On behalf of the Organizing Committee and Advisory Committee, we sincerely welcome you to participate in the Supergreen 2022, the 12th International Conference on Supercritical Fluids organized by Asian Society of Supercritical Fluids (ASSF), Taiwan Supercritical Fluid Association (TSCFA) and National Taipei University of Technology (Taipei Tech). Considering the uncertain border security policy in Taiwan, Supergreen 2022 will be held in a hybrid mode.

All submitted and accepted oral presentations will be shown in an asynchronous webinar during the period from October 24 to October 27. The pre-recorded video will be collected in this asynchronous platform for Q&A. On the other hand, for the plenary and invited lectures, an on-site meeting at Gis Taipei Tech convention center will be held during the period from October 28 to October 29, and line streamed for the participants who can’t attend this on-site meeting. In addition, a poster session will also be held at Gis Taipei Tech convention center at October 28 for the presenting authors who can attend Supergreen 2022 on-site.
