A marine biologist told us about a study some time ago. The results were clear: with every wash, tiny plastic fibers from our textiles find their way from washing machines into the wastewater, polluting rivers, lakes, oceans, and soils on an unimaginable scale. We set out on a mission to stop microplastics from ending up in our environment. The Guppyfriend Washing Bag is the first step. It makes the microplastic problem visible, communicates it, and makes it tangible for every household. It is an easy-to-use and practical solution, allowing everyone to do their bit to protect nature. Based on our own research and development experience, and through scientific findings from our cooperation with universities, research groups, industry partners, and independent laboratories, we develop ideas, initial prototypes, and - in the best cases - effective solutions against microplastic pollution. With the sales of the Guppyfriend Washing Bags, we support the non-profit organization STOP! Micro Waste. We need to know and understand the causes and consequences of microplastic pollution to be able to solve the problem.
