Researchers at Empa have developed a new biodegradable material using the mycelium of the split-gill mushroom. The material is made up of the fungus’s own extracellular matrix, which gives it unique properties such as tensile strength and versatility. The material is completely biodegradable, non-toxic, and edible, making it suitable for a range of applications. The researchers have demonstrated its potential use as a living emulsifier, stabilizing mixtures of liquids that would otherwise separate. They have also used it to create thin films with good tensile strength, which could be used as a bioplastic. The material’s biodegradability and ability to actively decompose organic waste make it a promising solution for reducing plastic pollution. Potential applications include compostable bags that can break down organic waste, biodegradable moisture sensors, and even a compact, biodegradable battery. The researchers believe that their living material could have a significant impact on the development of sustainable materials and technologies. With its unique properties and potential uses, this innovative material is an exciting example of the potential of fungi-based technologies.
