"I personally put unsorted mixed multicolored waste plastic into the processor."
So what?
My point, which you seem to have missed twice now, is that the suppliers of plastics are obligated to provide plastic that falls within the description of acceptable material according to the Air Permit. Hence, JBI is obligated to review the material to assure that it met the requirements and have no obligation to do any sorting of their own. What you put in the machine was unsorted by JBI, but it is SUPPOSED TO BE either Polypropylene (PP), Low Density Polyethylene (LDPE), or
High Density Polyethylene (HDPE)......or any combination thereof.
