Professional clothing and PPE are not under Refashion’s management and are therefore not included in household textile and footwear recycling processes. You may however directly contact collection operators (those with self-deposit banks), sorting operators or garnett operators in France.
However, you can contact Recyclage-Textile.com, which offers tailor-made solutions for collecting and recycling workwear (minimum 25 kg): contact page. You can view their brochure attached to this article.
Alternatively you can contact the Association OREE which coordinates the FRIVEP project (Professional clothing reuse and recycling sector in France) or https://pro.refashion.fr/en/recycler/textile-footwear-industry-stakeholders.
