Marie Perrin, 28, develops a method to recover europium from used lamps
Marie Perrin, a 28-year-old chemist born in Houston to French parents, developed a technology to recover rare earths, especially europium, from waste such as used fluorescent bulbs and neon tubes, which can contain up to twenty times more europium than natural minerals. The European Patent Office describes it as "faster, cleaner and more sustainable." Perrin founded the startup Reecover with her best friend from chemistry preparatory classes and with Victor Mougel, her former thesis supervisor at ETH Zurich, to scale it industrially.
In 45 seconds
- The method separates europium in a single step using sulfur-based molecules in solution, reducing chemical waste and energy consumption.
- The researcher founded Reecover with a friend specialized in finance and with Victor Mougel, her former thesis supervisor at ETH Zurich.
- Perrin is among the ten young inventors of the year selected by the European Patent Office; the three winners will be announced on June 18 in Reykjavik.
