“…Sustainability 2023, 15, x FOR PEER REVIEW 8 of 13 of 0.180 W/cm 2 in their single-chamber MFCs using leachate as the substrate [58]. Likewise, the research carried out by Gautam et al ( 2021) managed to generate 2400 ± 110 W/cm 2 in their MFCs using sewage sludge, compost leachate, and mess food waste and graphite rod electrodes as the substrate [59]. The high values obtained in the investigation may be due to the electrodes used, which, due to their metallic characteristics, have a high electrical conductivity, facilitating the passage of electrons through the entire electrode area [60,61].…”

Pollution generated by the misuse of large amounts of fruit and vegetable waste has become a major environmental and social problem for developing countries due to the absence of specialized collection centers for this type of waste. This research aims to generate electricity in an eco-friendly way using red dragon fruit (pitahaya) waste as the fuel in single-chamber microbial fuel cells on a laboratory scale using zinc and copper electrodes. It was possible to generate voltage and current peaks of 0.46 ± 0.03 V and 2.86 ± 0.07 mA, respectively, with an optimum operating pH of 4.22 ± 0.09 and an electrical conductivity of 175.86 ± 4.72 mS/cm at 8 °Brix until the tenth day of monitoring. An internal resistance of 75.58 ± 5.89 Ω was also calculated with a maximum power density of 304.33 ± 16.51 mW/cm2 at a current density of 5.06 A/cm2, while the FTIR spectra showed a decrease in the initial compounds and endings, especially at the 3331 cm−1 peaks of the O–H bonds. Finally, the yeast-like fungus Geotrichum candidum was molecularly identified (99.59%). This research will provide great opportunities for the generation of renewable energy using biomass as fuel through electronic devices with great potential to generate electricity.

“…Over the past few years, integrated bio-electrochemical and hybrid oxidation systems have been investigated as an effective platform for the degradation and mineralization of various contaminants present in wastewater. 126 The main concern associated with the conventional wastewater treatment technologies such as activated sludge processes, trickling filters, sequencing batch reactor, traditional coagulation or flocculation processes, etc. is that they are energy intensive.…”

The microbial electrolysis cell is gaining advantage over the other biological hydrogen production techniques as it requires less energy for hydrogen generation as compared to the water electrolysis process. The present study aims to assess the aptness of Agro-Industry Waste (AIW) fed membrane-less single chambered Microbial Electrolysis Cell (SC-MEC) for the biohydrogen production in batch mode under applied voltage of 1 V at 30 ± 2 °C (Fig.1). The performance of the reactor was assessed through volume of hydrogen per gram of COD removed, columbic efficiency, cathodic hydrogen recovery and COD removal efficiency. The highest COD removal of 71% was reported with columbic efficiency of around 45%. These results demonstrated an energy-efficient approach for biohydrogen production from AIW coupled with waste mitigation.
