“…Radeef A. and Ismail Z. (2021) used waste from the potato chip processing industry as a substrate in their MFCs, observing a PD max of 434.8 mW/m 2 in the CD of 1165.6 mA/m, mentioning that the distance between the electrodes interferes with the results of the PD, as well as the size and material of each electrode used in the MFC [38]. The use of metallic electrodes facilitates the passage of electrons through the electrode area and between the chambers (anodic and cathodic) due to the high inherent electrical conductivity of the material [39], which explains the high power density values observed in this investigation.…”

The growing demand for agricultural products has increased exponentially, causing their waste to increase and become a problem for society. Searching for sustainable solutions for organic waste management is increasingly urgent. This research focuses on considering the waste of an Andean tuber, such as Olluco, as a fuel source for generating electricity and becoming a potential sustainable energy source for companies dedicated to this area. This research used Olluco waste as fuel in single-chamber microbial fuel cells using carbon and zinc electrodes. An electric current and electric potential of 6.4 ± 0.4 mA and 0.99 ± 0.09 V were generated, operating with an electrical conductivity of 142.3 ± 6.1 mS/cm and a pH of 7.1 ± 0.2. It was possible to obtain a 94% decrease in COD and an internal resistance of 24.9 ± 2.8 Ω. The power density found was 373.8 ± 28.8 mW/cm2 and the current density was 4.96 A/cm2. On day 14, the cells were connected in earnest, achieving a power of 2.92 V and generating enough current to light an LED light bulb, thus demonstrating the potential that Olluco waste has to be used as fuel in microbial fuel cells.

“…Te results showed that COD of potato wastewater was 84 mg/L while 67 mg/L was reported after COD removal which means there is 80% COD removal. Te observed decrease in COD could be attributed to the fact that the acetic acid was favorable to the bacterial species on the anode [32]. Additionally, in the assembly, the substrate degradation rate is higher due to the active oxidation of acetic acid substrate by microbes present in MFC.…”

Microbial fuel cells (MFCs), a technology that converts chemical energy into electrical energy, have been regarded as the most suitable method for sustainable energy production. However, most MFCs generate a low power output, limiting their large-scale industrial applications. Here, we introduce a high-performancesingle-chambered microbial fuel cell (SCMFC) based on carbon fiber anode and zinc oxide nanoparticle (ZnO NP)-fabricated copper cathode. Furthermore, best optimized conditions of temperature, pH, substrate, external resistance, and cathode fabrication were also considered to evaluate the performance of this SCMFC in treating potato wastewater along with bioenergy production. Results indicated that chemical oxygen demand (COD) could be effectively removed (80%) and maximum voltage, current density, and power density were 1.58 V, 0.235 mA/cm2, and 0.3714 mW/cm2, respectively. Hence, the SCMFC used in this study has a higher potential to treat potato wastewater along with high power production.

“…Afterwards, as leachates were recirculated, hydraulic loading was increased accordingly providing additional nutrients and sufficient moisture to accelerate the rates of biodegradation [25]. Moreover, food waste is a component that degrades quickly [26]. Because there were not enough microbes to completely break down all the soluble organic waste, the concentration of COD was likely higher [27].…”

The aim of the current study is to determine the impacts of leachate recirculation on the degradation of three compositions of municipal solid waste in anaerobic bioreactors. The study was completed by using six columns with equal volume (0.042m3) containing different densities and compositions of solid waste, in order to follow waste degradation over a limited time. Three compositions of waste were studied: simulated fresh waste of standard composition, simulated fresh waste of fermentable composition, and actual aged waste. Measurements of the significant parameters including pH, leachate conductivity, Chemical Oxygen Demand (COD), and waste settlement, were carried out. The quantity of oxidized organic matter was increased by the leachate recirculation, and the degradation period was reduced by using leachate recirculation. After 300, 150, and 480 days, waste stabilization seemed to be reached for fresh, aged, and fermentable waste, whereas the organic content decreased to 650, 480, and 4000mg COD/L, respectively.
