The present study has aimed to evaluate the role of vermitechnology in the qualitative enrichment of compost during the valorization process of solid paper mill wastes. A maximum mass reduction of 77% (primary sludge) and 76% (secondary sludge) were noticed through thermogravimetric (TG) analysis. The biodegradation of complex xenobiotics such as lignin, cellulose, etc. were found in spectral bands of FTIR spectroscopy which had attributed to extent of mineralization among compost samples. A significant correlation between the decrease of the C/N ratio and the rise of the 2921/1633 peak ratio of FTIR had conferred the maturity among vermicompost samples. Furthermore, the presence of different macromolecular humic acid-like substances such as benzene dicarboxylic acid, propanedioic acid, glutaric acid, etc. was found in the vermicompost samples through GC–MS analysis. In addition to such qualitative enrichment, microbial diversity was manifested using PLFA biomarkers which had revealed a huge bottleneck in terms of microbial populaces designating ecological succession upon vermicomposting. Therefore, the present study can be considered as a comprehensive eco-biochemical approach which will open up a new vista the importance in context to paper mill solid waste management.

本研究旨在评估在固态造纸厂废物增值过程中，蠕虫技术在堆肥质质富集中的作用。通过热重（TG）分析发现最大质量减少量为77％（主要污泥）和76％（次要污泥）。在FTIR光谱的光谱带中发现了复杂的异质生物如木质素，纤维素等的生物降解，这归因于堆肥样品之间的矿化程度。C / N比的降低与FTIR的2921/1633峰值比的升高之间存在显着的相关性，这赋予了com石样品之间的成熟度。此外，存在不同的大分子腐殖酸样物质，例如苯二甲酸，丙二酸，戊二酸等。通过GC-MS分析发现在com杂样品中。除了这种定性的富集外，使用PLFA生物标志物还可以显示微生物多样性，这表明在pop虫侵染后指定生态演替的微生物种群方面存在巨大的瓶颈。因此，本研究可以被认为是一种综合的生态生化方法，它将为造纸厂固体废物管理开辟新的前景。
