As research continues to elucidate the complex interactions between microorganisms, electrodes, and sediments, sediment microbial fuel cells (MFCs) or SMFCs are poised to play a critical role in environmental remediation and bioelectricity production. SMFCs offer a novel approach to harnessing the bio-electrochemical potential of microorganisms in a unique ecosystem. This review highlights the importance of electroactive bacteria (EAB) and their role in providing a sustainable and renewable energy from sediments. These independent units can offer significant opportunities in environmental remediation and bioelectricity production. Different configurations of SMFCs such as plant-MFCs and constructed wetland (CW)-MFCs are also discussed with their performance parameters and indicators. Recent advances in material design and operation have improved their efficiency, scalability, and cost-effectiveness, paving the way for their deployment in a range of applications, from monitoring water quality to powering remote sensors and devices. Additionally, the mathematical models used in bioremediation and bioelectricity production from electroactive microbes are also discussed. These models act as a roadmap to improve working potential of SMFCs with emphasis on electrode materials for both anode and the cathode. SMFCs enhance biogeochemical cycling, stimulate denitrification, and promote the degradation of pollutants, acting as a potent tool for ecosystem restoration. © 2025 Informa UK Limited, trading as Taylor & Francis Group.
Innovative approaches for carbon capture and storage as crucial measures for emission reduction within industrial sectors

Carbon capture and storage represented as CCS, is a technique that can be used to cut down on emissions of CO2 from industrial sources. These mechanisms can balance the excess fossil fuel usage and lead to effective carbon capture from the atmosphere and storing it in safe spaces. This can negate global warming and send the carbon back to geological spaces inside the earth. This review covers the operational mechanism of such technologies from its inception to the material innovation along with the transport of CO2 and its storage options. Breakthroughs in recent years have made it possible to design effective carbon capture and safe spaces for its storage. A comprehensive worldwide case studies are presented for both successful CCS project implementation and their environmental impact assessment. Lessons learned from these case examples are reflected through the challenges and policy hurdles with its impact on the global economy. An outlook is provided for the role of CCS in net zero emissions, renewables integration and advancing CCS research. By leveraging innovation across capture, utilization, and storage stages, CCS holds immense potential to play a transformative role in combating climate change and achieving global sustainability goals. © 2024 The Author(s)
Overcoming water, sanitation, and hygiene challenges in critical regions of the global community
(KeAi Communications Co., 2024) Debajyoti Bose; Riya Bhattacharya; Tanveen Kaur; Ritesh Banerjee; Tanya Bhatia; Aritra Ray; Bhavika Batra; Arnab Mondal; Paulami Ghosh; Surajit Mondal
This review provides a critical analysis of the global water and sanitation crisis, as well as how community-based approaches have led to innovative water management solutions. Regions of sub-Saharan Africa, south Asia, the Middle East, and island countries have been taken as models to understand mitigating crises related to water, sanitation, and hygiene (WASH) services. Selected WASH cases based on specific inclusion and exclusion criteria that highlighted finance, sustainability, and community engagement. The review analyses methods through which communities below the poverty line, living in densely populated areas, war zones, and island countries can foster innovation, and collaborations. © 2024
