title: Vermiremediation of dyeing sludge from textile mill with the help of exotic earthworm Eisenia fetida Savigny.
abstract: The aim of present study was for the vermiremediation of dyeing sludge from textile mill into nutrient-rich vermicompost using earthworm Eisenia fetida. The dyeing sludge was mixed with cattle dung in different ratios, i.e., 0:100 (D0), 25:75 (D25), 50:50 (D50), 75:25 (D75), and 100:0 (D100) with earthworms, and 0:100 (S0), 25:75 (S25), 50:50 (S50), 75:25 (S75), and 100:0 (S100) without earthworms. Minimum mortality and maximum population build-up were observed in a 25:75 mixture. Nitrogen, phosphorus, sodium, and pH increased from the initial to the final products with earthworms, while electrical conductivity, C/N ratio, organic carbon, and potassium declined in all the feed mixtures. Vermicomposting with E. fetida was better for composting to change this sludge into nutrient-rich manure.
