Yup -- another business trick is in McDonalds -- the company that supplies the beef in Ireland is called "100% Irish Beef" and thus they put that on the packaging even if the beef doesn't come from Ireland.
I've seen this don't with the equivalent of "100% recyclable" as the name of the company to pass the product off as environmental.
However the main problem is still consumer knowledge of whats recyclable. If people think there is a small chance that something is recyclable they will throw it in the recycling bin -- this is the complete wrong approach. Put everything in the trash unless you're 100% sure it's recyclable. Otherwise you'll "contaminate" the whole batch like throwing a bad apple in on top of a barrel of good apples.
