It doesn’t make a whole lot of sense to recycle plastics because each time they are sent through a screw extruder they lose some molecular weight.
Each new lot of pellets will become more variable in mw over time so properties eventually won’t meet specifications.
It’s better to heat the plastics to make producer gas.
I was taught this in about 1990 in Materials Science class.

Today’s soda bottle is tomorrows speed bump.
You can have a dumpster full of bottle glass, the highest consumer quality glass, and if some on throws in a piece of window glass (much lower quality) when that dumpster is recycled, it’s now only good for window glass.
