论文摘要	Growing demand for intensive animal farms and increased public awareness of environmental friendliness, have led to continuous iteration and refinement of the initially crude composting technology. However, the impact of the composting facility and energy input on eco-efficiency is limited. In this study, a LCA approach was conducted to investigate the eco-efficiency of four widely applied composting strategies: static heaps (SH), windrow composting (WC), membrane-covered composting (MC) and reactor composting (RC). The results showed that the environmental benefits of RC's were decreased by 11.3%, 21.7%, and 6.5% compared to SH, WC, and MC, respectively. Advanced composting technologies didn't substantially reduce direct economic costs, however, the eco-efficiency of RC was increased by 296.9%, 54.7%, and 87.6% compared to SH, WC, and MC, respectively. Overall, the results demonstrate that RC is a promising solution with high ecological efficiency that can contribute to the sustainable development of intensified livestock production.
