This study explores the potential of mitigating the harmful effects of TWW through sedimentation using clinoptiolite in the presence of various anionic, cationic and non-ionic flocculants with different molecular weights and charge densities followed by encapsulation in a brick structure for stability. Compressive strength (CS), size reduction after firing (SRAF), water absorption (WA) and colouring parameters of bricks were determined. X-Ray diffraction (XRD) and scanning electron microscopy (SEM)-energy dispersive X-ray (EDX) analyses were conducted on brick bodies. Kinetic leaching experiments were conducted for possible heavy metal release from the bricks. Bricks containing 10 wt% leather waste and 5 wt% clinoptiolite sintered at 800 °C instead of 920 °C possessed similar properties to the standard brick (SB). © 2017 Australian Ceramic Society.EnglishAll Open Access; Green Open AccessBrickmakingCompressive strengthFlocculationHeavy metalsLeatherPolyacrylatesScanning electron microscopySedimentationWater absorptionX ray diffractionClinoptioliteEnergy dispersive x-rayHarmful effectsHeavy metal releaseLeaching experimentsSize reductionsStandard bricksTannery wastewaterBrickArticle10.1007/s41779-017-0085-z
