Are your clothes dirty? That’s a questions I asked myself when I learned about the EU’s new ban on imports of clothes and textiles that contain nonylphenol ethoxylates, also known as NPEs. I’ve written quite a bit about fast fashion–as well as the push for supply chain transparency through #FashionRevolution, and supporting fashion recycling through the #ShopDropChallenge. But I never really knew much about the connection between fast fashion, NPEs and the environment. Until now.
