Assessment of the presence of hazardous components in textile wastes

Original language description

Providing products for people’s comfort, the textile industry is of global importance. However, the textile value chain is long and complex with various process steps involving large quantities of different chemicals. Although these compounds are necessary for the raw material production, the production of fibers, the wet treatment, and the finishing steps, many of them have toxic and ecotoxic effects not only during the production step, but also at the end of the life cycle in a landfill. Among the most problematic substances are dyes and pigments, most of which are made up of synthetic organic compounds and contain heavy metals. Both waste water and landfill leachate contain water-soluble heavy metal ions and compounds that can be characterized by their high persistence and bioaccumulation in the environment. Another hazardous group are per- and polyfluorinated alkyl substances (PFASs). These synthetic compounds with at least one fluorinatedcarbon have excellent hydrophobicity and oleophobicity properties and are therefore widely used in textile products as a part of repelling agents. Sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) are the most commonly detected PFASs. Both of these compounds are toxic, persistent and highly bio-accumulative. Textile waste containing heavy metals and PFASs will remain in a landfill for years, and the leachate will be subsequently contaminated. A major research gap at present is the analysis of toxic compounds in textile waste. Therefore, the aim of our key research will be the identification of potentially toxic compounds in textile waste by laboratory tests. Toxic contaminant characterisation will be determined based on leaching test results, specifically using the percolating leaching test as an advanced waste characterisation test that simulates the geochemical behaviour of textile waste under real conditions. Experiments will be performed on real textile waste samples provided by partners. Obtained leachates will be analysed to quantitatively and qualitatively characterise textile waste contaminants. The results will be discussed with a view to the elimination of the quantity and the negative impact of the textile waste on the environment.
