Analytical pyrolysis (Py-GC/MS) was used to study complex composting processes. The technique was first validated for reproducibility and finally applied to assess the efficiency of a microbial bio-accelerator product (CBB) in composting organic residues with different composition. Fresh lignocellulosic and urban wastes were treated with CBB and the composting kinetics studied to investigate the transformations undergone in the course of biocomposting. Our findings demonstrate that these changes, as well as the efficiency of CBB, can be monitored through the molecular characterization of the released pyrolysis products. The CBB bacterial product effectively seems to favour composting accelerating the process and shorten composting time. Analytical pyrolysis was informative in assessing to which extent compost transformation reached an acceptable stabilization point. The technique could be also developed into a semi-quantitative tool to monitor changes of main organic matter components (polysaccharides, proteins, lignin, lipids, etc.) as composting proceeds.
采用分析热解（Py-GC/MS）技术研究复杂的堆肥过程。该技术首先进行了重现性验证，最终用于评估一种微生物生物促进剂产品（CBB）在堆肥不同成分有机残留物方面的效率。用CBB处理新鲜木质纤维素和城市废物，并研究堆肥动力学，以探究生物堆肥过程中发生的转化。我们的研究结果表明，这些变化以及CBB的效率可以通过对热解产物进行分子表征来监测。CBB细菌产品似乎有效地促进了堆肥，加快了进程并缩短了堆肥时间。分析热解对于评估堆肥转化达到可接受稳定点的程度很有参考价值。该技术还可以发展成为一种半定量工具，以监测堆肥过程中主要有机物质成分（多糖、蛋白质、木质素、脂质等）的变化。
