CleanMat, EarlyView.Oyster shell (OS) as a sustainable calcium source for chromium recovery from tannery sludge via co‐pyrolysis. OS outperformed CaCO3, achieving > 95% Cr recovery, attributed to its organic matrix proteins enhancing adsorption and phase conversion. The oxidation of tannery sludge Cr(III) to Cr(VI) improved recyclability, aligning with circular economy ...
