Microfibers released from washing harm the environment. With each wash, countless plastic fibers from synthetic textiles are making their way from washing machines into rivers and oceans.


STOP! Micro Waste is a nonprofit initiative and is dedicated to raise awareness about the (micro)plastic problem. We aim to explore and initiate great ideas on how to avoid, replace and re-use plastics in every day life and beyond.
