I agree any of this can be dealt with by sorting, cleaning (to make the plastic cleaner but not clean), and preprocessing by something like the MRF. The question becomes by the time you sort, clean, and preprocess the plastic, do you end up with recyclable plastic and if not does it become so expensive that it no longer makes sense to either run the machine (this is what JBI has proved emphatically so far, hence the change in business direction) or makes it very difficult to sell a machine with beneficial terms.
How about that laughable nonsense that we heard thousands of times that JBI could first excavate and then process RockTenn's dirty and wet plastic monofills?
Now we're hearing that they can't even process plastic that's never been buried, because it's not "CLEAN" enough.
