If what you say was true they wouldn't have used words like:
CRITICAL FOR SUCCESS RIGHT MATERIAL VOLUME CONTRACTING FOR VOLUME COMMITMENTS THE RIGHT MATERIAL
Based on the company's statements that they can produce for a cost that's less than $10 per barrel, it's easy to understand that lowering the cost of shredding plastic is not "CRITICAL FOR SUCCESS" however getting the "RIGHT MATERIAL AND VOLUME" is.
Absolutely dead wrong on a massive scale.
There are costs associated with preparing the free plastic for processing. That's what they're talking about.
They will buy feed stock if and only if it lowers their costs.
