ABSTRACT Biochar-assisted anaerobic digestion (AD) remains constrained due to the inefficient decomposition of complex organics, even with direct interspecies electron transfer (DIET) pathway. The coupling electrochemistry biological treatment could shorten lengthy retention time in co-digestion by improving rates and inducing functional microbial acclimation. Thus, this work investigated potential performance AD low-magnitude electric fields biochar derived from anaerobically digested biogas residue. Different voltages (0.3, 0.6, 0.9 V) were applied at various stages assess impact on biochar-assisted AD. results indicate that an external voltage 0.3 V, coupled 5 g/L biochar, elevates CH4 yield 45.5% compared residue alone, approach increased production up 143% within 10 days.

Abstract Waste activated sludge (WAS) is attracting attention for its energy and resource potential. Anaerobic digestion (AD) can be used to efficiently recover resources stabilize pollutants in WAS, with biochar emerging as an ideal additive boost this process. However, the low abundance of surface functional groups small pore structure raw may limit performance AD WAS. These limitations overcome by using biochar. In review, preparation modification methods role WAS are systematically summarized discussed. Notably, electron transfer, buffering effects, microbial immobilization, alleviation inhibitory modulation analyzed. Additionally, impacts on digestate utilization, pollutant removal, carbon fixation Special given ability promote circular economy neutrality. Finally, future perspectives use presented. The aim review provide insights into application from perspective improvement, economy. Graphical
