Sustainable Chemist Marie Perrin Revamps Rare Earth Recycling
Marie Perrin innovates in the field of rare earth element recycling, aiming for a cleaner, more sustainable process for future use.
Hey there! Let's chat about a game-changer in the realm of green technologies. Meet Marie Perrin, a French-American chemist who's found a clever way to recycle rare earth elements (REEs) without stirring up a toxic storm!
REEs are essential for modern marvels like smartphones, laptops, wind turbines, and electric cars. However, their extraction processes can leave a colossal environmental mess. One tonne of REEs could generate up to 2,000 tonnes of radioactive waste, yikes!
But worry not – Marie Perrin's here to clean that up. At ETH Zurich, she whipped up a snappy, scaleable method to recover europium from cast-off fluorescent lamps, without the environmental toll of conventional methods.
"Today, I'm bringing to market a technology I developed during my grad studies on recycling rare earth elements," she beams. "They're in your phone, in your computer, and in a lot of green technologies, like wind turbines and electric cars."
"We have a solution… to source these metals from the waste we produce," she declares.
This ingenuity netted her a top spot among the European Patent Office's 2025 Young Inventors Prize's Ten Tomorrow Shapers.
A Sustainable Golden Solution to Toxic Waste
Perrin's patent-pending process kicks off by taking apart lamps safely to extract phosphor powder and knock off mercury. The powder dissolves in acid, then pairs with sulfur-based molecules that trigger a redox reaction, voila! A golden europium-rich precipitate forms while elements like yttrium remain in solution. The solid gets filtered, treated with ammonium oxalate to regenerate the extractant, and finally morphed into usable europium oxide.
Best part? This process scrimps on toxic solvents and rolls out a closed-loop reuse of chemicals. "[Our invention] allows us to separate these elements more efficiently," she clarifies. "We're not tossing critical metals in the bin!"
A Childhood Passion Turned Global Mission
Born in the Land of the Free and bred in Toulouse, Perrin caught chemistry's bug from a young age – with parents in the science field, how could she resist?
"My mom is a chemist, and she shared her passion for chemistry, which really guided me in my studies afterwards," she muses, reflecting on her youth.
Perrin's PhD at ETH Zurich began with a splosh on water purification rather than REE separation, but a switcheroo came early on when she, together with PhD supervisor Professor Victor Mougel, stumbled upon the potential of the molecules they were working with for REE separation.
Empowered by ETH's Technology Transfer Office, Perrin filed a patent application, published her findings in journal Nature, and teamed up with Mougel and long-time friend Maria Pujos to launch REEcover, a Swiss startup.
Even though REEcover's green credentials have won them admiration, the road hasn't always been a sunny stroll. "We courted many companies but initially struggled to make an impact," Perrin recalls. "We soon realized that many industries don't have a say in their supply chain."
A Leap Towards New REE Sources
Initially concentrating on lamps, REEcover's eyeing new horizons to recover REEs from motors in electric vehicles and electronic gadgets. They're working on proof-of-concept studies to tailor the method to other waste streams, encouraging industries to embrace a circular model.
For Perrin, this isn't science for science's sake. "Our generation faces many challenges, from global pandemics to climate change," she asserts. "If you've got an idea, be bold, be creative, and keep pushing the limits of human knowledge!"
