Sustainable recycling of carbon resources from waste-activated sludge (WAS) is essential for advancing the circular wastewater economy. Anaerobic fermentation provides an eco-efficient pathway converting organic matter into volatile fatty acids (VFAs). In this study, Fe-N modified biochar was innovatively prepared WAS acetic acid yield enhancement, and system realized closure material cycle. Results show that adding Fe-N-modified (made under conditions 0.2M FeCl3 10 g/L urea) led to a 38.8% increase in (1745 mg/L) 5.7% its percentage (60.5%) compared control. It also improved hydrolysis hydrolase activity. addition, increased relative abundance Chloroflexi, Actinobacteria, Bacteroidetes, among which Chloroflexi electro-active microorganism promotes transformation propionic butyric acid, while Bacteroidetes primary responsible VFA production. summary, may serve as effective promoting production during anaerobic WAS.

Microbial electrosynthesis (MES) cell use is an innovative approach for single-cell proteins (SCP) production. Coupling MES with the valorization of CO2 from anaerobic digestion and nitrogen livestock effluents has beneficial environmental effects, reducing greenhouse gas emissions overloading. In addition, power needed can come surplus renewable energy. this study, a biochar-functionalized cathode was tested at varying polarizations, i.e. non polarized, -0.6 V -1.0 vs Ag/AgCl, biogas-derived recovered ammonia pig slurry supplied. Negative polarization switched microbial community heterotrophic, typical unpolarized MES, to mix both heterotrophic autotrophic/electrotrophic communities mainly V. The more negative allowed highest N capture, 39 ± 2 % supplied CO2, 6.7 0.8 N. biomass characterization indicated protein content on dry matter basis 33.1 1.3 (unpolarized), 43.2 0.6 (-0.6 V) 69.1 1.0 (-1.0 V). amino acids profiles investigated showed high nutritional value produced biomass, not far those conventional sources used producing feed/food.
