Prof. Galal A. M. Nawwar completed his Ph.D. in 1983. In 1995, he became a professor of organic chemistry at the National Research Centre in Cairo, Egypt. He has served as the president of both the Chemical Industry institute and the Green Chemistry Department. His research program aims to synthesize biologically active small molecules and develop cost-effective discoveries utilizing waste to produce value-added products via zero-waste processes. Nawwar has published around 120 papers and holds 17 patents. He has supervised 25 PhD and master’s theses. He has conducted postdoctoral research at the University of Vienna, Austria; Odense, Denmark; and Regensburg, Germany. In his career, he had different evolutions agreements with multinational giant firms such as BASF, Merck, and DOW. He was awarded a golden medal at Geneva, Switzerland, innovations exhibition in 2018 and the World Intellectual Property organization Medal (2017 WIPO), these besides some local and regional awards.Hoda Sabry Othman is a researcher at the Green Chemistry Department of the National Research Centre in Egypt. She earned her PhD in 2020 from Ain Shams University, Egypt. Othman has authored many scientific articles and participated in several research projects. Her main research interest focuses on valorizing waste via eco-friendly recycling procedures to produce low-cost green additives, which can serve as alternatives to those from petrochemical sources in a wide spectrum of industrial applications.
