There are options out there to get plastic recycled, a part of industrial processes.
Precious Plastic: Very interesting movement. I only need space, time and some money, not too much, to do one of them. Really, i want to do it…
A gay I meet in maker faire BCN, Mahor,designed a pellet extruder for 3d printing machines, directly from plastic flackes! I’m following him, seems also a nice option. Just a little shredder needed…. the one from precious plastic would be fine!
Also, David, from 3DSeed Fab Lab, in Cerdanyola, has interesting projects about it. He was creating a big format printer with Mahor extruder. Will see what happens!
