I am not opposed, assuming there isn’t a severe quality concern. I would rather like a way to recycle my waste plastic. There isn’t really anyone local that will recycle PETG or PLA.
@Rutty there is a way first cut the plastic then use a blender on ice crush but be sure its normal plastic second it has to be sorted by thermodynamics & shade of color
PET is used in plastic water bottles, PETG is considered a contaminant and typically not part of the recycled waste stream, at least in the US. Same for PLA.
Although as you noted to pelletize plastic a blender would be a good place to start. The question then becomes what do you do with the pellets of plastic?
From my understanding it takes a system like this
https://www.filabot.com/products to produce filament from waste plastic. That’s not to say you can’t used the pellets in some other way.
