In this study, the pyrolysis of expanded polystyrene, polypropylene/polyethylene, and high impact polystyrene plastic waste from WEEE (electronic & electrical equipment) and C&D (construction and demolition) are studied at various temperature (500-600 oC) using dolomite to determine the maximum liquid phase with minimum halogen content. The products are assessed by thermo gravimetric analysis, pyrolytic-gas chromatography mass spectrometry, X-Ray fluorescence analysis and gas chromatography flame ionization. Heating values are calculated by automated bomb calorimetry and differential scanning calorimetry. The outcome of the dehalogenation experiments exhibits lower halogenated contents with maximum liquid product at lower temperature and in the presence of dolomite additive
