Sounds plausible but of course there are lots of details to be worked out including how to recover the magnetite and how much it costs But it's from September

But it's from September 2019. Does anyone know if anything has happened with the idea in the last 18 months.
- iagovar 6y ago> how to recover the magnetite Won't that happen with the same magnet?
- kwhitefoot 6y agoPresumably the magnetite is very finely divided and intimately connected to the material it is removing from the water; to reuse it surely one must detach the magnetic material from the plastic. It is not obvious to me that this is easy to do with high effectiveness. Presumably we do not want finely divided magnetic material to escape into the environment or for it to be included in the recovered plastic.
