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
