The increasing demand for poly(ethyleneterephthalate) (PET) polymer, the simultaneous shortage in landfill disposal spaces, and known problems associated with PET waste specifically (e.g., its nonbiodegradability and huge accumulation) are challenges with which mankind must cope nowadays. In this study, PET postconsumer bottle wastes were cut to very small slides and then subjected to an aminolysis process with ethanol amine as a degradative agent in the presence of one catalyst from three used in this study. The reaction was performed in sunlight: a beneficial, clean, cheap, and renewable source of energy. The end product, which was a white precipitate precipitate of bis(2-hydroxyethylene) terephthalamide, was subjected to spectrophotometric and thermal analyses. The product was characterized to assess its suitability for use in pigments in anticorrosive paint formulations. In general, this process was a green, environmentally friendly degradation based on the utilization of solar energy for the aminolysis reaction using simple, cheap, available chemicals as catalysts. The originality of this study was derived from the use of waste materials to yield a product with beneficial applications in the field of corrosion inhibition
