Heavy metal contamination of soil and water is an escalating global environmental issue driven by industrialization and poor waste management. This problem is no longer confined to urban areas, as even small towns are grappling with severe heavy metal contamination, posing substantial threats to human health and aquatic ecosystems. To address these issues, fungal fuel cells have become one of the most promising and environmental friendly technologies. This technology is at the forefront of efforts to combat heavy metal contamination. This method utilizes the unique properties of fungi at the biocathode to treat contaminants and remove heavy metals from soil and water. In addition to reducing pollution, this technology has the capacity to generate electrical current which can serve as an alternative to conventional remediation methods. This review aims to provide a general overview of the fungal fuel cells as a method of bioremediation to remove toxic heavy metals and while simultaneously generating electricity. This review is based on a critical analysis of the recent peer-reviewed publications focusing on the development, operation, and application of fungal fuel cells in heavy metal remediation and bioelectricity production. By exploring the potential of fungal fuel cells, the review provides insight into a future where heavy metal pollution is effectively curtailed while contributing to sustainable energy production, thereby fostering a cleaner and healthier environment.
