Unfortunately they didn't say how much plastic they processed in an hour and what the conversion rate was and there's no indication of the costs involved and they were limited to one type of plastic so there had to be some sorting done and maybe they even had to wash the stuff.
But you gotta start somewhere :o)
Maybe someday someone will figure out how to create "a process that derives ultra-clean, ultra-low sulphur fuel, directly from unwashed, unsorted waste plastics" and do it profitably. PTOI sure as heck couldn't do it.
