“…Subsequently, Choi and Ahn 27 also reported that the MFC reactor produced 0.77 W/m 2 of power density with food waste leachate as substrate and 24 mL of working volume reactor. The research from Moharir and Tembhurkar 28 also showed relatively the same result, claiming that the MFC reactor produced 0.29 W/m 2 of power density. These results confirmed that the high power density produced in the MRC reactor is due to the salinity energy created from the small number of membrane pairs (RED stack).…”

In this study, the effect of external resistance on the microbial reverse-electrodialysis cell (MRC) performance using organic-rich wastewater as an electron donor was examined. The optimum of external resistance was determined to be 300 Ω. In such condition, the power density of 1.53 ± 0.198 W/m2, substrate removal of 52 ± 2.3%, Coulombic efficiency of 70 ± 2.6%, energy recovery of 3.0 ± 0.4%, and energy efficiency of 53 ± 7.1% were obtained in the MRC. The differences in power density at different external resistances were mainly due to the changes in internal resistance and ion flux efficiency in the MRC. The external resistance affected substrate removal and Coulombic efficiency through the length of batch cycle time, and current density exchanged as well as the Tafel slope. Furthermore, the proper external resistance applied to the reactor created high power production; thus, high energy efficiency and energy recovery were achieved. These results demonstrated that selecting proper external resistance was an essential key for a successful MRC operational.

“…Finally, the most characteristic peaks in the region 1500-500 cm −1 are 1067, 1006 and 634 cm −1 , and are associated with the stretching vibrations of starch and the anomeric region [40][41][42]. The decrease in the intensity of peaks is mainly due to the breaking of bonds in the process of degradation and generation of bioelectricity [43]. According to Kale et.…”

Papaya (Carica papaya) waste cause significant commercial and environmental damage, mainly due to the economic losses and foul odours they emit when decomposing. Therefore, this work provides an innovative way to generate electricity for the benefit of society and companies dedicated to the import and export of this fruit. Microbial fuel cells are a technology that allows electricity generation. These cells were produced with low-cost materials using zinc and copper electrodes; while a 150 mL polymethylmethacrylate tube was used as a substrate collection chamber (papaya waste). Maximum values of 0.736 ± 0.204 V and 5.57 ± 0.45 mA were generated, while pH values increased from 3.848 to 8.227 ± 0.35 and Brix decreased slowly from the first day. The maximum power density value was 878.38 mW/cm2 at a current density of 7.245 A/cm2 at a maximum voltage of 1072.77 mV. The bacteria were identified with an identity percentage of 99.32% for Achromobacter xylosoxidans species, 99.93% for Acinetobacter bereziniae, and 100.00% for Stenotrophomonas maltophilia. This research gives a new way for the use of papaya waste for bioelectricity generation.

“…As shown in table 3, the effects of recirculation bolstered the production of electricity as the yields were much higher than that of the typical batch method. The COD removal efficiency of the recirculating reactor was also higher than the typical batch reactor for all of the different OLRs (Moharir, et al, 2018). As recirculation promotes a higher mixing of components, as well as a more active waste source mirroring the effects of an increased temperature, it was concluded that the recirculation of waste is effective in increasing the output of the MFC.…”

Due to the exponential growth of the human population and declining environmental quality in the world, waste derived volatile fatty acids (VFAs) have been identified as a source for the production of value-added products. Throughout this paper, different technologies for the production of value-added products from VFAs, various high content VFA waste streams and value-added products from each process will be discussed. Additionally, an in-depth literature review will be conducted on 5 value added products from VFAs. Highlights of various experiments will be identified as well as common trends in experiments to date. Some considerations will also be given to particular strategies and methods which may enhance the production of a value-added product in the future. Even through the uncertainty it has been proven that waste derived VFAs are a major candidate in contributing to a more environmentally and sustainable society in the immediate future.
