Dr. Meththika Vithanage is a Professor in the Department of Geochemistry at the Geological Survey of Denmark and Greenland, Denmark. Her work centers on quantifying concentrations and reaction kinetics of key and emerging pollutants, including microplastics, and Persistent, Mobile and Toxic contaminants. She advances understanding of their environmental fate and transport and develops remediation strategies using innovative geo-, bio-, and nanomaterials.Dr. Rohan S. Dassanayake is a Professor of Biophysical Chemistry in the Department of Biosystems Technology at the University of Sri Jayewardenepura, Sri Lanka. His research focuses on the development and characterization of advanced biomaterials and their derivatives to address global challenges related to industrial dyes, carbon emissions, packaging, and biomedical applications. He specializes in intelligent bioplastics, particularly for food packaging, as well as nanocomposites for dye removal and carbon dioxide (CO2) capture. Additionally, his work includes the fabrication of biosensors for ocular pH detection, targeted drug delivery, wound dressing, and wearable electronic devices.Mika Sillanpää is a professor at the University of Johannesburg, South Africa. His research centers on chemical treatment in environmental engineering, environmental monitoring, and resource recovery from waste streams.Sillanpää received his M.Sc. (Eng.) and D.Sc. (Eng.) degrees from the Aalto University where he also completed an MBA degree in 2013. Since 2000, he has been a full professor/adjunct professor at the University of Oulu, the University of Eastern Finland, the LUT University, the University of Eastern Finland and the University of Johannesburg.He has received numerous awards for research and innovation. He is the first Laureate of Scientific Committee on the Problems of the Environment (SCOPE)’s Young Investigator Award, which was delivered at the UNESCO Conference in Shanghai 2010 for his “significant contributions, outstanding achievements and research leadership in Environmental Technological Innovations to address present water pollution problems worldwide, especially with regard to wastewater treatment and reuse. In 2011, he was invited to act as a Principal Scientific Reviewer in the GEO-5 report of the United Nations Environmental Programme (UNEP). In 2012, he received Tapani Järvinen Environmental Technology Award and Publication Award of the Lappeenranta University of Technology. In 2014, he received the Science Award of the Lappeenranta University of Technology and Pro Mikkeli Award. In 2018, he was invited as a Member of the Finnish Academy of Sciences and Letters and Technology Academy of Finland. He also received Literature award from the Water Association of Finland in 2018.
