Niches for bioelectrochemical systems on the recovery of water, carbon and nitrogen in wastewater treatment plants

Climate change and future depletion of resources are two of the most important environmental challenges that humankind have ever faced. This mini-review aims to give a second chance to contaminated water and recalcitrant carbon dioxide (CO2) streams by putting forward a resilience and sustainable technology based on electron-driven microbial reactions. A critical assessment of the current application of microbial electrochemical technologies (METs) in the field of electro bioremediation of contaminated water and bio-electro CO2 recycling in wastewater treatment plants (WWTPs) is performed. Data from lab-scale and pilot-plant studies is shown to prove that MET is a highly promising and cost-effective technology for the sustainable remediation of contaminated sites while producing biofuels and/or commodity chemicals from recalcitrant CO2 streams emitted in WWTPs.
