The problem with the plastics industry, the reason so many people are fed up with it, is the 'understanding' you speak of tends to lag their industrial application by many years. So we end up with a whole lot of "X is now known to have bad properties, but we already use too much of it to change now." For instance, virtually every thermoset plastic in use today is impossible to recycle, but there seems to be no going back. Their use continues to proliferate.
