Confirmed degradation of per- and polyfluoroalkyl substances (PFAS) in real-world water through joint research with Niihama National Institute of Technology

Joint research with National Institute of Technology, Niihama College confirmed that PFAS decomposition by an iron oxide photocatalyst proceeds even in water from real-world environments, such as rivers and dams. The company plans to continue validation aimed at optimizing treatment conditions and scaling up the technology.
