Failed print and waste filament recycling

[DavidR8]

Ran across this today. If a person had a LOT of failed prints of bags of 'poop' from colour changes this could be a cool project.
Of course a person would need some way to shred the material...

A paper shredder - the kind that makes chips, not strips, does a great job. Big lumpy bits need to be smashed a bit first.

Just use the Wife's food processor. (don't do that.....)

A filament extruder almost seems like a necessary purchase if you own a Bambu/AMS and print a lot of multicolour prints. Sure you can tune them better for less poop, but they still generate a lot from what I hear about them.

The pooping is not insignificant but I am producing far less waste with the Bambu than I did with the Ender 3 simply because of very few print failures.
And I am printing orders of magnitude more stuff.
I can't imagine a home hobby printer generating enough waste to justify the nuisance and expense of trying to make your own filament unless you're running a print farm.
And I think you'd still have to be bad at it.
