Meet the EMME team :
Matthieu Decuiserie, Operations Manager at EMME
Matthieu has just joined the EMME team as Operations Manager. He is responsible for maintenance, safety, and industrial environmental aspects within the project’s design phase.
Why did you join such a project?
“It’s a concrete opportunity to contribute to strengthening French mainland industry, especially in the crucial field of battery chemistry. During my 18-year career in industry in New Caledonia, I enjoyed working on forward-looking projects that allowed me to apply my expertise in process engineering. Joining EMME means putting myself at the service of innovation while continuing to learn and grow. Beyond the technical aspect, what convinced me was the ambition to develop an industrial project that sets a benchmark for social and environmental commitments. As a young father, this strongly resonates with my personal values.”
Who do you work with on a daily basis?
“Bringing a project like this to fruition with the highest scientific and environmental standards requires building a team of passionate professionals with international expertise. Engineers, researchers, technicians — each of us contributes our vision, experience, and specific skills. We share a common drive to progress and a strong solidarity that emerges whenever challenges arise. This dynamic environment, demanding yet human, encourages me to step out of my comfort zone and grow.”
What is your biggest upcoming challenge?
“Obviously, it’s successfully launching the EMME project while meeting all the environmental, societal, and industrial requirements we have set. It’s not just about developing innovative technology. We need to consider many factors — technical performance, regulatory compliance, economic viability, and social acceptance. Moving from concept to reality is a decisive step that demands strong teamwork, smooth coordination among project stakeholders, and meticulous planning. Agility will also be essential! It’s a demanding challenge, but one that gives full meaning to my commitment.”
