“…The same goes with the current, it is higher than the cells stacked in series, and it generates stable current as the stacking of cells increases (starting in cell 3 through cell 6). From the studies of other bioelectrochemical systems like MFCs, serially stacked MFC systems or units could provide a higher voltage (Selvasembian et al, 2021;He et al, 2017). Still, it has often been proven to be difficult and ineffective due to the voltage reversal or the reverse polarity, which results in the fuel shortage of the individual units and leads to significant overall voltage decay (Molognoni et al 2021).…”

The prevalence of non-renewable energy has always been a problem for the environment that needs a long-term solution. Plant-Microbial Fuel Cells (PMFCs) are promising bioelectrochemical systems that can utilize plant rhizodeposition to generate clean electricity on-site, without harming the plants, paving the way for simultaneous agriculture and power generation. However, one of the biggest hurdles in large-scale PMFC application is the diffused nature of power generation without a clear path to consolidate or amplify the small power of individual cells. In this study, stacking configurations of 3D-printed PMFCs are investigated to determine the amplification potential of bioelectricity. The PMFCs designed in this study are made of 3D-printed electrodes, printed from 1.75 mm Proto-pasta (ProtoPlant, USA) conductive PLA filament, and a terracotta membrane acting as the separator. Six cells were constructed with the electrodes designed to tightly fit with the ceramic separator when assembled. An agriculturally important plant (S. Melongena) was utilized as the model plant for testing purposes. Stacking of cells in series had resulted in severe voltage loss while stacking of cells in parallel preserved the voltage and current of the cells. Cumulative stacking verified the increasing voltage losses as more cells are connected in series, while voltage and current were generally supported well as more cells were connected in parallel. Combination stacks were also investigated, but while 2 sets of 3 cells in parallel stacked in series generated proportionately larger power and power density compared to individual cells, the drop in current density suggests that pure parallel stacks are still more attractive for scaling up, at least for the proposed stake design in this study. The results of this study indicated that the scale up of PMFC technology is possible in field applications to continuously generate electricity while growing edible plants.

“…However, there are a few challenges that are impeding progress toward the commercialization of these technologies. Still, many unanswered questions remain regarding the implementation of METs at a pilot or field scale for industrial wastewater treatment, such as the cost of installation and operations, energy requirements, and efficacy [8]. The operation of METs is beneficial in the short term; however, research should be directed toward determining their long-term suitability for the generation of valuables from waste.…”

“…In addition, due to a lack of proper rules and regulations, a considerable quantity of effluent is discharged into the environment without providing the required treatment, which can further result in adverse environmental impacts such as eutrophication, massive depletion of oxygen, etc. Therefore, dairy wastewater requires appropriate treatment before being disposed into the environment [8,9]. Further, if strategies such as zero-liquid discharge and reuse of treated water are implemented in the dairy industry, it would go a long way toward dealing with the issues associated with water pollution from this industrial sector [10,11].…”

Dairy Wastewater as a Potential Feedstock for Valuable Production with Concurrent Wastewater Treatment through Microbial Electrochemical Technologies

A milk-processing plant was drafted as a distinctive staple industry amid the diverse field of industries. Dairy products such as yogurt, cheese, milk powder, etc., consume a huge amount of water not only for product processing, but also for sanitary purposes and for washing dairy-based industrial gear. Henceforth, the wastewater released after the above-mentioned operations comprises a greater concentration of nutrients, chemical oxygen demand, biochemical oxygen demand, total suspended solids, and organic and inorganic contents that can pose severe ecological issues if not managed effectively. The well-known processes such as coagulation–flocculation, membrane technologies, electrocoagulation, and other biological processes such as use of a sequencing batch reactor, upflow sludge anaerobic blanket reactor, etc., that are exploited for the treatment of dairy effluent are extremely energy-exhaustive and acquire huge costs in terms of fabrication and maintenance. In addition, these processes are not competent in totally removing various contaminants that exist in dairy effluent. Accordingly, to decrease the energy need, microbial electrochemical technologies (METs) can be effectively employed, thereby also compensating the purification charges by converting the chemical energy present in impurities into bioelectricity and value-added products. Based on this, the current review article illuminates the application of diverse METs as a suitable substitute for traditional technology for treating dairy wastewater. Additionally, several hindrances on the way to real-world application and techno-economic assessment of revolutionary METs are also deliberated.
