Sludge-derived biochar (SDB) synthesized by the pyrolysis of sludge is gaining enormous interest as a sustainable solution to wastewater treatment and disposal. Despite proliferation general reviews, focused synthesis on SDB-specific advances, particularly covering recent surge in multifunctional applications (2020–2025), receives little emphasis. In particular, critical analysis trends, application challenges, future research directions for SDB still limited. Unlike broader this mini-review highlights comparative advantages limitations SDB, identifies emerging integration strategies (e.g., bio-electrochemical systems, catalytic membranes), outlines priorities toward enhancing durability environmental safety applications. Specifically, review summarized advances from 2020 2025, focusing exclusively functional modifications, practical across diverse technologies involved adsorption, oxidation, membrane integration, electrochemical processes bio-treatment systems. Quantitative comparisons adsorption capacities >99% Cd2+ removal, >150 mg/g tetracycline adsorption) degradation efficiencies are provided illustrate improvements. The potential evaluating traditional contaminant among Fenton-like, persulfate, peracetic acid activation systems was emphasized. Integration with reduces fouling, while applications, including microbial fuel cells, yield higher power densities. To improve functionality SDB-based targeting contamination modification strategies, i.e., thermal activation, heteroatom doping (N, S, P), metal loading, played crucial roles. Emerging trends highlight hybrid persistent free radicals non-radical pathways. progress, challenges persist scalability, long-term stability, lifecycle assessments, scale-up implementation. targeted offers valuable insights guide development deployment management.
