Kanazawa University-led researchers recycle rare-earth elements from spent fluorescent lamps by chemical/mechanical treatment

NOVEMBER 4, 2018
A team led by Kanazawa University in Japan has developed a cleaner method for the recycling of several rare earths (REs) such as yttrium (Y) and europium (Eu) used as phosphors in fluorescent lamps (FLs). End-of-life FLs are a potentially huge source of REs, but harsh and polluting processes are needed currently to extract these metals from the spent phosphors.
