Sustainable management of organic waste, such as food waste (FW) and livestock manure (LS), is essential for reducing pollution promoting resource recycling. This study investigated the effects Bacillus sp. inoculation biochar addition on composting efficiency, microbial dynamics, physicochemical properties. accelerated breakdown cellulose lignin, reduced moisture content, stabilized pH, mitigated ammonia volatilization. Biochar emissions by 17.04%, increasing to 28.89% with Next-generation sequencing revealed enhanced diversity, suppressed pathogens, promoted beneficial interactions. LS treatments retained Firmicutes dominance (up 95.17%), improving nitrogen retention, while FW transitioned Proteobacteria Bacteroidota, driving plant material decomposition. By day 35, increased late-stage taxa (Deinococcota, Myxococcota), linked degradation pathogen suppression. In compost (FWBC), Planococcaceae Bacillaceae synergistically decomposed complex matter. (LSBC) anaerobic families like Clostridiaceae Peptostreptococcaceae, lowering methane hydrogen sulfide emissions. Microbial network analysis highlighted improved cooperation under sp., LSBC sustaining positive interactions at higher dosages. These results demonstrate that inoculants enhance nutrient cycling, environmental sustainability.
