Important results from the project
The project developed a novel wet-chemical process that separates wool/synthetic blended textiles and enables the recycling of both fractions. From the recovered wool, a new keratin-based performance fibre was produced. The main goals were achieved, and the project also created strong networks and interest for follow-up initiatives in the recycling of wool/synthetic garments in Sweden and internationally.
Expected long term effects
In the long term, the project can enable large-scale, high-value recycling of wool/synthetic garments instead of incineration. The process and keratin fibre may support future textile EPR, new circular business models, and investments in recycling infrastructure. The networks built around Swedish and international wool pave the way for pilot and demo projects.
Approach and implementation
The project followed a plan for the development of the separation process, fibre production, and environmental/market analysis in close collaboration between partners. Re-prioritizations were agreed with partners and documented in reports. The project leader changed during the project; the transition was smooth, communicated to Vinnova, and the overall schedule was largely kept.
