Professor Sheng-Jie You earned his Ph.D. from the Graduate Institute of Environmental Engineering at National Central University, Taiwan, in 2001. After completing his military service in the Air Force, he joined the Department of Civil Engineering at Chung Yuan Christian University (CYCU) in 2003. In 2004, he founded the Department of Bioenvironmental Engineering, which was later renamed the Department of Environmental Engineering in 2015. Professor You's research focuses on membrane and photocatalytic applications in water and wastewater treatment, air pollution control, groundwater remediation, and resource recovery from waste. He has authored over 300 journal papers, conference papers, and reports, and has advised more than 100 Ph.D. and master's degree students over the past 20 years. Professor You has received numerous awards, including the Outstanding Research Professor Award and the Excellent Contribution to Industry-Academia Cooperation Award from CYCU, as well as several Best Paper Awards at various conferences.

Circular Society Laboratory (https://wxy.cycu.edu.tw/) 

In 2004, Professor Sheng-Jie You and Professor Ya-Fen Wang established the Membrane Research Lab and the Plasma Research Lab, focusing on wastewater and air pollution control, respectively. As the research evolved to encompass cross-disciplinary approaches, the two labs were integrated into the Circular Society Lab in 2014. Dr. David Tsai has worked as a postdoctoral researcher in the Circular Society Lab since 2014. Professor Tien-Chin Chang joined the Circular Society Lab in 2023.

In 2024, the Circular Society Lab has 41 members, including 3 professors—Professor Sheng-Jie You, Professor Ya-Feng Wang, and Professor Tien-Chin Chang, 1 Postdoctoral fellow, Dr. David Tsai, 7 research staff, 14 Ph.D. students, and 16 Master's students. In our lab, international students comprise 56% from Indonesia, 27% from Vietnam, 5% from the Philippines, 5% from Mongolia, 3% from Pakistan, 2% from Haiti, and 2% from Peru.

Regarding research, we focus on membrane, plasma, and photocatalytic research in various environmental issues. In the past, environmental engineering was separated into several divisions, such as wastewater/water, air pollution, solid/liquid waste, groundwater, and noise, based on the issue of the problem. Nowadays, the Circular Society Lab applies integrated techniques to solve environmental problems. We develop novel photocatalysts and apply membrane technology for pollutant treatment (Membrane Bioreactor or membrane reactor) and also develop several technologies (Foulant Reducer, Photocatalytic Membrane) to solve advanced problems. We also apply membrane technology for the recovery of rare elements from solid waste (Supported Liquid Membrane), for biogas or syngas separation (Gas Separation Membrane), and for hazardous/valuable elements concentrated from liquid or to obtain high-quality water rather than the RO process (Membrane Distillation). Plasma technology is also applied to treat hazardous solid waste or waste liquid or agricultural waste, not only to minimize the waste volume but also to produce valuable products, even to modify the membrane surface for grafting chemicals onto it.

We focus on the integration of techniques and strive to provide a total solution to environmental issues. Therefore, constructing the Circular Society based on techniques is our future goal.
