Bioplastic films from agri-food waste for sustainable packaging
Innovative bioplastic films created from agricultural and food waste using dynamic chemistry for sustainable packaging solutions. These films are self-healing and reconfigurable, offering enhanced strength, thermal tolerance, and barrier efficiency.
Overview
The University of Chicago presents an advanced solution for sustainable food packaging through the development of bioplastic films derived from agri-food waste. This innovation leverages dynamic chemistry to create adaptable bioplastic networks capable of reversibly altering their properties in response to stimuli. The resulting films are self-healing and reconfigurable, offering enhanced sustainability and functional properties such as increased strength, thermal tolerance, and barrier efficiency, making them ideal for use as single-use plastics.
Technical specifications
Our approach involves the chemical modification of polyhydroxyalkanoates and polysaccharides through a solvent-free process. By incorporating vinylogous urethane dynamic bonds, we create bioplastic networks that offer unique adaptability. The films are designed to have mechanical strengths comparable to commercially available options while utilizing upcycled food waste, enhancing their environmental appeal. Future validation includes the use of AI/ML algorithms to optimize formulations, aiming to produce films with superior mechanical and barrier properties.
Technology readiness level
Currently at Technology Readiness Level 3, this technology has been successfully upscaled for the acetoacetylation process, with ongoing efforts to improve film performance and manufacturing efficiency. The next steps involve high-throughput experimentation and AI-driven optimization to refine the films' properties further, facilitating their transition to commercial applications in sustainable packaging.
About University of Chicago
The University of Chicago is a private institution that brings together the power of 140 institutes and centers including an NCI-designated Comprehensive Cancer Center, a microbiome focused center, two U.S. Department of Energy National Labs (Argonne National Laboratory and Fermi National Accelerator Laboratory) and the Marine Biological Laboratory, making it a truly powerful research and development enterprise of over 15,000 faculty and research staff. UChicago is home to the Pritzker School of Molecular Engineering, launched in 2011 as the first and only engineering school in the U.S. focused entirely on molecular engineering with one of the major focused areas in immunoengineering, and a core partner of the Chan Zuckerberg (CZ) Biohub - Chicago. Researchers at UChicago have pioneered breakthroughs including discovering the link between cancer and genetics, establishing revolutionary theories of economics, and developing tools to enhance urban schooling. UChicago researchers are at the forefront of fields ranging from quantum computing, data science and artificial intelligence, to the modeling and synthesis of advanced materials, to oncology and neuroscience.
