Composting was an effective technique to treat kitchen waste into high-quality fertilizer or soil amendment. The unsynchronized conversation of carbon and nitrogen during composting bring about loss, emission low product quality. Therefore, this study explored biochar (5%, 10%, 15%) on the microcosmic mechanism transformation humification manage co-conversation carbon. Results showed that addition 10% 15% prolonged thermophilic period (>55°C) at least 3 days than control, final NH4+-N three times lower control in treatments, NO3--N 3.5 higher 15%-treated experimental group control. both contributed significantly degree retainment, with contributing most. High-throughput sequencing demonstrated Firmicutes Proteobacteria were dominating species throughout process, adding enhanced abundance species, especially Pseudoxanthomonas Firmicutes. As a bacteria involved metabolism amino acids, 10 percent additions increased by 22.9% group. A Nitrobacter SBR1031, nitrifying contributes converting ammonia nitrate, identified compost treated biochar. results promoted mineralization adsorbing influencing microbial community structure. Especially when treating wet material waste, 10%-15% could advance high-temperature period, improve quality compost, reduce enhance fixation capacity, which is essential for production value-added fertilizers.

Abstract: Effective management practices can mitigate greenhouse gas (GHG) emissions during aerobic composting of manure. This study conducted four industrial-scale experiments at different environmental temperatures to comprehensively evaluate the effects emission reduction measures and semi-permeable membrane covering on GHG microbial community in cattle The found that NFC + OPT ISM reduced N2O by 21.44%–52.78% CH4 41.84%–72.34%, respectively, regardless temperature. was attributed downregulation AOA, nirS, mcrA gene abundances, upregulation nosZ abundance, a decrease Firmicutes 9.67%–54.28% process. Therefore, combination semipermeable represents novel strategy reduce global warming potential (GWP) modulating functional genes
