The long time viewers of PO.com are reminded of the project in Missouri, now run at some level by Con Agra, which supposedly had constructed a plant to convert "turkey offal" a.k.a. byproducts and various other waste items, into something that approaches crude oil.
Aside from some minor issues such as an incredibly foul odor, and the second law of thermodynamics, they thought it would work. They had the idea that they would build their plant next to a Tyson Foods turkey plant so as to get the "cheap" by products.
To make a long story short, Tyson decided that they could make more money selling the "offal" to local reprocessors, who presumably turned it into some other useful material, such as turkey food (ugh) rather than give it to the fledgeling plant next door to have it turned, by thermal depolymerization, into "oil".
There is a long thread on this project.

So, Tyson's "commitment", if any, to this idea, is only as deep as the next quarter's balance sheet.
