Compostable hydrocarbon polymers, composites, and articles anaerobically biodegrade in landfills in a relatively short time. Composite polymeric articles and sheets such as indoor or outdoor signs, billboards, banners, images, protective barriers, backdrops and wall coverings have very useful service durations and yet are landfill biodegradable.
