Abstract
The various chemicals in industrial wastewater can be beneficial for improving its circularity.
If extraction methods are used to capture valuable components from the wastewater and then
recirculate them throughout the process, the potential of the wastewater can be fully exploited. In
this study, wastewater produced after the polypropylene deodorization process was evaluated. These
waters remove the remains of the additives used to create the resin. With this recovery, contamination
of the water bodies is avoided, and the polymer production process becomes more circular. The
phenolic component was recovered by solid-phase extraction and HPLC, with a recovery rate of over
95%. FTIR and DSC were used to evaluate the purity of the extracted compound. After the phenolic
compound was applied to the resin and its thermal stability was analyzed via TGA, the compound’s
efficacy was finally determined. The results showed that the recovered additive improves the thermal
qualities of the material.
