AB - Polytetrafluoroethylene (PTFE) is one of the most common binders employed to prepare cathode elec-trodes in microbial fuel cells (MFCs) and yet this fluorinated polymer is neither sustainable nor environ-mentally friendly. In this work, four non-fluorinated polymers have been tested as alternative binders to PTFE in ceramic MFCs. The performance of ceramic MFCs using carbon-based cathodes containing sili-cone, polyvinyl chloride, Ludox  (colloidal silica) and chitosan, was compared with the performance of MFCs using cathodes prepared with PTFE. The results obtained confirm that polyvinylchloride, Ludox  and chitosan are suitable materials to be used as binders for MFC cathode construction. Amongst them, Ludox  and chitosan are the most sustainable options due to their chemical structure. Cathodes prepared with 2.5 wt% of chitosan – 8 times less than the amount needed for PTFE – in MFCs reached a maximum power of 510 lW, which represents 60.3% out of the power output from MFCs with PTFE-based cathodes. In terms of urine treatment capacity, the chemical oxygen demand (COD) removal was equivalent across the systems tested, due to the short retention time. However, chitosan-based MFCs reached COD removal rates of up to 26%, which was slightly higher than the COD removal rate measured for MFCs using PTFE-cathodes (23.5%).
