Hydrothermal Processing: This method uses supercritical water to break down composite materials into their basic components. Recent research has focused on optimizing the process to increase yield and reduce energy consumption.Emerging Technologies in Composite RecyclingBeyond mechanical and chemical recycling, several emerging technologies show promise in overcoming the challenges of composite recycling:1. Microwave-Assisted Recycling: Microwave-assisted recycling is an innovative technique that uses microwave radiation to selectively heat and break down the polymer matrix in composite materials, allowing for the recovery of reinforcing fibers such as carbon or glass with minimal damage. The process leverages the unique interaction of microwaves with different materials, targeting the polymer matrix while leaving the fibers largely unaffected. As the matrix heats and decomposes, the fibers can be extracted in good condition, retaining their structural properties for reuse. This method is energy-efficient compared to traditional thermal processes and has a lower environmental impact due to the selective heating of the matrix. However, challenges remain in scaling up this technology for industrial use and in fine-tuning the process for different types of composites.%u0130novasyon ve Kompozit / Innovation and Composite
