Soylent Green is plastic!

Is there any of this ”bacteria converting plastic to fuel/food/neutral stuff“ actually applied anywhere at scale under economically reasonably conditions?

> The researchers took PET plastic, discarded corn plant stalks and leaves, and other biomass and put it through a proprietary process called oxidative hydrothermal dissolution. Created by SIU Carbondale Geology Professor Ken Anderson, this method uses water and oxygen at high temperatures and pressures to break down tough material into microbe-accessible pieces. Then, those pieces are fed to the programmed yeasts, which transform them into a variety of new food ingredients, including proteins, fats and acids. Finally, the researchers add fiber, starch and sweetener to the mix and extrude it through a 3D printer, forming protein-rich cookies dubbed µBites (pronounced "microbites").

It kind of sounds like they made food out of corn plant stalks and leaves and "other biomass", added fiber, starch, and sweetener, but then just polluted the product with processed waste plastic as an additive. If this really is just using trash as a filler in actual food that's pretty dystopian. I'm sure companies would happily line up to sell their industrial waste products to food companies as an additive, but I'm not seeing the appeal in this for consumers.

Please don’t add the byproduct to my food, put it in the ground to decompose
