Recycling Neodymium Magnets from Computer Drives with Ammonium Chloride

German researchers are developing two chemical processes to extract neodymium, iron and boron from scrap computer hard drives. The work, carried out under the European Union NEO-CYCLE project, aims to recover rare earth elements locally to supply motors for each new electric vehicle and wind turbine without relying on overseas refining.

Vienna Chemists Turn Discarded Plastics into Solar Water Harvesting Sponges

Materials chemists at the University of Vienna have developed a method that converts aromatic plastic waste into functional polymer networks capable of extracting water from the air. Discarded packaging and consumer plastics capture ambient humidity and release liquid water when exposed to moderate solar heat, offering a circular approach to resource recovery.
