How consistent does your feedstock have to be? If you're using PLA and just want to not landfill your supports and brims and so forth, you can pulverize it in a blender from the discount store. You'll wind up with all different granule sizes, though.
Edit: Actually, if you drill down into the description of the individual parts they do explicitly say it includes one high compression feed screw meant for reclaiming waste plastic. Obviously you still have to pulverize it somehow first. The other feed screw it comes with is for making filament out of pellets. So, both.
I don't think buying all this equipment is better for the environment than just burying the scrap material in a landfill.
But it might be more fun.
Or more tedious 😀
