Abstract: Wastes generated from different tanneries are subjected to high risk of contamination due to the presence of toxic Cr (VI) that poses a serious threat to the environment and human’s wellbeing. It is very important that tannery waste in the form of sludge should be managed in an environmentally sound manner. The present endeavor had been undertaken to characterize the Bantala tannery sludge sample with respect to its chemical, microbiological and biochemical properties. Data revealed that the sludge was a rich source of plant nutrient with high enzymatic activities except its high concentration of chromium. Vermicomposting of the tannery sludge mixed with cow dung at different proportions (1:1 and 3:1) using Eisenia fetida suggested that the vermicompost could be a good source of plant nutrient with effective enzymatic activities and reduced concentration of chromium. The stability and maturity study of the vermicompost suggested that the vermicompost with ratio 1:1 was stable and mature compost than the ratio 3:1. The result inferred that vermicomposting of the tannery sludge could be a suitable way to reduce the high concentration of chromium of the raw tannery sludge.
