| Abstract(E) | Automotive plastic waste components typically contain various solid contaminants, including insert metals, rubber hoses, gaskets, and reinforcing materials such as glass fibers embedded within the resin matrix. These heterogeneous inclusions significantly hinder the recovery of high-purity resin through conventional mechanical separation techniques, which are often ineffective in isolating the resin from non-resin materials. To address this issue, we have developed a chemical sorting technology that enables selective dissolution of the target resin while efficiently removing contaminants. This process involves the use of solvents to dissolve the resin, followed by filtration and centrifugal separation to eliminate solid impurities. As a result, the method achieves a substantially higher separation purity compared to traditional approaches. Furthermore, the system is designed to accommodate complex composite waste and supports continuous processing, making it suitable for industrial-scale recycling operations. This technological advancement enables the high-quality recovery of resins derived from end-of-life vehicles and contributes to the realization of a sustainable circular economy in the automotive sector. |
