Respiration indices (dynamic and cumulative) and the anaerobic biogasification potential are applied to the quantitative calculation of the biodegradation efficiency in a combined anaerobic/aerobic treatment for the organic fraction of municipal solid waste (OFMSW). They also permit to observe possible deficiencies in some parts of the entire sequence of organic matter decomposition. On the contrary, chemical methods presented a limited utility. Dynamic respiration indices highlighted that anaerobic digestion was the most efficient step to reduce the respiration activity of the waste (61% calculated on a DRI(24h) basis). Respirometric activity of final compost was 93% lower than initial OFMSW confirming the overall efficiency of the plant studied and the stability of the final product (0.3g O(2) kg TS(-1)h(-1)). Finally, the use of an advanced methodology such as the Diffuse Reflectance Infrared Fourier Transformed (DRIFT) allows the determination of the main functional groups of organic matter, which significantly change during the biological treatment of organic matter.
呼吸指数（动态和累积）和厌氧生物沼气潜力被应用于城市固体废物（OFMSW）有机部分的联合厌氧/好氧处理中生物降解效率的定量计算。它们还可以观察到整个有机物分解序列中某些部分可能存在的缺陷。相反，化学方法的应用具有一定的局限性。动态呼吸指数突出表明，厌氧消化是降低废物呼吸活性的最有效步骤（基于 DRI(24h)计算为 61%）。最终堆肥的呼吸活性比初始 OFMSW 低 93%，这证实了所研究工厂的整体效率和最终产品的稳定性（0.3g O(2) kg TS(-1)h(-1)）。最后，使用漫反射红外傅里叶变换（DRIFT）等先进方法可以确定有机物的主要官能团，这些官能团在有机物的生物处理过程中会发生显著变化。
