A new recycling process developed at the U.S. Department of Energy’s Critical Materials Institute (CMI) turns discarded hard disk drive (HDD) magnets into new magnet material in a few steps, and tackles both the economic and environmental issues typically associated with mining e-waste for valuable materials.

CMI expands research in tech metals as rapid growth in electric vehicles drives demand for lithium, cobalt04/11/2018
As increasing consumer interest in electric vehicles drives the demand for supplies of lithium and cobalt (ingredients in lithium-ion batteries), the Critical Materials Institute will begin new efforts this July to maximize the efficient processing, use, and recycling of those elements.
Researchers at the U.S. Department of Energy’s Ames Laboratory have designed and built an advanced model system that successfully uses very small quantities of magnetocaloric materials to achieve refrigeration level cooling. The development marks an important step in creating new technologies to replace 100-year-old gas compression refrigeration with solid-state systems up to 30 percent more energy efficient.
Paul Dabbar, the Department of Energy Under Secretary for Science, visited Ames Laboratory on Tuesday, March 27 for facilities tours and discussions with laboratory leadership and scientists. The tours and meetings highlighted the breadth and depth of Ames Laboratory’s specialization in materials science and engineering, including high-purity metals preparation, advanced powder synthesis, condensed matter physics, quantum materials, exascale computational development, catalysis, and chemical sciences research.
A new biochemical leaching process has been developed that uses corn stover as feedstock, and recovers valuable rare earth metals from electronic waste.
It’s nothing new to Iowans that corn and its byproducts can be used for high-tech applications ranging from bioplastics to ethanol. Using corn stover for what is essentially a mining process may seem like a stretch even for Iowa – the world’s biggest producer of corn—but the new process does indeed use stover as a key ingredient. The research was directed by the U.S. Department of Energy’s Critical Materials Institute (CMI)
