Hybrid/Electric Vehicles (EV/HEVs) will represent 7% of the global vehicle market by 2050. Lithium-ion (Li-ion) batteries, half the car’s cost, are safe while in use but hazardous when they enter traditional waste streams. By developing a closed loop recycling process, subsidies reduce consumer battery cost by 11%, and an energy storing electrical grid balances energy supply/demand, increases useful battery life by 100%, and increases grid efficiency. Green Battery Recycling technology recycles 90% of material value into new raw materials. Our closed loop process manages valuable hazardous materials responsibly, thereby decreasing cost, improving national security, and promoting environmental health.1, 6, 11

Rare earth magnets (REM) are powerful magnets that are commonly used in household appliances, wind turbines, and other technological processes. A growing shortage of the elements needed in order to make REMs as well as trade disputes between the countries exporting the materials cause fluctuating costs for both manufacturers and consumers. The goal of this project was to investigate ways to increase REM recycling rates in end of life (EOL) products and devise a plan to establish this practice in the United States since there are currently no systems in place. Through research of recycling practices in Europe and Asia, along with research of different magnetic separation processes, we have developed a plan to address this problem. We recommend that the recycling of REMs be integrated into already existing recycling processes with the addition of magnetic resonance damping to separate the magnetic materials from the basic ferrous scrap.2,3,5,6

Focused on material resources and reusing and recycling them, students blend engineering with humanities, collaborate with the NSF Center for Resource Recovery and Recycling (CR3), and work on projects sponsored by leading global corporations.
