The increasing demand of rare earth elements and platinum group metals requires alternative approaches for their recycling from waste. Decades of fundamental laboratory research on biosorption area have emphasised that bio-based materials (biosorbents) display high and versatile potential of metal preconcentration. However, the …
Rare-earth (Re) substitution in BiFeO${}_{3}$ can result in a tuning of the crystal structure from ferroelectric R3c to antiferroelectric Pnma, making (Bi,Re)FeO${}_{3}$ among the best dielectric materials for energy storage. Using a first-principle-based atomistic approach, the authors predict that playing with the Re elements and varying the …

Rare earth magnet recycling is about so much more than sustainable data centers. ... "There is an opportunity to make magnet design constant between generations so the reuse process can scale ...
Rare earth elements (REE) are widely used in high technologies, medical devices, and military defense systems, and are especially indispensable in emerging clean energy. Along with the growing market of green energy in the next decades, global demand for REE will increase continuously, which will put great pressure on the current REE …
The boom in technological advances in recent decades has led to increased demand for rare earth elements (REEs) (also known as rare earth metals) across various industries with wide-ranging industrial applications, including in the clean energy sector, but with some environmental, economic, and social footprint concerns. This paper reviews …
Rare earth elements (REEs) are a group of 17 chemically similar metals, which got their name because they typically occur at low concentrations (between 0.5 and 67 parts per million) within Earth ...
The existing recycling infrastructure for fluorescent bulbs makes them good candidates for rare earth recycling, many experts say. With price pressures off, at least for now, and few laws requiring recycling, there is little incentive to try to get the materials back. As of 2011, less than 1 percent of rare earths were recycled.

Recycling and reuse of rare earth metals are a promising field (Weber and Reisman, 2012) because these also save energy used in mining and processing, conserve resources, and reduce pollution and greenhouse gas emissions. Consistent with this goal, it is important to undertake an analysis of the socioenvironmental and socioeconomic …
For every ton of rare earth produced, the mining process yields 13kg of dust, 9,600-12,000 cubic meters of waste gas, 75 cubic meters of wastewater, and one ton of radioactive residue. This stems from the fact that rare earth element ores have metals that, when mixed with leaching pond chemicals, contaminate air, water, and soil.
