London-based startup Aeropowder has shown the way by creating Pluumo - a high-performance insulation material, that not only makes better use of surplus feather waste, but also gives a sustainable alternative to packaging materials such as polystyrene. Deliveries are playing an increasingly important role in our society. Packaging must be used to keep goods safe during transport. Especially temperature-sensitive items, like chilled food ingredients or pharmaceutical goods. Pluumo actually outperforms the required insulation performance of expanded polystyrene while being created from a natural waste material. Wishing to make Pluumo fully compostable, Aeropowder contacted Biobag to test compostable and biodegradable film for the lining of the feather material.
