Synthetic plastics are ubiquitous across various industries and in everyday life, offering convenience in numerous applications. Among these, polyethylene terephthalate (PET) stands out as one of the most widely used synthetic plastics, with its consumption steadily increasing. However, the substantial volume of PET plastic waste discharged into the environment annually necessitates an effective solution for its management. This study focuses on repurposing PET waste plastic to produce activated carbon using a chemical activation method, employing H3PO4 acid as the activating agent. The research investigates the influence of factors such as the impregnation rate of PET waste plastic with H3PO4, activation temperature, and activation time on the surface area of the resulting activated carbon. The characterization of the produced activated carbon was conducted through scanning electron microscopy (SEM), X -ray diffraction (XRD), Fourier -transform infrared spectroscopy (FTIR), and Brunauer -Emmett -Teller (BET) analysis.
