Dr Anil Kumar Patel is currently an Associate Professor at the Institute of Aquatic Science and Technology, National Kaohsiung University of Science and Technology, Kaohsiung, Taiwan. He is also Senior Scientist (Honorary) at the Centre for Energy and Environmental Sustainability – India. He obtained his MSc degree in Biotechnology from Guru Ghasidas University, Bilaspur, India and PhD in Biotechnology from the North Maharashtra University, Jalgaon, India. His broad post-doctoral research was carried out in several overseas labs basically on waste-to-wealth. The area of his current work is mainly environmental bioengineering, broadly focused on waste to fuel/non-fuel products program utilizing bacterial, and algal systems. Previously he worked at Research Professor at Department of Chemical and Biological Engineering, Korea University, Seoul and HKBU, Hong Kong on algal biorefinery project and solid waste management. He worked at University of Hawaii, USA on removal of sulfur from gaseous phase of treated S-containing wastewaters by applying designer-biochar which was used for sulfur nutrition in plants. He gained experience in biohythane production using ethanol plant wastes at DBT-IOC Bioenergy Centre, India, also on membrane bioreactor for continuous biohydrogen production as well as VFA separation from industrial waste at Institute Pascal, France. He has been a visiting researcher at EPFL, Switzerland to work on biomass pretreatments. In these studies, both bench-scale and pilot-scale studies were undertaken with techno-economic analysis. He has over 100 publications/communications, which include 04 patents, 80 original and review articles, 22 book chapters and 2 conference proceedings. Dr Reeta Rani Singhania is currently a Research Associate Professor at the Department of Sustainable Environment Research Center, National Kaohsiung University of Science and Technology (NKUST), Kaohsiung, Taiwan. She is also Senior Scientist (Honorary) at the Centre for Energy and Environmental Sustainability – India. She worked at CSIR-National Institute for Interdisciplinary Science and Technology, Trivandrum for PhD studies and obtained the degree in Biotechnology in 2011. During 2011-2012, she worked as post-doctoral fellow at University Blaise Pascal, Clermont-Ferrand, France and 2012-2017 at DBT-IOC Centre for Advanced Bioenergy Research, Faridabad as “DBT-Bioscience Energy Overseas Fellow”. Subsequently, she joined the Centre for Energy and Environmental Sustainability, India and worked as Chief Scientist during 2018-2020. Her major research interests are in Microbial & Enzyme Technology and Bioprocess Technology, with current focus on biofuels from lignocellulosic biomass. She has 16 patents, edited three books and published more than 120 research articles, book chapters and conference communications with more than 7100 citations and h index of 32 (Google scholar). Dr. Cheng-Di Dong is a Distinguished Professor at the Department of Marine Environmental Engineering at National Kaohsiung University of Science and Technology (NKUST). He is also the Dean of College of Hydrosphere Science and the Director of Sustainable Environment Research Center (SERC) of NKUST. He earned a Ph.D. degree in Environmental Engineer from University of Delaware in 1993. His current research interests are broadly clustered in the areas of monitoring and remediation of contaminated water, soil and sediments. He is particularly interested in developing fate and transport of contaminants in marine sediments, and remediation of contaminated sediments for the purpose of reuse sediment materials using physical, chemical and biological processes. Prof. Dong has participated in the scientific committee of several conferences and associations and serves as a reviewer in a wide range of international renowned journals. He has published more than 291 papers in leading international journals, 8 patents, 5 book chapters, and edited 8 special issues of scientific journals.
