Report New NSF Center

Report New NSF Center for Bioplastics and Biocomposites launched Access to world-class facilities and researchers and accelerated development of new environmentally sustainable products and processes are two of the many reasons bioplastics industry leaders, like 3M Co. and Archer Daniels Midland Co. are investing in the development and evolution of the new (US) National Science Foundation (NSF) Industry and University Cooperative Research Center for Bioplastics and Biocomposites (CB 2 ). A partnership among universities, industry and government, CB 2 was launched last November and is led by Iowa State University and co-located at Washington State University. It is funded through industry and NSF support. David Grewell, professor of agricultural and biosystems engineering and chairperson of the Biopolymers and Biocomposites Research Team at Iowa State, is the director of CB 2 . Grewell says Iowa State and Washington State University have the expertise and experience to successfully operate and grow a bioplastics and biocomposites center. State-ofthe-art research facilities at Iowa State and Washington State are designed and equipped to develop, test and scale-up new biobased materials and processes. “Iowa State is an established leader in the area of biobased products and Washington State has a strong history of research and inventions in natural fiber polymer composites. Both universities have good relationships within the industry,” Grewell said. Kevin Lewandowski, lead research specialist at 3M Co. and chair of the CB 2 industry advisory board, agrees. “We’ve been involved from the beginning discussions of creating the center. And Iowa State is a school at which we recruit heavily,” said Lewandowski. He says 3M’s membership in the center will positively impact 3M sustainability goals. “We’re interested in replacing very common polymer products that are currently derived from oil, such as plastic films and packaging materials. We’re also interested in more high tech materials such as composites, where we need high performance and are also looking to improve sustainability attributes. 3M’s product portfolio is pretty widespread, so there are a lot of areas where we could leverage more sustainable solutions,” Lewandowski said. Benefits to industry members of CB 2 are many, says Michael Kessler. He is a professor, the Berry Family Director of the School of Mechanical and Materials Engineering and the CB 2 site director at Washington State. “Through their votes, industry members select the research on which the center will work. They get access to the facilities of the universities doing the research. They have access to scientists and students whom they may want to recruit into their companies and who are trained in the field of bioplastics and biocomposites. Networking with other member companies and access to all the technical data and intellectual property that’s developed are also benefits,” Kessler said.

Higher R-values mean greater insulating power. 2 ASTM E-681 To learn more about Honeywell Solstice LBA, visit © 2014 Honeywell International Inc.

Join us to explore new opportunities. Volume 6, November 2014 Grewell and Kessler are principal investigators on one of the center’s current projects aimed at filling a knowledge gap. In the past, the team has characterized the welding of various rigid polylactic acid (PLA) films for such applications as packaging. However, there is no information on the ultrasonic welding of rigid PLA or polyhydroxyalkanoate (PHA) components. Ultrasonic welding is one of the most common methods to join plastics because it is fast, efficient and easily automated. Their research will produce knowledge of bioplastics’ (PLA and PHA) weldability and sensitivity to welding parameters, including temperature sensitive activation energy. Another of the center’s projects is focused on the development of biorenewable thermoplastic elastomers. This project will bring to market renewable thermoplastic elastomers that are cost competitive with their petrochemicalbased alternatives. Example applications include, but are not limited to, adhesives, films, packaging materials, sealants, additives and/or rubbers. In addition to new product and process development, center researchers are developing a life cycle assessment tool for screening trade-offs among processing costs, environmental impacts and end-of-life options for products. Kurt Rosentrater, assistant professor of agricultural and biosystems engineering at Iowa State and a CB 2 researcher says biobased materials come from renewable resources, but that is not the only measure of product sustainability. “Just because we can utilize biological materials doesn’t necessarily mean that it’s a greener product. What happens when it reaches end of life? Can you recycle it? Does it degrade? Do you put it in a landfill and it sits there for hundreds of years like a lot of the other materials, or will it actually break down in the soil, decompose and become fertilizer? Or, if it does break down, what kind of emissions are there going to be, based on what else is mixed with the biological materials?” said Rosentrater. He says one of their first steps will be to determine where, in a product’s life cycle, to begin and end the environmental assessment. CB 2 member companies have access to performance data for biobased materials developed through the center. Once the life cycle assessment tool is developed, they will have access to it as well, allowing them to compare costs, energy demands, environmental impacts and end-of-life options for the biomaterials developed via the center. Lewandowski says he hopes more companies will become members of CB 2 . “You get a better return on your investment as more companies join. It allows more research to be funded which can benefit multiple companies,” said Lewandowski.
