| Abstract | ||||
| Utilization of recycled polymers and solid waste into useful products is targeted for controlling greenhouse gas emissions. The aim is to prepare and apply novel and boosted environmentally friendly composites as full waste-based sources based on recycled polyvinyl chloride (PVC) matrix, waste-based plasticizer (P), and green CaCO3 nanofiller (F). Respectively, P and F improvers were obtained via the glycolysis of polyethylene terephthalate (PET) waste and from eggshells solid waste. Selected concentrations of composites were extruded and then hot-pressed. FTIR, XRD, and DLS data affirm the formation of amorphous P and crystalline F nanoparticles. PVC-F nanocomposites provide thermal stability; however, PVC-P specimens have a lower thermal profile due to plasticization. The results of the migration test indicate the stability of the proposed composites in different media. The surface hardness increased by adding more percentages of F nanofiller, by 28.6%, for PVC-F30; however, the addition of P decreased the hardness owing to the smooth plasticized surface. All concentrations of PVC-F nanocomposites promoted sharply the tensile strength of PVC; they also increased the elastic modulus by 82%. In addition, the PVC-P composites succeeded in increasing the strain to 46%. The proposed composite was applied as water pipes for the first time without failure, compared to neat recycled PVC. The given data approves the successful grafting of recycled PVC with waste-based polyester plasticizer and green carbonate nanofiller. | ||||
