In this research, the relevance of polymers in our daily lives, in the industrial market, in the development of new technologies, and the harmfulness of the waste generated by these polymers to human health and the environment are observed. By applying and analyzing techniques such as thermal analysis, microscopy, spectroscopy, and diffraction, we explore a composite that contains polymers, organic residues, and metallic residues. Thermal analysis, microscopy, spectroscopy, and diffraction highlight essential behaviors of the material for a process focused on sustainability. Understanding the characteristics of this type of material is crucial for developing processes that transform polluting materials into relevant and economically viable products, with the aim of mitigating human health impacts and environmental impacts. This research validates the use of thermal analysis, microscopy, spectroscopy, and diffraction techniques to characterize and understand complex polluting composites and enhance their applications in new processes and consequently in new sustainable products worldwide, respecting and preserving the environment for future generations.
