These are cool, but I highly doubt anyone uses theirs regularly. What we need are makerspace-backed hyperlocal recycling projects. A much more expensive but much more effective method to recycle the same PET bottle would involve a plastic shredder and proper filament extruder. And old 3D prints? Sort them by color and material, they can go through the exact same process. Pulltruders can still be a useful tool, but more for education and spreading awareness than a practical source for filament.

Doesn't this just ensure you're 3d prints can't be recycled from regular trash pickup?
