Electrifying the UNSDGs with microbial power

Water stress represents a critical global challenge demanding innovative solutions for effective water resource management. Microbial electrochemical technologies (METs) leverage bacterial extracellular electron transfer for addressing issues related to water stress. These technologies exhibit a diverse range of applications, positioning them as integral to sustainable development through effective water resource management. Their versatility allows them to function as key contributors to achieving the United Nations Sustainable Development Goals (UNSDGs). Through their application, METs offer promising strategies for mitigating pollution, recovering valuable resources, and enabling real-time water quality monitoring. Employing these technologies facilitates the concurrent addressing of various UNSDGs, fostering a holistic and integrated approach. METs present opportunities for decentralized wastewater treatment and reuse, thereby promoting accessibility to clean water and sanitation, particularly in marginalized communities. However, the realization of these benefits faces significant challenges, including technological scalability, optimization, and regulatory frameworks. Overcoming these obstacles is crucial for harnessing the full potential of METs to meet UNSDGs. This perspective article underscores the imperative of further research, collaboration, and policy support to propel METs towards becoming a cornerstone in the sustainable management of water resources and the achievement of UNSDGs on a global scale.
