter of that funding, over 3 years, to ensure that the material meets the biological degradation requirements specified by the US DOE. The BASF team will be led by Arif Rahman, a thermoplastic polyurethane researcher at the company.

“It’s an honor to be asked by my colleagues at UCSD for help with their project, and it is a tremendous advantage for us to be able to conduct these biological degradability studies with a team from BASF” said Locklin. “Working in tandem with industry means we are all focused on fine-tuning a technology that will be launched into the global marketplace where it can replace current plastics technologies that are accumulating in our landfills and environment.”

BASF and the UGA New Materials Institute have already developed a good working relationship over the last few years, through BASF’s participation as a member company of the Center for Bioplastics and Biocomposites (CB2). CB2 is an Industry-University Cooperative Research Centers program funded by the National Science Foundation, and the UGA New Materials Institute serves as one of four research sites for CB2.

The project “Degradable Biocomposite Thermoplastic Polyurethanes” was funded through the DOE’s BOTTLE program: Bio-Optimized Technologies to Keep Thermoplastics out of Landfills and the Environment; the program isjointly funded by the Office of Energy Efficiency and Renewable Energy’s (EERE) Bioenergy Technologies Office and Advanced Manufacturing Office. The project is part of the DOE’s Plastics Innovation Challenge, which draws on the research capabilities of DOE National Laboratories, universities, and industry to accelerate innovations in energy-efficient plastics recycling technologies.

Creating plastics, particularly packaging, is a complex endeavor. For example, multiple materials may be required to create packaging for a product, based on how far that product has to travel, how long its shelf life might be, and whether it’s packaging for a food item. So, if you are a consumer who is concerned about selecting environmentally-friendly packaging and products, what do you do? Are the claims made on product packaging clear enough to help you make the best decision when it comes time to dispose of that packaging or product? Jason Locklin, director of the UGA New Materials Institute, and Jenna Jambeck, who leads the Institute’s Center for Circular Materials Management, talked to the New York Times about the complicated choices facing today’s consumers.

Locklin, Jambeck help lead effort to shape circular economy research

The University of Georgia New Materials Institute’s Jason Locklin and Jenna Jambeck are collaborating on a virtual workshop series aimed at shaping the future of circular economy research. Locklin, a professor of chemical engineering and founding director of the New Materials Institute, and Jambeck, a professor of environmental engineering and associate director of the Institute, will join experts from academia, industry, government and nonprofits in panel discussions aimed at developing ideas and goals for circular economy research. The workshop series is funded by the National Science Foundation and is led by Melissa Bilec, an associate professor of civil and environmental engineering at the University of Pittsburgh’s Swanson School of Engineering; Bilec is deputy director of the Mascaro Center for Sustainable Innovation (MSCI). Other co-investigators on the grant include Eric Beckman, a professor of chemical engineering and co-director of the MCSI, and, Gregg Beckham, senior research fellow at the National Renewable Energy Lab.

For Evan White, growing up outside Atlanta meant witnessing significant changes in his landscape. His hometown of Lilburn, Georgia, tripled its population between 1980 and 2000, and White watched as nearby woods became neighborhoods and parking lots. He saw trash, much of it plastic, accumulate in the streams and tributaries where he played.

“You don’t have to go very far into nature to see the evidence of human expansion,” said White, now an assistant research scientist at UGA. “Different particles of plastic will wind up at a final resting place according to their chemical reactivity and their density. Most of these plastics like to float on water, and they go where the water goes.”

These formative experiences greatly influenced his career path, leading him to the university’s New Materials Institute, directed by Jason Locklin, and its Center for Advanced Polymers, Fibers & Coatings. White is part of a team focused on a single goal: to develop materials and plastic replacements that completely break down and return to nature when discarded.

UGA-led projects for NSF-funded CB2 ‘on track’ for 2020

Two research projects that are being led by University of Georgia New Materials Institute received positive feedback at the spring meeting of the Industry Advisory Board for the Center for Bioplastics and Biocomposites (CB2), a National Science Foundation Industry—University Cooperative Research Center.

The projects, “Unlocking the Potential for Xylan-based Polymer Materials” and “Investigation of the Enzymatic Degradability of Glycolic Urethane Linkages Using Chromophore Probes,” are among nine that were selected by CB2’s IAB for research and funding in 2020. The other projects are being conducted at three other research sites, that, together with UGA, comprise CB2: North Dakota State University has three projects underway; Iowa State University and  Washington State University each have two. Updates on all projects were presented by researchers at CB2’s spring meeting, held virtually in mid-May.

Pushing toward greater sustainability

“UGA is very happy with the feedback we got from the Industry Advisory Board, which indicates the member companies are satisfied with our work thus far and that we are on-track,” said Jason Locklin, director of the New Materials Institute and the UGA site director for CB2.

Project updates and pitches for new projects are the two main agenda items for CB2’s spring meetings. The pitched seed projects are then shaped to benefit the greatest number of CB2’s member companies, representing many different industries: Ford, Hyundai, 3M, Boehringer Ingelheim, Kimberly-Clark, Shaw, Sherwin Williams, as well as bioplastic resin manufacturers and packaging manufacturers. Through annual fees, they help share the cost of developing the technologies produced by CB2’s research teams, with the goal of adapting the technologies. Each member company is striving for greater sustainability in its product line.

“I am excited about the seed proposals pitched by the industry members for 2021,” said Locklin. “The ideas represent technologies that are desired by many companies involved in CB2, and the ideas present both a good fit and an intriguing challenge for the variety of research expertise we have among the four university sites. These projects also represent tremendous learning opportunities for our students.” Project selections for 2021 will be finalized when the board meets again this fall.

Insight from industry

The two projects being led by UGA are good examples of research that could take years to exit a laboratory if industry was not invested—financially and hands-on— and awaiting a timely outcome. Having industry involved helps the researchers better understand its needs, including recognizing what’s readily available and cost effective. The xylan project, for example, is focused on identifying plant properties which may be useful in creating bio-based polymers for materials and products. (The glycolic urethane project is focused on developing faster methods for screening enzymes that will deconstruct polyurethanes, which will aid in the development of completely compostable high-barrier, multilayer packaging.)

Breeanna Urbanowicz, who leads the xylan project, has investigated plant properties, with a focus on xylan, for years. In her spring update to the IAB, Urbanowicz noted that in consultations with her industry mentors to discuss test results, the mentors helped her see potential in another abundant polysaccharide from plants, because it’s commonly seen in their industrial waste streams. Based on this insight, her team is now exploring two naturally existing biopolymers that possess potential for replacing petroleum-based polymers currently used to manufacture single-use plastic packaging. Urbanowicz is an assistant professor in the Department of Biochemistry and Molecular Biology, in the Franklin College of Arts & Sciences; she is based at the Complex Carbohydrate Research Center.

The xylan project, like all CB2 projects, is focused on non-food sourced materials for bioplastics. CB2 emphasizes use of agricultural byproducts, so that agricultural land is not utilized to grow crops for bioplastics and biocomposites.

Meeting held virtually due to COVID-19

The semi-annual meeting of researchers and CB2’s industry members was held virtually due to the COVID-19 outbreak. Faculty from CB2’s four research sites noted their work has been slowed by the virus, but forecasted their projects would quickly be on-track again once on-campus research ramps back up.

The UGA New Materials Institute’s participation as a research site for CB2 is supported by NSF Award #1841319.

Designing products for a better outcome following a useful life

Representatives from Shaw recently interviewed Jason Locklin, director of the UGA New Materials Institute, about the Institute’s research partnerships with industry and why the Institute focuses on single-use packaging as a means to reduce the mismanaged plastic waste that is accumulating in our environment. The UGA New Materials Institute is among 10 organizations being highlighted this year by Shaw Industries Group Inc., as part of the company’s new sustain[HUMAN]abilityTM recognition program.

Shaw Industries has partnered with the New Materials Institute to bring greater sustainability to their product line. The company also explores sustainability solutions with the Institute and its collaborators by being a member of the Industry Advisory Board for the National Science Foundation Industry & University Cooperative Research Center for Bioplastics and Biocomposites, known as CB2. The New Materials Institute serves as a research site for CB2, along with Iowa State University, Washington State University, and North Dakota State University.

Bioseniatic℠ Laboratory director discusses research on biologically-degradable materials

Evan M. White, an assistant research scientist at the UGA New Materials Institute and director of the Institute’s Bioseniatic℠ Laboratory, recently talked to WUGA-FM about researching and developing compostable materials designed for single-use packaging. White and his colleagues are developing plastic materials and products that may be broken down and metabolized by microorganisms in a variety of environments, from managed industrial compost to soil or sea water. Their emphasis is on replacing materials and products currently used to make single-use plastics, which comprise roughly 42% of all plastics produced globally, annually.

White explains the difference in materials described as “biodegradable” compared to materials being developed at UGA which are biologically degradable. His interview aired on WUGA’s Athens News Matters on Feb. 7, 2020.
