Abstract

Abstract Promoting the transition toward a circular economy and sustainable development through scientific and technological innovation is the only viable strategy for leading to energy‐saving solutions, waste valorization, and efficient integration of renewable resources. Thanks to its dual function of harvesting energy from waste and cleaning up waste from organic pollutants, microbial fuel cells (MFCs) can be considered as a revolutionary tool for addressing the global environmental challenges. Here, several aspects of MFC technology are considered: basic principles and operational conditions, the role of materials efficiency for enhancing MFC performance, bacterial extracellular electron transfer mechanisms, the effect of different substrates used, and perspectives for technology scaling up. Special emphasis will be given to the development of low‐cost and effective catalysts for oxygen reduction reaction at the cathode side, as a key aspect for reducing the high cost of current electrode materials which limits the implementation of larger‐scale MFC systems. The application of MFCs in environmental monitoring and bioremediation is also reviewed, highlighting still existing limitations and potential future research for promoting the combination of MFCs with well‐established technologies.
