As fast fashion dominates the clothing market, organizations collecting used garments are increasingly overwhelmed by poor-quality textiles. La Collecterie in Montreuil reports a significant rise in fast-fashion items, which are often made of low-quality materials like polyester. The increase in production, with 3.2 billion new garments sold in France in 2023, is exacerbating environmental issues, as less than 10% are recycled. Experts warn that while second-hand selling platforms are thriving, they hinder the flow of high-quality donations to charities, stressing the need for more sustainable consumption practices.
