This research aims to study the co-pyrolysis of plastic waste and sugarcane leaves by operating in a horizontal fixed bed reactor heated by an electrical furnace. The pyrolysis conditions were the weight ratio of plastic waste to sugarcane leaves (P:B) of 0:1 1:0 1:1 3:1 and 1:3, spent DCC catalyst amount of 0-20wt% and maintaining for 3 h at a pyrolysis temperature of 400-600°C. It was found that thermal degradation depended on the material ratio and the pyrolysis temperature. The noncatalytic co-pyrolysis of 3:1 (P:B) gave high liquid product yield of 47.67wt%. Addition of catalyst in co-pyrolysis decreased the liquid product yield. However, FTIR curves of liquid product from co-pyrolysis showed similarities with those of commercial diesel and gasoline. Liquid products with high heating values of 78.23 and 85.97 MJ/kg were obtained from the co-pyrolysis of 3:1 (P:B) at 600°C with catalyst amount of 5 and 10wt%, respectively. GC-MS analysis showed that the liquid product obtained from the co-pyrolysis at 600°C for the 1:1 (P:B) and 3:1 (P:B) with the 5 and 10wt% catalyst, respectively, increased the light aliphatic hydrocarbon distribution of the range C9-C21.
