Look at the price of scrap plastic, the plastic which PTOI needs as feedstock. It's not free since there is a robust market for scrap plastic in the recycling market. To make diesel or another carbon-hydrogen fuel, the only plastics which work are LDPE, HDPE and PP. That has a cost.
Pound for pound, the scrap plastic needed by PTOI costs about much as diesel!! It also costs money to process the plastic. It's a value destruction process.
I pointed this out over ten years ago. PTOI's process has zero commercial value. The continual failure over that time should drive that point home as well. Richard Heddle isn't being honest with shareholders either.
It's impossible PTOI founder John Bordynuik just forgot to do the math. He knew it was worthless but he pumped it anyway so he could get rich selling shares.
