Abstract

In China, the treatment of agriculture residue and food waste is of great concern. Aerobic composting is gaining increasing attention because it can improve both organic waste recycling and soil remediation. The aim of this study was to evaluate the composting process of the mixture of wheat straw and food waste, and the effect of microbial agent on the degradation process. Results showed that typical temperature variation curves were observed with peak values at 65.8ºC and 60.5ºC with and without inoculation, respectively. VS, DOC, NH4 +-N and C/N decreased over the composting process, while pH, EC, NO3--N and GI showed an opposite trend. The microbial community diversity was analyzed and Firmicutes, Proteobacteria, Actinobacteria, Bacteroidetes and Ascomycota enriched in the compost. At the end of the composting process, the maturity was indicated by the finial C/N ratio and GI which reached 11.26±0.84 and 144.68±14.95% with inoculation. Inoculation had a positive effect on composting performance but is less economic.
