Benzophenone (BP) and its derivatives are extensively used as ultraviolet filters in modern society and increasingly being released into the environment. Co-composting of food waste with sawdust and mature compost was successfully demonstrated to treat high BP concentration (927 $\pm$ 229 mg kg⁻¹), with a removal efficiency of 97% after 35 days of incubation. The highest biodegradation rate of 55 mg kg⁻¹day⁻¹ was observed at the thermophilic stage. The biodegradation followed second-order kinetics, and the half-life of BP was 1.3 days during the co-composting process. Additionally, malodorous gas emissions from the co-composting process were also analyzed. The malodorous compounds, including ammonia (NH₃), hydrogen sulfide (H₂S), and volatile organic sulfide compounds (VOSCs), peaked at the thermophilic phase. NH₃ and H₂S were the main components contributing to 92% and 7.6% of the total malodorous concentration (617 ppm). Dimethyl disulfide (28.9 ppb) and dimethyl sulfide (23.5 ppb) concentrations accounted for $\sim$58.9% of the total VOSC emitted. The malodorous emissions were positively correlated with temperature, pH, and negative with oxygen content during the co-composting. Sawdust and mature compost enhanced oxygen penetration in the compost mixture and thereby reduced odor emission. These results support that co-composting could be a technically and economically feasible treatment technology for the degradation of BP and can be used to treat other emerging organic pollutants.

二苯甲酮（BP）及其衍生物在现代社会中广泛用作紫外线滤光片，并日益释放到环境中。已成功证明餐厨垃圾与木屑和成熟的堆肥共同堆肥可处理高BP浓度（927 $\pm$孵育35天后，去除效率为 229 mg kg ^-1），去除效率为97％。在嗜热阶段观察到最高的生物降解速率为55 mg kg ^-1天^-1。生物降解遵循二级动力学，在共同堆肥过程中，BP的半衰期为1.3天。此外，还分析了混合堆肥过程中产生的恶臭气体。包括氨气（NH ₃），硫化氢（H ₂ S）和挥发性有机硫化物（VOSCs）的恶臭化合物在嗜热相达到峰值。NH ₃和H ₂S是占总恶臭浓度（617 ppm）的92％和7.6％的主要成分。二甲基二硫（28.9 ppb）和二甲基硫（23.5 ppb）的浓度占$〜$排放的VOSC总量的58.9％。在共堆肥过程中，恶臭排放与温度，pH呈正相关，与氧含量呈负相关。木屑和成熟的堆肥增加了氧在堆肥混合物中的渗透，从而减少了气味的散发。这些结果表明，协同堆肥可以作为一种技术和经济上可行的降解BP的处理技术，并可以用于处理其他新兴有机污染物。
