Abstract
Leather tanneries sludge is categorized under hazardous waste owing to its properties comprising of organic content, chloride, heavy metals, and pathogenic occurrence. The main objective of the present study was to assess the sustainable vermiconversion of tannery sludge in its raw state employing Eisenia fetida over eight-week trial. No mortality with positive growth of 10–30% was attained in all the reactors. Total carbon, pH, and C:N ratio decreased from initial in the range of 12–23.5, 3–17, and 31–55%, respectively, in the final products. Electrical conductivity, salinity, and total nitrogen showed a substantial increase from initial in all trials. A significant decrease of 75–99.5% was attained in the pathogenic load of both total and fecal coliforms from initial in all the reactors. The vermicomposting process has the potential to stabilize and convert hazardous industrial tannery sludge into quality organic manure of agronomic importance without any adverse effect on the earthworms.
