| dc.description.abstract | Recently, the waste issues has been the concern of the industry which produces the waste in its production process, particularly when it the produces the toxic and harmful material. During this time, the management of toxic and harmful waste is the duty of PT. Persada Pemusnah Limbah Industri (PPLI) which requires considerable cost. To minimize the cost incurred for the waste management, it is better to take benefit from the waste. The research is aimed at identifying the heavy metal mobilized in the ceramics mixed with catalyst waste and additive material. In addition, this paper also identifies the refraction level, water absorbance and the optimum waste addition in preparing the ceramics. The method adopted was solidification of catalyst waste as ceramics. In the process of solidification, the increments of catalyst waste concentration were 0%, 5%, 10%, 15% an 20% in the ceramics material. Further, the concentration was added with water and molded with the size of 10 x 10 x 1 cm. the molded ceramics was air-dried and burned at 1200°C for 16 hours, each experiment variation consisted of 25 ceramics sample. The test conducted for the refraction level, water absorbance andalkali testusing TCLP method. The increment of catalyst (RCC-15) in the material for the ceramics preparation indicated the positive result. The result search show that there was an increment in the water absorbance of the ceramics without catalyst (9,88%) and those with catalyst 20% (11,90%). This condition are influenced by bonding catalyst the other e material was slightly lower compared to chaolin. Therefore, the resulting ceramics density was smaller. The refraction test on ceramics revealed that the ceramics with no catalyst had the refraction of 130,73kg/cm² until the increment ofthe catalyst of 20% had the refraction up to 109,13 kg/cm², the addition of catalyst up to 20% yielded the higher refraction than the referent ceramics available in the market, such as Mulia ceramics, KIA and Diamond was the refraction levels of 29,25 kg/cm², 31,69 kg/cm², 21,94 kg/cm². TCLP test revealed varied result. The concentration of the heavy metal (Pb, Cr, Zn Ni an Cu) was still bellow the determined standard quality (P.P No 85 of 1999) concerning the management of toxic and harmful material. The overall result indicated the exploitation of catalyst waste as the ceramics mixture was relatively safe and fulfilled the standard, both physically (water absorbance and refraction) and chemically (TCLP test) | en_US |
