A Biodegradable Structural Composite Made from Lobster Shells?

On this episode, David J. Neivandt and Greg Simms join the show to discuss their research work developing a sustainable, biodegradable composite material derived from waste lobster shells and a natural binder, engineered for high mechanical performance. Collaborating with the Advanced Structures and Composites Center at UMaine, their team has established a pilot-scale production line for this material, which features compressive strength greater than concrete and flexural strength surpassing eastern white pine lumber. From a sustainability perspective, the composite has the potential to replace single-use plastics in applications where the item needs to maintain structural integrity for a short period and then biodegrade rapidly at the end of life. Team NRG’s recent work is moving them towards the ultimate goal of using the composite to construct temporary disaster shelters. You can find more episodes at https://compositesweekly.com.
