Waste Biorefinery Technologies for Sustainable Development

Dr. Ponnusami is at present working as Associate Dean in the School of Chemical and Biotechnology, SASTRA Deemed University, India. He did the doctoral research on textile effluent treatment at SASTRA Deemed University, India. His post-doctoral research includes wastewater treatment by physico-chemical treatments, lignocellulose degradation, bioprocessing for the production of enzymes and microbial polysaccharides, and biodiesel production. Towards achieving the goals of sustainable development his team is exploring the uses of green methods in biorefining of biomass. In particular, bioconversion of biomass into microbial exopolysaccharides such as levan, xantham gum, dextran, cellulose that are suitable for food and medical treatments are investigated. As far as renewable fuels are concerned we mainly work on process development for biodiesel and bioethanol from various agricultural and industrial waste products. The group is interested in developing chemical and biocatalysts for above-mentioned conversion processes. Prof. Ponnusami is included in the list of top 2% highly cited researchers’ published by Elsevier, consecutively for the past two years (2021 and 2022). Prof. Xu is currently Chair Professor of Advanced Biorefinery and Director of Advanced Biorefinery Laboratory (ABL) at School of Energy and Environment, City University of Hong Kong. He is a Fellow of Canadian Academy of Engineering (FCAE) and Fellow of Engineering Institute of Canada (FEIC). He was a professor, the NSERC/FPInnovations Industrial Research Chair in Forest Biorefinery, and Associate Director of the Institute for Chemicals and Fuels from Alternative Resources (ICFAR) at Western University. He has over 20 years of research experience in conversion of biomass and organic solid wastes (forestry/agricultural residues, food wastes, wastewater sludge, microalgae, lignin, glycerol and sugars, etc.) into biofuels (sustainable aviation fuels, green hydrogen) and green chemicals and biopolymer materials. He has authored/edited 3 books on biorefinery, and published 20+ book chapters and 370+ papers in peer-reviewed journals. According to Google Scholar, his work has received nearly 25,000 total citations with an H-index of 82 to date. With 12 PCT/US/Canadian/Chinese Patents issued, Dr. Xu has made outstanding contributions to applied science and engineering practice. He is the recipient of the 2011 Syncrude Canada Innovation Award and the 2019 Award in Design and Industrial Practice from Canadian Society of Chemical Engineering, and the 2023 Humboldt Research Award from the Alexander von Humboldt Foundation. Dr. Saravanan Ramiah Shanmugam is currently working as Assistant Research Professor in Biosystems Engineering Department at Auburn University, Alabama, USA. He has previously worked as a DST Inspire Faculty in the School of Chemical and Biotechnology, SASTRA Deemed University, India. His primary research interests focus on the creation value from wastes. He received his Doctor of Philosophy degree from University of Windsor, Ontario, Canada. He has worked as an Associate Scientist in AgraCity Crop & Nutrition Ltd., Wallaceburg, Ontario, Canada.
