You're forgetting a number of things: 1) there is plenty of optimal plastic which can be obtained without much effort; 2) they save tipping fees; 3) they save expensive landfill space (thus the environment); 4) they create usable fuel that can be used their plants and in fleets (eventually); 5) tax benefits; 6) positive publicity
All of these things will assist making processors extremely viable (especially Waste Management Companies - and there are lots of those around the world).
While your questions and concerns are logical and realistic they are, IMO, stuck in the here and now. Everything humans have invented from the stone ax to social websites has changed dramatically as the knowledge gained from using them is reapplied. The first planes didn't have overhead storage and didn't come with a mid flight meal. Things worth doing always evolve and strangely enough there are almost alway people willing to get invloved in the early stages of a new idea or product and take part in that evolution.
IMO JB is a horrible businessman (inventor types often are), much money has been wasted and, many mistakes have been made. I wish that wasn’t the case but I can’t change it so can either move on or choose to believe in the future. I choose to believe in the future because at the center of the JBII soap opera I think there is a fundamental process that works better than those before and around it and it appears to be scalable to a commercially viable process.
Is P#3 fully ready for primetime – no. Will P2O be adopted by all that might benefit or be interested in pyrolysis – no. That said I believe there are people/companies that will be willing to “get in early” and be a part of the evolution. Accordingly I agree with stoker11’s recent statement:
"The “brain” of the process is a significant custom-programmed, data acquisition and control system (Fig. 8). Due to the unique nature of the process, thermocouples, pressure sensors, a scale, an oxygen sensor, level sensors, and proximity sensors were installed throughout the system."
"Process safety is designed through various levels of hardware installed to ensure proper and safe operation. Early triggers for potentially unscheduled events are monitored by chemical operators, through the software managing the process. Risk is greatly reduced by operating the process at slightly above atmospheric pressure."
Burst disks are a last resort... Its the embedded ice from being left out in the elements that caused problems last year, and testing HTF for water or contaminants is now happening.
Completely false... MRFs do this separation all day long, and all waste management companies and many municipalities have MRFs.
