摘要： Greenhouse gas (GHG) emissions during aerobic composting are unavoidable, but effective additives can significantly reduce emissions. Hence, this study intended to investigate the influence of different engineered biochar, modified with various materials (MgO, NaOH, Na2SiO3, and HNO3), on GHG emissions, bacterial community structure, and eco-efficiency during the co-composting process of chicken manure (CM) and bagasse. Six treatments were established, including a control (CK, a mixture of CM and bagasse), as well as treatments incorporating biochar (BC), MgO-biochar (MOBC), NaOH-biochar (SHBC), Na2SiO3-biochar (SSBC), and HNO3-biochar (NABC), respectively. These treatments underwent aerobic composting for 35 days. The findings show that engineered biochar significantly reduced GHG emissions compared to CK. Specifically, MOBC achieved a substantial 66.31 % reduction in cumulative NH3 emissions, while SHBC recorded the lowest cumulative N2O emissions. Furthermore, after composting, the MOBC treatment resulted in a significant increase of 75.72 % in amino acid nitrogen and an even more pronounced increase of 1516.02 % in amino sugar nitrogen. In contrast, the SSBC treatment led to increases of 66.81 % in amino acid nitrogen and 253.53 % in amino sugar nitrogen. The Mantel test revealed that the combination of Luteimonas, Persicitalea, and Taibaiella bacteria significantly influenced the levels of NH4+-N and organic nitrogen. Regarding GHG emissions and nitrogen retention, the ecoefficiency analysis demonstrated that MOBC exhibited superior performance, suggesting its potential as an effective material for enhancing the eco-efficiency of the co-composting process.
