  "abstract": "Recycling and advanced recycling technologies for many end-of-life tires (ELT) are vital for advancing circular economy strategies. With approximately 1.5 billion end-of-life tires generated worldwide each year, developing new ELT recycling methods suitable for large-scale industrial use is essential. In this study, we examine composite materials made by blending a solid-lubricant filler, such as polytetrafluoroethylene (PTFE), with at least 70% recycled waste tire material. Spark plasma sintering (SPS) was employed to ensure proper densification of the composites. The waste tire powder, produced by the water jet process (WJP), was chemically treated before mixing with PTFE. A series of composite samples was sintered with varying PTFE content, ranging from 5% to 30% by weight. Several characterization techniques, including thermogravimetric analysis (TGA), X-ray diffraction (XRD), differential scanning calorimetry (DSC), and Fourier transform infrared (FTIR) spectroscopy, were used to analyze the properties of pure PTFE and WJP ground tire rubber (GTR) powders. Subsequently, the sintered PTFE/WJP-GTR samples were assessed for thermal stability and tribological performance. The effects of PTFE content and chemical treatment on WJP-GTR powder were examined, and potential mechanisms involved are discussed according to X-ray photoelectron spectroscopy (XPS) spectra, profilometry measurements, and optical microscopy images. Overall, the results demonstrate significant improvements in thermal stability and a notable reduction of the coefficient of friction compared with pristine WJP-GTR. These findings are valuable for rubber products used in industrial machinery and manufacturing equipment that require efficient and dependable tribo-polymer systems.",
