The growing accumulation of plastic waste has prompted the need for effective waste-to-energy technologies. This study investigates the integrated pyrolysis-gasification process for plastic waste conversion, aiming to enhance energy recovery and reduce environmental impact. Pyrolysis is employed to decompose plastic polymers into volatile compounds, which are subsequently processed in the gasification phase to produce syngas. The integration of these two thermochemical processes enables a more efficient and sustainable conversion of plastic waste into valuable energy products. Various plastic waste types, including polyethylene, polypropylene, and polystyrene, were subjected to pyrolysis at different temperatures to evaluate the yield and composition of the resulting volatile compounds. The produced gases and char were then subjected to gasification, examining their suitability for syngas generation and the efficiency of energy conversion. The study also assesses the environmental implications of this integrated approach, including the reduction of landfill burden and the potential for lower emissions compared to conventional plastic waste disposal methods. Results demonstrate that the integrated pyrolysis-gasification process enhances the energy yield and reduces environmental concerns, offering a promising pathway for sustainable plastic waste management and energy production.
