PFAS-coated clothes that are thrown away will often end up either incinerated or in landfill. Unless incinerated at very high temperatures (>1000oC), fluorinated polymers could release more harmful PFAS during burning. PFAS of environmental concern have also been found in landfill leachate. PFAS is found in treated waste water from industrial and domestic sources and has been found in both rivers and groundwater. Conventional drinking water processes will not remove PFAS.Small quantities of PFAS will be removed during wash and wear of products containing PFAS. This includes fluorinated polymers used on stain-resistant coatings, and non-polymers that remain on clothes after production (Lassen et al. 2015).Non-polymer PFAS can build up in blood protein of animals, and is not always removed quickly. This means that predators eating PFAS-contaminated food will have higher levels in their bloodstream, and concentrations can increase up the food chain. Studies suggest that build up of PFAS is similar to those of other Persistent Organic Pollutants such as DDT.PFAS are estimated to be settling in arctic regions at rates of tens to hundreds of kilograms per year (25-850kg per year), depending on the specific PFAS chemical in question. Certain PFAS are released as gases to the environment and are blown a long way by wind and air currents in the atmosphere,. These gas PFAS will over time degrade to more persistent chemicals like PFOS and PFOA. This may be one reason why PFAS of environmental concern have been found in remote regions such as the Arctic as well as near PFAS production sitesPFAS including PFOS and PFOA have been found in air samples around Europe. The chemicals are found in small quantities, but appear in almost all samples tested. PFAS enters the atmosphere both from factories and the air inside our homes. https://www.ncbi.nlm.nih.gov/pubmed/17554424 Non-polymer PFAS are used in the production of fluorinated polymers. The manufacture of stain-resistant finishes generally releases these PFASs into the environment, both by air and water emissions. They are very hard to remove during water treatment. Workers in textiles factories are some of the population most exposed to these potentially harmful chemicals.

RFID for transparency, traceability and end-of-life handling for textiles

An investigation into RFID technology as a possible solution to improve processing efficiency of discarded textiles and garments.

To investigate possible solutions for efficient handling of the increasing amounts of textiles and garments being discarded each year, this project was granted funding from Vinnova under the call Innovationer för ett Hållbart Samhälle 2018. The project was finalised on the 30th of June 2021 and the consortium comprised some 20 companies, which represented many businesses within the range from research and development,textile and fashion,sorting and recycling, charity and second-hand, trimmings and smart labelling through standardisation.

The main objectives were to investigate and build knowledge regarding the possibilities to utilise a digital information system,adapted for the textile and fashion industry,based on RFID technology,where information availability,transparency and traceability would be crucial to enable and facilitate handling of textiles at their end-of-life.
