ST-29 [Trans-Division Symposium]
Frontiers of Chemical Engineering Approaches to Solving Increasingly Complex Environmental Issues

Organizers: Akamatsu Kazuki (Kogakuin Univ.), Terada Akihiko (TUAT), Suenaga Toshikazu (Hiroshima Univ.)

Chemical engineering approaches are a powerful tool to address various environmental issues related to water/air/soil, which should be also discussed from the viewpoint of the carbon neutral concept. This symposium welcomes presentations on innovative separation materials and systems for solving increasingly complex and serious environmental problems. Future directions and perspectives will be widely discussed. We look forward to the active participation of young researchers.
