Abstract Tannery sludge contains significant amount of various metals. These metals containing tannery sludge management has become a great challenge for the survival of tanning industry. The aim of this work was to remove metals especially chromium (Cr) from the thermally treated tannery sludge with a possible way of decontaminating without any chemical treatment for safe disposal. Tannery sludge was thermally treated at 100 to 1000 °C with an interval of 100 °C for 4 h and metals removal was assessed through the Toxicity Characteristic Leaching Procedure (TCLP). The presence of metals in aqueous solution was quantified by Flame Atomic Absorption Spectrophotometer (FAAS). Results indicate that Cr removal from the thermally treated tannery sludge was minimum at low temperature (
