From these view points, we review recent literature on recycling of rare earths from various rare-earth scrap materials, such as permanent magnets, phosphors, secondary nickel metal hydride batteries, polishing powders, optical glass, and catalysts. The review is concerned initially with each recyclable product and then on each method used in recycling. [Pg.162]

Lanthanum, yttrium, and gadolinium are used in optical glasses with high refractive index and low dispersion. The annual demand for La203 for this purpose in Japan was 502 tons in 2006 none of this glass is recycled (JOGMEC, 2008). [Pg.202]

The manual sorting method is labor intensive and requires operators to monitor an assembly line and sort out clear plastic bottles (PET) from the milk containers (HDPE) and colored plastic containers (LDPE, PP, PVC). The automated method can employ one of several analytical techniques, including X-ray fluorescence, mass spectroscopy, Fourier Transform Near Infrared (FT-NIR) spectroscopy, Fourier Transform Medium Infrared (FTIR) spectroscopy, or tribo-electric analysis, on the recycled plastic materials. The state of Rhode Island has a single stream process to sort out the recycled materials with optical sorting technology. The recycled materials include cardboard, paper, glass, metal, and plastics (Rhode Island 2013). [Pg.116]
