As reported in a previous blog this COES add on appears to use chemistry to enhance mechanical means.
"Ashland PTV M-5309 corn oil extraction aid is a proprietary, non-polymeric, liquid product that significantly increases corn oil production by improving the release of oil during mechanical extraction."
They have today issued a pr here. They "claim" a cleaner oil and up to three times previous production.
"The product has received the generally recognized as safe (GRAS) and Kosher certifications. Additionally, Ashland has a pending patent application for use of Ashland PTV M-5309 in corn oil extraction."
The corn oil extracted on the front end is for consumption and commonly uses potentially dangerous chemicals: Almost all (edible) corn oil is expeller pressed, then solvent extracted using hexane or isohexane - so the idea of using chemicals in extraction is hardly new.
Here are 24 things Ashland sells to the biorefining industry. HERE is their Corn oil site.

Kind of sounds like this additive makes POET's corn oil extraction pointless...
“The real beauty of the product is that refiners don’t have to change their process.”
"Added to the process after distillation, the extraction aid also reduces solids in the oil, resulting in a cleaner, higher-quality oil."
Is this a competing process with GERS technology? Is this an indication of the acceleration of developments in alternative fuel that will antiquate GERS technology? How can GERS compete in this intellectual arena with only 14 employees compared to hundreds at the bigger companies? Important questions for the future of GERS.
This appears to be something that may make it easier for GERS technology to get over the threshold for being an advanced technology. If it is true and if it does not add a dangerous chemical like hexane to the ethanol plant. This does not appear to compete with GERS, but rather needs the mechanical process of GERS. I would be surprised if GERS is not also working on something like this, a clean, non toxic chemical additive that helps to break the bonds . . .
A competeing process it is not. This additive works in conjunction with the patents. It's backend so it builds on Greenshift's methods. Notice how it said it's added after distillation and there's no need to change the process? This is bad news for Greenshift's competition, POET. They worked so hard to get around the patents and now thier VOILA is already antiquted and outdated by an advancement in technolgy that builds on Greenshift's patented process.
Winsness added: "we are aware of no practical method to recover corn oil from stillage that does not also rely on our patented corn oil extraction processes. We believe this to be true regardless of the type of equipment or chemicals used; or the upstream ethanol production conditions or temperatures; or the downstream processes used to strip free fatty acids or to filter recovered oil prior to refining. We welcome and expect innovation, however, we also expect any and all use of our technologies to be lawful."
EMPHASIS ON:
"regardless of the type of equipment or chemicals used; or the upstream ethanol production conditions or temperatures; or the downstream processes used ..."
They are standing firm that a license is needed from GERS, regardless of these other variations.
