This research was performed to evaluate the recycling characteristics by physico-chemical analysis of the wasted andthe reclaimed rubbers. Two types of the powdered and the reclaimed rubbers were sampled and analyzed. Pb was detectedin the range of 2.55~194.00mg/kg for the powdered rubber product, of which some exceeded the rubber standard criteria(90mg/kg), while it was 0.05~50.80mg/kg for the reclaimed rubber. Zn showed the highest concentration of heavymetals in the rubber products, comparing to the other heavy metals. It ranged from 9,750mg/kg to 27,900mg/kg, and388mg/kg to 17,450mg/kg for the powdered and the reclaimed rubber products, respectively. Total PAHs concentrationsof the powdered and the reclaimed rubber products exceeded greatly the rubber standard criteria (10mg/kg) as221.7~18,842.8mg/kg and not-detected~14,248.0mg/kg, respectively. Therefore, it was concluded that the managementplan and environmental criteria should be prepared for the recycled rubber product, considering the concentrations ofhazardous compounds such as Pb, Zn, and PAHs.
