A short interview with
Nora Bartolome Gutierrez
-
Nora is working part time as Scientific Project Manager at the Swiss Battery Technology Center, from the Switzerland Innovation Park Biel/Bienne in Switzerland and part-time as Scientist at the Technology and Society Laboratory at Empa, the ETH-domain institute of materials science and technology. In both groups, her work focuses on several projects related to the recovery of key elements from end-of-life (EOL) lithium-ion batteries. In addition, at Empa she works on the recovery of critical raw materials from EOL vehicles. She pursues both themes with the vision to implement a circular economy approach of these complex waste streams. Her work combines the coordination and implementation of different experiments at lab and pilot scales. Another important role at Empa is on international cooperation where she is supporting the group research component.
Previously, she obtained a PhD in Environmental Science from ETH Zurich (Switzerland) and did several PostDocs in the area of soil, water and sediment monitoring from contaminants and the study of remediation techniques. All these experiences brought her to work at Agroscope (Switzerland), Universidad de Heredia (Costa Rica) and Standorf University (USA).
Can you tell us about your professional journey and how you got started in this field?
My background is in Chemistry, and from the beginning, I was drawn to projects connecting chemistry with environmental and sustainability challenges. During my PhD and postdoctoral research, I focused on contamination in soil, water, and sediments, which deepened my expertise in environmental chemistry and sustainable solutions.
In 2020, I joined Empa, the ETH-domain institute for materials and technology, as a chemist working on the recycling of lithium-ion batteries and electronic waste. This was a shift that aligned perfectly with my passion for sustainability and innovation.
After several fulfilling years at Empa, I started my work at the Swiss Battery Technology Center, where I continue developing sustainable recycling processes for lithium-ion batteries, an area that is both scientifically fascinating and vital for accelerating the global energy transition.
Have you ever doubted your abilities and why?
Yes, there have been several such moments in my career. One of the biggest challenging moments was the transitioning from working on environmental contamination to focusing on recycling. It was a significant shift, but it turned out to be a really rewarding one.
Although it hasn’t always been the case, I’ve been lucky throughout my career to work on different occasions with fantastic group leaders who supported my growth. They often looked beyond my weaknesses and gave me the space and confidence to develop my strengths. That kind of environment makes such a difference, it really shapes how you grow as a professional. I believe that finding the right people around you is one of the most important factors in building a successful career.
Did you ever have the impression gender was an important factor on a raise, promotion, or key assignment?
Yes, on several occasions. I have felt that women often have to work harder to prove their abilities, and I have sometimes encountered inappropriate comments. Gender imbalances are still evident, especially in higher-level positions. What I find challenging is the lack of role models I can truly relate to, people who not only succeed professionally but also balance family life and lead with kindness and empathy. One of the thoughest moments in my career was returning to work after maternity leave. The first year was particularly demanding, with sleepless every night and the need to pump at work, which then made my workdays shorter. It was a period that required significant physical and emotional adjustment.
During your career, have you ever been mentored?
I’ve receive great mentoring on the scientific side of my career, but not as much when it comes to leadership development. That’s an area I’m really interested in exploring further. I know there are some excellent programs available, and I’d love to take part in one. Although it would likely need to be something I do outside of my regular working hours.
If you could give some advice to your younger self or other girls, what would that be?
Trust yourself, that’s essential for professional growth. Leadership isn’t about perfection; every leader has both strengths and weaknesses. What matters is learning from their strengths and taking what aligns with you, without focusing on their weaknesses. We all bring unique qualities to the table, and when we lead or work with humility and honesty, there’s room for everyone to thrive.
