Abstract: The present study aimed for the conversion of textile industrial sludge (TIS) amended with the cow dung into vermicompost operated by the epigenic earthworm Eudrilus eugeniae. To accomplish the intent of the experiment, the substrate was allowed to decompose for 30 days, under monitored environmental conditions. Three different combinations were prepared (V25%, V50%, and V75%) from TIS, and compared with Vagro (vermicompost prepared from agricultural waste) and Vsoil. Among the entire three treatments, V75% was shown by physicochemical parameters for Trigonella foenum (Fenugreek/Methi) plant growth, seed germination, and leave production in the tested pot. The maximum amount of available nitrogen, phosphorus, potassium (NPK) was recorded at V75%. On the other side, toxic metal (Cr, Mn, Cu, Pb Cd, and Zn) concentrations were diluted to minimum levels. The result advised that vermicomposting consider one of the alternative methods for waste management and energy recovery from industrial waste.
