| Saudi Arabia is one of the major producers of plastic in the world with total production capacity of around six million metric tons per year. The amount of plastic wastes in Saudi Arabia is about 15wt% in the composition of domestic municipality waste. Saudi Arabia is also one of the largest oil producing country in the world. The pyrolysis of mixed plastics has been considered as an effective way to convert waste plastics into useful hydrocarbon liquid products. First, a series of thermal cracking of all plastics was carried out individually in a micro autoclave reactor under nitrogen atmosphere in order to establish their thermal behavior. It was found that on the pyrolysis of all six plastics; only PS undergoes to maximum cracking and produces maximum amounts of liquid products. Therefore, in second step of the binary thermal reactions of individual HDPE, LDPE, PP and PET with PS was conducted. Third, the binary catalytic reactions of individual HDPE, LDPE, PP and PET were carried out with PS and catalyst. The results obtained from of this study, so far, shows usefulness and feasibility of the pyrolysis process of the mixed plastic wastes as an alternative approach to feedstock recycling. |
