3d printing recycled filament


I was wondering what are the types of plastic suitable for making your own filament.
I have been collecting “ocean plastics”and I live in Edinburgh.
I have been looking everywhere for an extruder machine I could use for melting the plastic into new filament.
Are there any companies you can send your plastic to for them to make your filament?


There are quite a lot of topics on the community about 3D filament printing, have a look here http://onearmy.world/community/forums/search/filament/
