Selective Separation and Recovery of Nylon from Textile Waste

Current recycling methods struggle to separate nylon from blends, and rely on expensive processes that involve high temparature and harsh solvents.

• The system enables 99.8% solvent reuse. As the process operating at ambient temperature and pressure, it requires significantly less energy.
• The technology prevents damage to nylon’s molecular chains. The recovered nylon exhibits a tensile strength exceeding 400 MPa, making them suitable for sportswear production without the addition of virgin nylon.
• This method not only separates nylon but also preserves the integrity of the other components, enabling comprehensive recycling of blended textiles.

• A life cycle analysis of this technology shows that the data reveal significant improvements across several key indicators.
• By avoiding the use of harsh chemical treatments that endanger human health and the environment, the technology reduces health risks by over 90% and environmental damage by 80% compared to traditional methods.
• The recycling of nylon waste reduces reliance on crude oil and decreases natural resource depletion by 40%.
