A Report on Participation in the 22<sup>nd</sup> International Symposium on Wood, Fiber, and Pulping Chemistry（ISWFPC）2025, Raleigh

The ISWFPC is an important international symposium that encompasses researchers in the field of wood chemistry, chemistry of fibers related to wood components, and chemistry of pulping and bleaching, as it covers a wide range of topics from basic to applied chemistry. Since the first symposium was held in Stockholm, Sweden in 1981 as the “Ekman Days”, it has been held every other year except for 2021, when it was cancelled due to the pandemic. The name of the 2nd-12th symposia was “ISWPC” because pulping and bleaching chemistry and chemical structure of lignin were the main themes in the 20th century. Cellulose nanofibers and biorefineries have become important themes in the 21st century, resulting in changing the name to “ISWFPC from the 13th symposium. The 23rd and 24th ISWFPC will be held in Pekanbaru, Indonesia in 2027 and in Nanjing, China in 2029, respectively.
