The dairy industry generates large volumes of whey as a byproduct cheese production, with high organic load. Its untreated discharge contaminates water bodies, reduces dissolved oxygen, and damages aquatic ecosystems. In Peru, especially in the rural areas Andes, thousands tons industrial waste are produced annually, representing an environmental economic challenge. lack sustainable technologies for its management drives need innovative solutions, such microbial fuel cells (MFCs), which combine treatment renewable energy generation. This research uses MFC technology substrate to observe potential generate electrical treat contaminants. Three liters from company Trujillo, were used stored at 10 °C. Each contained 800 mL employed activated carbon anode zinc cathode. A maximum voltage 0.867 ± 0.059 V was reached, current 4.114 0.239 mA recorded on 11th day. power density 1.585 0.061 mW/cm2, 4.448 A/cm2, internal resistance MFCs 16.847 0.911 Ω. initial pH approximately 3.0, increasing 4.135 0.264 day, conductivity increased 19.101 1.025 mS/cm first day 170.062 9.511 oxidation-reduction (ORP) 104.287 4.058 mV peak electricity generation (day 11). Additionally, 70% reduction chemical oxygen demand (COD) achieved, dropping 4650.52 10.54 mg/L 1400.64 23.25 last Metagenomic analysis identified two dominant bacterial phyla: Bacteroidota 48.47% Proteobacteria 29.83%. most abundant families Bacteroidaceae (38.58%) Acetobacteraceae (33.39%). study validates transform into resource, aligning sustainability circular economy goals, regions like Peru.

The treatment of agroindustrial wastewater using microbial fuel cells (MFCs) is a technological strategy to harness its chemical energy while simultaneously purifying the water. This manuscript investigates organic load effect as oxygen demand (COD) on production electricity during cassava by means dual-chamber cell in batch mode. Additionally, specific conditions were selected evaluate semi-continuous operational dynamics communities graphite anode also investigated. maximum power density delivered MFC (656.4 μW m

The release of anthraquinone dyes in aquatic sources has a huge impact on the environment because their turbidity, toxicity, mutagenicity, and carcinogenicity effects. Microbial Fuel Cell (MFC) is hopeful technology for decolorization dyes. goal present study Reactive Blue 4 (RB4) as an dye from aqueous solution by Baker's yeast MFC. selection three parameters (dye concentration, glucose airflow rate) optimization chemical oxygen demand (COD) removal are performed using response surface methodology (RSM). results demonstrated that interaction between does not affect efficiency, whereas concentration was found to be significant COD removal. Accordingly, optimum conditions maximum were obtained at 50 mgL−1, 1 gL−1, rate 10 mLmin−1.
