| Abstract: |
| Research on the mechanisms and mitigation technologies of ammonia and greenhouse gas emissions during livestock waste composting are hot topics for domestic and foreign scholars in the past 30 years. The conversion of carbon and nitrogen and emissions of ammonia and greenhouse gas during the composting process are interrelated. Previous studies mainly focus on ammonia volatilization, however, a systematic research on the synergistic mitigation of ammonia and greenhouse gas emissions is lack. Here, this paper conducted a systematic analysis on the published papers, to analyze the emission mechanism and synergetic relationship of ammonia and greenhouse gas emissions during livestock waste composting; to elaborate the influencing factor, regulation pathway and mitigation potential of mitigation technology; to explore the technical pathway of synergistic mitigation of gas emissions; to provide the outlook for synergistic mitigation mechanism and mitigation strategy. To date, synergistic mitigation mechanism and regulation pathway of ammonia and greenhouse gas during livestock waste composting are unclear. In the future, chemical additives, physical additives and microbial additives should be applied on the basis of adjusting material properties and optimizing gas supply strategies. |
