A human-scale solution to microfiber pollution: The Cora Ball
by Rozalia Project (Non-governmental organization (NGO))
Our clothes are breaking up into tiny, tiny pieces in our washing machines and washing out the drain water into our public waterways. Once in our rivers, lakes and ocean; these tiny pieces of plastic and processed, dyed natural fibers are eaten by creatures of all sizes. Those creatures are harmed and poisoned by this pollution. What they eat, we eat. The problem of microfiber is one of the areas Rozalia Project is focusing our efforts through innovation and impact in the form of a human-scale, consumer-based solution.

Our Solution: The Cora Ball is a microfiber catching laundry ball. It works in all types of washing machines, is easy to use and easy to clean. It was inspired by nature; coral and sea anemones, creatures who pick small things out of flowing water. That is what the Cora Ball does, it allows water to flow and your clothes to get clean, but catches those little pieces of plastic and fibers before they can flow into our public waterways. As a bonus, it does a great job collecting hair - people and pet hair!

How the Cora Ball works: You just drop it into your washing machine. The principle of the Cora Balls effectiveness is mechanical - the fibers get stuck on the coral-like stalks. Then, the fibers (and hair) on the stalks helps trap more fibers and hair! When the load is done, and depending on what clothes you washed, you will see what look like hairballs in the Cora Ball - they are really microfiber and hair tangled together. You can clean the Cora Ball like you clean a hairbrush - not needed after every wash, but when you see it start to fill up. In addition, our intent is to develop a collection/take back system and find an opportunity to upcycle the fibers.

Our commitment is to bring the Cora ball into the world and as many washing machines as possible and to spread the word about the problem of microfiber pollution and in so doing, inspire innovation from the multiple industries involved (textiles - home textiles and the clothing industry, white goods, wastewater treatment) as well as remind people that their washing machines are a land-sea interface and what goes down the drain can end up in our public waterways. We will give everyone who wears and washes clothes an opportunity to be part of the solution to microfiber pollution and protect our ocean, lakes and rivers.
