The ICEST 2025 is the 16th Annual Conference in this series of scientific events to advancing research and innovation in environmental science and technology. It is designed for scholars and scientists in environmental science, engineers, consultants, and practitioners working on environmental solutions and decision-makers shaping environmental policies and regulations, etc.
The proceedings features cutting-edge research and advancements in environmental science, sustainability, and technology. Covering topics such as climate change, pollution control, renewable energy, and ecological conservation, the proceedings includes peer-reviewed papers from leading researchers, practitioners, and policymakers worldwide. This book serves as a valuable resource for addressing global environmental challenges and promoting innovative solutions for a sustainable future.
Dr. Yongping Li receives her M.Sc. and Ph.D. degrees from the University of Regina, Canada. Currently, she is Changjiang Scholar Professor at Beijing Normal University, China. Her research interests involve in energy and environmental systems analysis, environmental pollution control, water resources management, and decision-making under uncertainty. Dr. Li has led or involved in over 60 energy- and environment-related research projects supported by industrial, governmental, and international organizations. She has produced over 450 peer-refereed international journal papers (SCI-based H-index of 58) and supervised over 90 master/Ph.D. students. She has been continuously selected as Highly Cited Scholar in the field of “Environmental Science” (by Elsevier) since 2013. She has been continuously included in Stanford University’s 2020-2023 World Ranking for the world’s top 2 percent of most-cited scientists in the field of Environmental Engineering.
Dr. Yang ZENG is Professor and Doctoral Supervisor at the School of Environmental Science and Engineering, Shandong University. He holds dual master’s degrees from AgroParisTech and Tongji University and received his Ph.D. in chemistry from the University of Rennes 1, in collaboration with the INRAE. With over 20 years of research experience, Dr. Zeng’s work focuses sustainable waste valorization, and nitrogen pollution control, with particular expertise in the source apportionment and mitigation of reactive nitrogen species (e.g., NH3, HONO, and NOx) from waste management and agricultural systems. He is Recipient of the NSFC Research Fund for International Excellent Young Scientists (RFIS-II) and serves on the Youth Editorial Board of Environmental Sanitation Engineering.
