  • Lithium-ion battery recycling with the molten metal reactor (https://youtu.be/bXnt88Opu7s).  In this video, Kathriona Devereux interviews Dr Frank Riedewald on the RecEOL project see: https://www.youtube.com/watch?v=bXnt88Opu7s
     
    The interview is part of RTE’s “10 Things to Know About” science series, specifically about the Circular Economy, aired in Dec. 2022. The RecEOL project proves that a patented recycling process for waste printed circuit boards, lithium-ion batteries and aluminium-laminated plastics is economically viable and environmentally sustainable. The process uses a molten metal reactor to render lithium-ion batteries safe and makes the residue materials available for recycling in a safe, fast, and environmentally sustainable. The research was undertaken at UCC and the Tyndall National Institute (see the RecEOL website for more information).
