6th International Congress on Water, Waste and Energy Management (WWEM-22). 5th International Conference on Green Chemistry and Sustainable Engineering (GreenChem-22). 2022 International Conference on Green Energy and Environmental Technology (GEET-22).

This document is a special issue of the Environmental Science and Pollution Research Journal that focuses on three international conferences: the 6th International Congress on Water, Waste and Energy Management (WWEM-22), the 5th International Conference on Green Chemistry and Sustainable Engineering (GreenChem-22), and the 22nd International Conference on Green Energy and Environmental Technology (GEET-22). These conferences brought together researchers and scientists from around the world to discuss topics related to water, waste, green chemistry, green energy, and environmental technologies. The special issue specifically explores post-Covid trends and new insights for treating wastewaters and soils, including technologies for removing chemical and biological contamination. It includes selected papers from the conferences and acknowledges the organizers, authors, reviewers, and sponsors. The next edition of these conferences is scheduled for July 2024 in Lisbon, Portugal. Additionally, the document provides brief biographical information about several researchers in the field of chemical engineering and environmental science. It highlights their educational background, research interests, publications, and professional achievements. These researchers specialize in areas such as wastewater treatment, bioprocess technology, waste management, and catalysis. They have been involved in numerous research projects, published extensively, and received recognition for their work. The purpose of this document is to offer library patrons an overview of these researchers' qualifications and areas of expertise for potential research purposes. [Extracted from the article]
