Circular recycling of polyester and polyurethane blended textile waste
The aim of this project was to develop and evaluate a circular method for recycling of polyester and polyurethane blended textile waste. The aim was to regenerate polyester and polyurethane to promote a non-toxic environment and realize resource-efficient production of sustainable materials for the textile industry.
In this project, polyester and polyurethane were chemically separated from a blended waste stream. Elastane was chosen as the model polyurethane, and focus was on simultanous recovery of polyol from elastane and monomer from polyester.
As an integral part of the project, in alignment with the Swedish government’s aim for a non-toxic environment, chemical risks were assessed alongside other environmental issues like climate change potential for different recycling scenarios. The environmental benefits and costs associated with the implementation of this recycling process was examined through LCA.
