Selective Nylon Separation and Regeneration

This innovative system uses a unique, non-toxic solvent to selectively dissolve nylon from blended textile waste. Unlike existing recycling processes, this low-energy, eco-friendly approach supports sustainability and exemplifies a circular economy by reducing waste and conserving resources.

Application	Separating and recovering nylon offers an alternative to virgin nylon fibre and a new recycling method of post-consumer garment made of nylon.
Industry Benefit	The new development to separate and recover nylon would raise the recycling rate of nylon, which is as low as 1.9% in the recycling market due to technical challenges and low cost for producing new nylon.
Technological Breakthrough	Currently, there is no commercial solution to address the separation and regeneration of nylon at a low-cost and eco-friendly level. Existing process often utilise strong chemicals and energy without selectively separate nylon from the collected waste. The focus of this project covers the separation and regeneration of nylon from textile waste, while existing nylon recycling process mainly focuses no selectively recycling, depolymerisation nylon waste, then repolymerisation, and recycling fishing net.
