Pyrolysis of aluminum plastic package waste based on tube-furnace experiment

The pyrolysis and combustion characteristics of a aluminum-plastic composite package were studied by thermal analysis and on a tube-furnace. The experiments were performed in N ₂ atmosphere, 10% oxygen concentration and air atmosphere respectively. XRD analysis was further performed to identified the residue substance and its mineral phase. The results show the optimum pyrolysis temperature of a aluminum-plastic composite package is in the range of 600-700°C. The weight loss of APCP materials were in the range of 88.32-89.15% under a constant temperature of 600 °C and 650 °C for 1 h. The residue substance of APCP pyrolysis products were major Al and small amount of Al ₂O ₃ and AlN.
