The word “nuclear” often carries a cold and dangerous connotation. Yet at the same time, nuclear science—often called a “comprehensive science”—has generated countless advanced research achievements across diverse fields such as physics, chemistry, engineering, and biology. For many years, we have stood at the forefront of such nuclear research, engaging with a wealth of extraordinary technologies. However, one question has always lingered in our minds:

Why do so many of these remarkable technologies end without ever leaving the laboratory?

That question became our starting point.
Emulsion Flow Technologies Ltd. is a startup founded in April 2021 to bring to society the innovative solvent extraction technology “Emulsion Flow,” born at the Japan Atomic Energy Agency (JAEA). Emulsion Flow was originally developed to separate elements in spent nuclear fuel. In the course of research, we discovered a phenomenon that defied conventional wisdom: water and oil that mix perfectly and then separate perfectly. It was, in a sense, a miracle encountered in the realm of science. Captivated by this phenomenon, we decided to place our future in its potential.

Today, this technology is entering a new stage.

We are applying it to two major challenges: promoting resource circulation through lithium-ion battery (LIB) recycling, and removing environmental pollutants such as PFAS (per- and polyfluoroalkyl substances). Both are global issues, causing serious impacts around the world at this very moment. Emulsion Flow offers a groundbreaking solution that achieves highly efficient, low-cost, and selective separation and recovery—tasks that conventional technologies struggled to accomplish. We firmly believe this technology is a key to addressing these global challenges.

Since our founding, we have actively brought in experts in process development and plant design to accelerate technological development. At the same time, we have assembled diverse talent in management, business development, and global marketing, continuing to grow by advancing both “technology” and “business.” Currently, we are also actively expanding into overseas markets through partnerships with trading companies and utilization of various support programs. Through the dissemination of our technology, we aim to contribute to solving resource and environmental challenges worldwide.

We see in this advanced technology, born from nuclear research, a value that goes beyond mere “technology.” It represents our unwavering commitment to a sustainable society and our aspiration to create a future where no one is left behind.
