The Eighth International Symposium on Environmental Biotechnology and Engineering is themed “Harnessing Microbial Potential to Address Critical Environmental Challenges.” As the world faces increasing pressures from climate change, pollution, and resource scarcity, this event gathers an international community of researchers and experts to explore innovative microbial solutions for these urgent issues. Discussions will center on the role of microbial processes in climate change adaptation and mitigation, the development of advanced biorefinery technologies, and more efficient approaches to resource recovery, including the production of value-added chemicals from waste streams. The symposium will explore strategies for the remediation and management of emerging contaminants. It will also address the complexities of sustainable wastewater treatment and reuse, focusing on the latest approaches. Additionally, insights into the application of molecular biology tools will be highlighted, along with their use in wastewater-based epidemiology. The event will emphasize the adoption of cleaner production methods in industry and the creation of environmental management strategies that can meet regional needs. By fostering interdisciplinary dialogue and global perspectives, the symposium aims to highlight the crucial role of microbes in advancing environmental technologies and shaping a sustainable future across diverse contexts.
