New Research Analyses Pathways for PET and Other Chemicals from Textile Recycling
- Tuesday, 26 February 2019
Textile waste recycling is frequently hindered by dyes and other finishing agents which may be present, so preparation (by grinding, decolouration, etc.) is an important step for efficient recycling. While distinctions have traditionally been made between chemical and mechanical recycling, recent findings by RESYNTEX have moved the project closer to demonstrating a complete reprocessing line for the biochemical transformation of textiles into chemicals.
A report from the University of Maribor summarises the RESYNTEX studies on environmentally-friendly processes for transforming natural and synthetic waste fibres into feedstock intermediates such as:
- Low molecular weight peptides for oil-based resin replacement
- Glucose solution for bioethanol production
- PAs oligomers/monomers for the synthesis of value-added chemicals
- Terephthalic acid for PET bottle production
The research also studied the treatment of residual liquid and solid waste resulting from the process. The integration of these results informed the selection of promising chemical and enzymatic degradation routes for the overall RESYNTEX process, with optimised recipes and experimental protocols.
