Hello dear Reprap community !
Long time reader, first time poster.
Few years ago I started experimenting with converting plastic scrap into usable 3D printer filament at home and today, I'm publishing a guide about that.
Cheap and home scaled focused. The process consists in sorting and cleaning plastic pieces taken from defective household appliances, grinding them to small granules, and feed those granules to a home made small extrusion line. After a quick post-processing step, the output filament can be used by a 3D printer to print new objects.
This is far away from being perfect but maybe some useful infos could be found inside the guide for those who are in the same kind of research.
Everything inside is open source.

I'm happy to share thought about it,
Have a good day,
