The present study observes the chance that vermicomposting of DIS could be beneficial for agriculture and it turn reduce the pollution load. In the exploration, five different concentration of DIS: 5 g/kg, 10 g/kg, 20 g/kg, 30 g/kg and 40 g/kg were vermitreated employing the earthworm Perionyx excavatus and the physico-chemical nature of the DIS was elucidated. Significant elevation in pH was evinced in all the vermitreated DIS. Statistically significant increase in phosphorus (30 g/ kg and 40 g/ kg), K ( 40g/ kg), Ca ( 30g/ kg and 40g/ kg),Cu ( 30g /kg and 40g/ kg ), Fe (40g / kg), Mg ( 40g/ kg), Mn ( 40g/ kg and 30g/ kg), Cr (40g/ kg, 30g/ kg , 20g/ kg and 10 g/ kg) was observed in vermitreated DIS when compared to untreated DIS. Significant elevation in Zn, Pb and phenol was registered in all the vermitreated DIS when compared to the control group. On the other hand, significant decline in N was recorded in vermitreated DIS when compared to untreated one. No changes in Electrical Conductivity (EC) was noticed irrespective of composting the DIS with Perionyx excavatus and untreated DIS
