Here's an example of RECYCLABLE hydrocarbon-only plastic that took me a few minutes to find for $70/ton in Canada. $500/ton? Please. And I didn't even bother searching for the non or difficult to recycle kind.
In addition, I found others on that RECYCLING website for .04 and .05 per pound. So, with barely even trying, your $500/ton insistence is almost as shallow as claiming there isn't a market for diesel fuel made from plastic. With just a few minutes of effort, I brought your over-inflated $500/ton claim down to $70/ton, your claim being off by 614%.
On another side note, I find it interesting that the scrap industrial waste plastic was packed in Gaylord boxes. Why? Because it was falsely claimed after the P2O video from JBII that anything packed in a Gaylord box must be brand new plastic from Gaylord's. I thought that was laughable when I first heard it, and now it's proven.
