"A company with a plastic waste stream doesn't need the process to be "profitable". They just need it to be more cost effective than their current operations."

We just have a slight difference in semantics. If it's more cost effective then it will be more profitable owning the processor than without. Incrementally, it would be profitable.

There's a parity in that a potential customer paying to landfill the needed plastic could instead have paid JBI to take it and JBI could then have produced the exact same fuel at JBI's facilities which could be produced at the customer site. So far JBI hasn't found any opportunities.

It literally boils down to one thing--either the process transforms material into another material of higher value thus adding value...or it doesn't and the process is completely worthless. That includes the possibility of transforming something with a negative value like garbage into something which is less costly to dispose. So far JBI has come up with nothing after five years.
