The recovery of polluted sites is an urgent need to be addressed and the development of innovative remediation technologies, which exploit nature based solutions, is strongly encouraged, in line with the new EU Circular Economy Action Plan. Terrestrial microbial fuel cells TMFCs can be a valuable tool for recovering soils polluted by various organic and inorganic contaminants. TMFCs benefit from capabilities of microbial biofilms developed on the electrodes, which use the terminals as catalysts for metabolic activities, including contaminant degradation. This process produces energy, thanks to conversion of chemical bond energy stored in the bonds of organic compounds into electrical ones. This work describes construction materials, remediation capabilities and technology of the TMFCs, reporting the last advances in TMFCs such as soil based reactors or in combination with plants plant microbial fuel cell PMFC . Some aspects related to microbiological activities for pollutant biodegradation, plant microbial interactions, energy production, and fields of application will be shown. Finally, abiotic factors which can improve bioremediation activities are also considered. Furthermore, limitations and issues for large scale applications, as well as for stacking and scaling up are discussed.
