Information on prospective metal remediation by Eudrilus eugeniae during vermicomposting of cotton textile sludge (CTS) is rather scarce. This investigation, therefore, evaluates the sanitization efficiency of this species in CTS and CTS + cow-dung (CD) based feedstocks against aerobic composting. Accordingly, reduction in Pb, Cd, Cr, and Zn concentrations was between 50 and 70% under vermicomposting. Budget equations substantiated that humic compound mediated chelation was the dominant route of metal removal, against nominal bioaccumulation by earthworms. Correlation statistics revealed that formation of humic compounds (humic acid, fulvic acid, and humin) greatly influenced the transition of toxic Cr⁶⁺ to benign Cr³⁺ during vermicomposting. Moreover, increase in total N content and P availability was significantly greater under vermicomposting than composting. Thus, E. eugeniae efficiently stabilized the feedstocks by reducing pH, Ca, S, and organic C and CTS + CD(2:1) was the most favorable feedstock for E. eugeniae vermicomposting in respect of metal detoxification and nutrient stabilization.

棉纺织污泥（CTS）的堆肥过程中，Eudrilus eugeniae进行的预期金属修复的信息很少。因此，这项研究评估了该物种在CTS和CTS +牛粪（CD）原料中对有氧堆肥的消毒效果。因此，在ver堆肥中，Pb，Cd，Cr和Zn的浓度降低了50％至70％。预算方程式证实，腐殖质化合物介导的螯合是去除金属的主要途径，与nominal的名义生物积累相反。相关统计表明，腐殖酸化合物（腐殖酸，富里酸和腐殖质）的形成极大地影响了有毒Cr ⁶⁺向良性Cr ³⁺的转化。在vercomcomposting期间。此外，在ver堆肥中，总氮含量和磷的利用率显着高于堆肥。因此，E. eugeniae有效地通过降低pH值，钙，硫，和有机碳和CTS + CD（2：1）稳定化的原料是最有利的原料E. eugeniae蚯蚓就该金属解毒和养分稳定。
