| Abstract Scope |
The inadequate disposal of polymeric materials, such as High-Density Polyethylene (HDPE) present in oil and gas industry pipelines, represents a significant environmental challenge. The search for effective and sustainable reuse solutions is, therefore, essential. This research evaluates the mechanical, physical, and chemical properties of recovered High-Density Polyethylene, originating from the same location and decommissioning context as the original material. For this purpose, comprehensive tests will be conducted: Shore D hardness, tensile strength, density, Fourier-transform infrared spectroscopy (FTIR), wettability, dilatometry, differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). The results indicated that the post-use High-Density Polyethylene maintains adequate properties, validating its potential for successful reintroduction into production chain. This approach aims not only to mitigate the environmental impact of waste disposal but also to generate substantial economic value, transforming a liability into a valuable resource. The material's viability and the promotion of the circular economy are central pillars of this study. |
