Animal carcass wastewater treatment and bioelectricity generation in up-flow tubular microbial fuel cells: Effects of HRT and non-precious metallic catalyst

- This study is the first attempt to test the feasibility of bioelectricity generation from ACW.
- MFC could harvest power from ACW simultaneously accomplish wastewater treatment.
- MnO2 could serve as an alternative of catalysts for ORR in an air-cathode MFC.
- The effects of MnO2 loading and HRT on MFCs performance were investigated.
