Researchers developed an environmentally-friendly insulation material by growing mushroom mycelium (Ganoderma lucidum) on cocopith, a waste product from coconut fiber processing. The resulting biocomposite has thermal insulation properties comparable to commercial insulators like Styrofoam and polyurethane, but is completely biodegradable and made from agricultural waste. This innovation addresses waste management problems while creating a sustainable material for thermal insulation in buildings, food processing, and industrial equipment.
