AI Technical Summary
Technical Problem
Current methods for recycling fiber blends, such as polycotton, are energy-intensive, use toxic solvents, and are not suitable for all blend ratios, limiting industrial implementation and posing environmental risks.
Method used
A microwave-assisted chemical recycling process using a 'green' solvent to separate fiber blends without solubilization, allowing for rapid and efficient recovery of components like PET, cotton, nylon, and elastane from mixed textiles.
Benefits of technology
The method is fast, energy-efficient, and environmentally friendly, achieving high recovery yields of fiber components with minimal environmental impact, suitable for a wide range of blend ratios and types.
