AB - The energy recovery of plastic waste provides a sustainable solution the growing accumulation of these materials in the environment. In this study, a pyrolysis-gasification model was developed using ASPEN PLUS to investigate the effect of gasification reactor temperature on the products generated from the thermal conversion of three waste types: polyethylene, polyethylene terephthalate, and used tires. The results show that increasing the temperature favors the formation of synthesis gas (hydrogen and CO), while the production of liquids and CH₄ significantly decreases beyond 800 °C. Polyethylene proves to be particularly efficient for hydrogen generation, whereas polyethylene terephthalate exhibits near-complete conversion gas at elevated temperatures. Although NH₃ production remains limited, it is affected by the nitrogen content of the feedstock, especially in tires, and by the presence of hydrogen, which may interact under extreme conditions. These findings can assist industrial operators in optimizing gasification conditions for syngas production, thereby contributing to waste-to-energy development and circular economy strategies.
