The influx of textile waste effluents into waterways poses threat to the flora and fauna inhabiting the aquatic habitat and general health of the public residing in that area. This study was an attempt to convert the DIS (Dye industrial sludge) into vermicompost, which in turn could be used to improve the physical, chemical and biological properties of the soil. Resultantly, could also enhance the plant growth yield. DIS at 5 g/kg, 10 g/kg, 20 g/kg, 30 g/kg and 40 g/kg concentrations were subjected to composting using Eudrilus eugeniae. The physico-chemical analyses of the vermitreated DIS reveal significant enhancement in the N and Fe in all the treated groups when compared to the control. On the other hand, significant elevation in K, Ca, Mg, Pb and Mn was evinced at 40g / kg vermicompost of DIS when compared the control and other treated groups. Significant elevation in phenol content of vermitreated DIS was evident at 40 g/kg and 30 g/kg when compared to the control and other treated groups. DIS at 40 g/kg 30 g/kg and 10 g/kg exhibited significant elevation in the phosphorus content on vermitreatment with Eudrilus eugeniae when compared to the control and other treated groups. pH of DIS shifted towards acidity on composting with Eudrilus eugeniae.
