The diverse properties of rare earth elements have seen broad and growing applications that are environmentally benign in traditional and new environmentally benign products such as hybrid cars and wind mills, magnetic refrigeration and so on. This study reports the results of a life cycle assessment study into rare earth elements that has not been given adequate attention. Preliminary results indicate that REEs tend to have very high GHG impacts and resource depletion potential. Also, the numerous waste streams generated in the processing can be toxic and may contain harmful radioactive substances.
