Mushroom Material is a sustainable and home compostable mushroom-based packaging material that has the same protective properties as polystyrene/styrofoam but naturally degrades within months. It is customizable to any shape, size, density, hardness, and surface finish of the product. It has a limitless sustainable supply and is also fire resistant and waterproof. We can match the mechanical properties of polystyrene and replace any existing parts with a sustainable Mushroom equivalent.
