Consumption rate of liquid fuel, in Indonesia continuosly increase. Despite fuel supply in Indonesia decrease. On the other hand, Indonesia also faces waste problem. Plastic waste in Indonesia has reached up to 5.4 tons per year in 2008. The solution to overcome both problems is by using technology that can convert plastic waste into renewable energy. One of the technology is pyrolysis.This study aims to determine the potential of plastics LDPE, PET and PS in the pyrolysis process to produce alternative fuel. Types of plastic that be used in this research are LDPE (Low Density Polyethylene), PET (Poly Ethylene Terephthalate), and PS (Polystyrene).The pyrolysis process were carried out at temperature <400 °C for 2 hours in batch reactor. Based on preliminary study, plastics that suitable for pyrolysis process are LDPE and PS. In the pyrolysis process, it was found that LDPE pyrolysis produce 498.34 g/kg of oil, which majority of oil produced. Highest propotion of non-condensable gases and charchoal are produced by PS pyrolysis. Charcoal from LDPE, PET and PS pyrolysis have calorific value between 29 MJ/kg and 47 MJ/kg, thus those char are suitable as alternative solid fuels.The oil produced vary in quality. The best quality of oil is produced by LDPE pyrolysis that has quality close to the commercial petroleum due to its calorific value, density, and viscosity. PS pyrolysis produced highest concentration of NOx, CO and SO2, however the concentration of gases don’t exceed the standard quality of air emission of incinerator that attached on Keputusan Kepala Bapedal No.3 tahun 1995. Although pyrolysis can produce alternative fuel, yet in this research it has difficulty in operational and poor economic value.
