One of the generally applied filler in rubber industry is commercial chalk—divided calcium carbonate. In aim to prevent from the agglomeration of calcium carbonate particles during mixing with rubber, calcium carbonate is modified. It rely on changing hydrophilic properties on hydrophobic properties acting surfactants as higher fatty acids, their salts, esters, higher aliphatic liquor, vegetable oils, or amine. The aim of present studies was to separate chalk and precipitating degraded proteins and fats about nano‐sized from two kind of environmentally noxious tannery effluents which came from processes of liming with degradation of hair structure. Obtained deposits were examined by FTIR spectroscopic, particles size measurements, zeta potential, microanalysis and then these deposits were used as fillers of rubber mixes such as NBR and XNBR. © 2009 Wiley Periodicals, Inc.
