In the face of escalating challenge sludge production and disposal in wastewater treatment plants (WWTPs), situ reduction biotechnology (ISRB) has recently emerged as a highly promising strategy. It not only potential to curtail generation at its origin but also ensures sustained efficiency process. Several key strategies have demonstrated exceptional harnessing microbial processes for degradation. They encompass enzymatic hydrolysis, inoculation, protozoan/metazoan predation, bacteriophage lysis, biofilm-based manipulation. Compared traditional methods (e.g., incineration landfilling), these biotechnologies offer significant advantages through lower costs, reduced energy consumption, minimal environmental impacts. The efficacy ISRB is substantially affected by various factors, where pH, shift, nutrient conditions play crucial roles. Despite notable progress made this field, challenges persist when it comes scaling up technologies more extensive widespread applications. This review comprehensively highlights fundamental mechanisms, application strategies, future prospects ISRB, including one first studies introduce bacteriophage-based approaches reduction, offering novel perspective on phage-mediated control. By doing so, aims in-depth insights into role sustainable solution management, paving way further research development area biotechnology.
