I have a neighbor who was looking at those plastic boards some people will use instead of wood for a patio. He goes to the factory for this big presentation with an audience and they start talking about the boards being made from recycled plastic. My neighbor wants to know how much recycled plastic was in each board...the guy gets evasive and the neighbor presses him, and come to find out it was the bare minimum legal requirement to label them as being made from recycled material. It was some stupidly low amount, like a single water bottle or plastic bag per batch.
