Usage of polyvinyl chloride (PVC)-coated and PVC-based materials has increased worldwide. Particularly, short-term, usable PVC-based flexible banners present significant environmental concerns when freshly disposed of due to their inherent toxicity and limited recyclability. This study presents a solvent desorption and extraction method for extracting and characterizing PVC from waste banners (WB), aiming to advance material recovery within a circular plastic economy framework. This extraction process successfully yielded four distinct components: reinforced fibers (RFs), solvent-soluble parts (SSPs), centrifuged liquid parts (CLP), and extracted polyvinyl chloride (ePVC). Successfully, 34.3% of ePVC from the total mass of WB, where only 0.08% mass loss was calculated. The structural analysis, conducted via FTIR, revealed that the ePVC closely resembled virgin PVC. Additionally, a minor carbonyl (C=O) stretching peak at 1727 cm-1 was observed, indicating the presence of residual plasticizers or phthalate derivatives. The ePVC demonstrated 81.44 mL/g intrinsic viscosity, where the K-value was 60.9, the melting point was 200 °C, and the electrical conductivity was 50.29 µS. The qualitative values suggest viability for fundamental physicochemical properties and industrial reuse. Overall, the findings validate the potential of this approach as an environmentally responsible recycling strategy and a promising alternative to incineration or landfilling of PVC-based waste.
