Emulsion Flow Technologies joined the Tokyo Metropolitan Government's SusHi Tech Global Growth Acceleration Program. The Japanese startup develops an emulsion flow technology that separates and concentrates PFAS compounds. The program offers up to 18 months of funding and tailored support.
European commercialization
EFT plans to receive wastewater samples from across Europe for feasibility studies and testing. It plans to build a local base with PFAS treatment, water treatment, and engineering partners. The company wants to create a repeatable commercial model rather than one-off demonstrations.
Technology profile
EFT's emulsion flow method originated at the Japan Atomic Energy Agency. In tests with real wastewater, it removed more than 99.9% of PFOS and PFOA and concentrated PFAS up to 2,400 times. The technology works alongside existing treatments such as activated carbon, ion exchange resin, and membrane separation.
Plans for Japan and beyond
After building its European base, EFT plans to bring commercial data and operating know-how back to Tokyo. It wants to apply the method to PFAS challenges in Tokyo groundwater and environmental water. The company also aims to expand to municipalities and industries across Japan, the US, and Asia.
EFT also lists rare earths, rare metals, and lithium-ion battery recycling as future applications. These areas are longer-term goals rather than current commercial work. The company says it aims to build a sustainable resource-circulation business.
