Plastic is used in a wide range of application, thus generating a huge amount of plastic waste which is difficult to manage. Real life waste streams often consist of a complex mixture of plastic waste. Mixed plastic waste is a challenge for the recycling industry since different type of plastics tend to be incompatible when recycled together. Hence, microwave pyrolysis of mixed plastic is conducted to efficiently recover oil product and achieve the required plastics recycling rates. In this study, the interaction of iron metal of different shapes (powder and coil) was investigated. Three type of plastics that was, polystyrene (PS), polypropylene (PP) and low-density polyethylene (LDPE) were mixed together at a constant ratio of 1:1:1. The ratio of mass of iron powder (g) with the quantity of iron coil was varied as followed: 5:5, 10:5, 5:10 and 10:10. The pyrolysis of mixed plastic (PS, PP and LDPE) with iron powder and coil ratio at 10:5 yielded the highest oil product at 70.24 wt% followed by 65.19, 52.72 and 40.38 wt% for 5:10, 10:10 and 5:5 ratio. The heating mechanism of the different shapes of metal differed such that the metal powder absorbed the microwave radiation whereas the metal coil concentrated the microwave at its surface and reflected it. Synergistic effect between microwave absorption and reflection may result in higher rate of plastic degradation and higher oil yield.
