Closed-loop recycling of wool/synthetic blend textiles into high-end textile fibres

Reference number
Coordinator RISE Research Institutes of Sweden AB
Funding from Vinnova SEK 2 886 953
Project duration November 2021 - November 2025
Status Ongoing
Venture Circular and biobased economy
Call Increased resource efficiency for a circular industry

Purpose and goal

By developing technical methods for 1) chemical separation and recycling of textile material blends containing both wool and synthetic fibres, and 2) fibre spinning using the recycled wool and synthetic materials this project aims to increase the circular use of materials in textile industry.

Expected results and effects

The expected outcomes from this project are new technical methods for chemical recycling of blend textiles and fiber spinning of recycled textile materials. These methods are expected to lead to an increased use of recycled raw materials in the textile industry and increased incentives for the collection of both production waste and used textiles, which in turn contributes to an increased resource efficiency and a reduced dependence on finite resources such as oil.

Planned approach and implementation

This project will start with a practical survey of the available raw materials, i.e. waste and recycled textiles, collected by industrial partners. With a continued focus on the most common wool / synthetic blends, experiments are then carried out to separate wool and synthetic fibers, and spin each component into new fibers using processes for both wet spinning and melt spinning. The project also includes developing a business plan for future upscaling and implementation of the technology.
