Despite the fact that REEs are vital to modern technologies and society and are among the most critical of the critical elements, commercial recycling of rare earths is very limited. Typically, only around 1% of the REEs are recycled from end-products, remaining goes to waste and are removed from the materials' cycle (Jowitt et al. 2018 ).

Commodity Rare earth elements, or REEs, are neither "rare" nor "earths." REEs are metal elements that are relatively common in the Earth's crust. The label "earths" was used as they were originally discovered as oxide compounds. They were described as "rare" as the minerals in which they are found are not often concentrated in geologic …

Most REEs are not as rare as the group's name suggests. They were named "rare-earth elements" because most were identified during the 18th and 19th centuries as "earths" (originally defined as materials that could not be changed further by heat) and in comparison to other "earths," such as lime or magnesia, they were relatively rare.
