Interpretive Summary:

Technical Abstract: There is a need for biodegradable alternatives to the inert plastics and expanded foams currently used in in manufacturing processes and device components. The material focused on in this report is a bio-composite patented by Ecovative Design, LLC. The bio-composite utilizes the fungus mycelium to integrate various agricultural substrates or substrate blends to create a product for a variety of uses. Currently, this material is marketed as a degradable alternative to polystyrene packaging. This report details the results from several studies evaluating the material for applications, both potential and actual, such as packaging, biomedical, acoustic absorbers, and one-use-cushions for tsunami buoy deployment. The presentation will report on results from bio-composites samples manufactured using different fiber-fungal strain combinations. Physico-mechanical properties, acoustic performance, and fiber blend selection optimization of the composite materials are characterized. The results indicate a 100% biodegradable material that has a soft outer surface with high elasticity, light weight, buoyant, and flame and water resistant depending on mycelium growth.
