“…Based on Equation (2), alternatives P 1 , P 2 , P 3 , and P 4 have T Pn values of 0.81, 0.84, 0.88, and 0.89, respectively. Compared to the threshold value of 0.6 from the literature (Colom et al, 2023;Ghowsi & Jamshidi, 2023;Wang et al, 2023;Wiśniewska et al, 2022Wiśniewska et al, , 2021World Population Review, 2020), all of these alternatives are considered feasible.…”

“…In this case, I is the contribution of a single remanufacturing step to the overall process and its value is based on whether it is a unique and critical step that cannot be eliminated or one of several alternatives. These I values (in the range of 0.45−0.95) were taken from the literature (Ashby, 2012; Colom et al., 2023; Ghowsi & Jamshidi, 2023; Wang et al., 2023; Wiśniewska et al., 2022, 2021; World Population Review, 2020). Furthermore, E < 1 is the degree of ease of performing a single remanufacturing step E 1 + E 2 + …+ E S = 1 (Ashby, 2012; Colom et al., 2023; Ghowsi & Jamshidi, 2023; Wang et al., 2023; Wiśniewska et al., 2022, 2021; World Population Review, 2020).…”

“…Combining chemical processing under the action of mechanical shear enhances the degree of devulcanization, shortens the cure time, and improves the mechanical properties of the reclaimed rubber (e.g., the crosslink density and hardness) (Wang et al., 2023). In a representative process, a thermomechanical process was followed by microwave irradiation to produce devulcanized ethylene propylene diene rubber as a recycled component (Colom et al., 2023). This material had slightly poorer mechanical properties and thermal stability compared to natural rubber and styrene butadiene rubber.…”

Waste tires contain a large amount of embodied energy and useful materials that can be recovered. In an existing remanufacturing process, the waste tire components are separated, thermomechanical devulcanization is used to restore the formability of the waste rubber for recycling, and waste rubber powder is mixed with chemical agents and subjected to hot rolling and extrusion to form rubber sheet products. Here, the quadruple‐bottom‐line sustainability of this remanufacturing process was studied for the first time based on the global availability of waste tires, and four technical alternatives based on different levels of automation and order of the processing steps were evaluated. The numbers of each machine for separating the tire components and processing the rubber were optimized. Quantitative sustainability analysis was conducted to calculate the sustainability index (SI) of four remanufacturing alternatives based on the technological feasibility of each processing step. Furthermore, a quantitative–qualitative sustainability assessment was performed to weight a criteria performance matrix of the technical alternatives qualitatively to overcome the lack of experience in the field. Waste‐tire remanufacturing has final SI values of ∼0.69–0.79, which exceed literature threshold values, indicating that it is a sustainable business strategy.

Renowned for its oil, heat, and chemical resistance, fluoroelastomer rubber (FKM) also presents notable drawbacks, such as inferior low‐temperature performance. In this study, 2,2‐trifluoroethylamine (TF) and 2,4‐difluorobenzylamine (DF) were grafted onto epoxidized soybean oil (ESBO) to generate two innovative plasticizers: ESBO‐TF and ESBO‐DF that they were specifically designed to augment the low‐temperature performance of FKM. A thorough investigation into the effects of ESBO‐TF/DF on FKM/EPDM blends' properties was conducted. The study demonstrated that the integration of ESBO‐TF and ESBO‐DF enhanced the vital properties of the FKM/EPDM blends, including elongation at break, tear strength, and, significantly, low‐temperature performance. There was a noticeable decrease in the glass transition temperature (Tg), dropping by 3.54 and 2.95°C with the incorporation of 10 phr ESBO‐TF and ESBO‐DF, respectively. These respective plasticizers showed positive effects on the plasticization and compatibilization of the FKM/EPDM blends, thus proposing a novel methodology for developing new plasticizers for FKM and related blends.
