My 3D printing scraps were the first thing I wondered about too.
I have a box or two of just scrap PLA because they said it was recyclable/biodegradable. Not much about just how specific the conditions needed to be.
It can't be that hard to homebrew some sort of extruder to remake the filament, can it? Who needs tolerances?

- jfoutz 3y agoI’ve looked at but never tried 2 things. 1, pla melts at about the same temperature as paraffin, people have used candle making kits to cast skulls or whatever. Seems neat to me. 2, similar trick, put the pla between two cookie sheets with weights. Heat to melting. This gives panels you can cut and incorporate into projects. Drawer bottom or robot body , that kinda stuff.

- jfoutz 3y agoI remember looking at these machines a while ago. Seems neat. I don’t have the waste volume to support the floor space. Very cool project though.

As in, dump laundry basket of PLA scraps into washer, add magic PLA enzyme detergent, push "PLA Dispose" button, and all of it stays out of a landfill.
