In this work, waste tetra pak (WTP) and waste motor oil (WMO), with different blend ratios of WTP/WMO (4:1, 2:1, 1:1, 1:2, 1:4) were subjected to co-pyrolysis at 500 degrees C. For the purpose of comparison, individual pyrolysis of WTP and WMO was conducted under identical conditions. Pyrolysis/co-pyrolysis products were collected as liquids (containing an oil phase and an aqueous phase), solid residue, and gaseous products. The highest oil yield was 72.14 wt % and was obtained at a blend ratio of 1:4 (WTP/WMO). Synergistic effects on oil yields were observed in all blends. Heating values of the oils from blends ranged from 45.2 to 46.1 MJ kg(-1). The heating value of the gas product obtained from the co-pyrolysis of WTP with WMO at a blend ratio of 1:1 (WTP/WMO) was 24.5 MJ Nm(-3). Heating values of the solid residue ranged from 24.2 to 26.7 MJ kg(-1), comparable to that of sub-bituminous coal. These results suggest that WTP could be co-pyrolyzed with WMO to produce liquid, solid, and gaseous fuels.
