Ingenious upcycling turns discarded medical device into water filter

Every year across the world, more than 250 million dialysis filters are thrown away after only a single use cleansing a kidney patient’s blood of toxins. What if those filters could be recycled for a new use, wondered Tel Aviv University Faculty of Medicine Prof. Yoram Lass.

Lass, whose specialty is in hemodynamics (the dynamics of blood flow) developed a novel patent for cleaning water using dialysis filters. Not only would the quality far surpass existing industrial purification systems, but the raw materials – those millions of discarded filters piling up in landfills – were essentially free for the cost of pick-up and delivery.

NUFiltration’s repurposed dialysis filters are currently used in three industries. The most groundbreaking is purifying water in hard-to-reach rural areas of developing nations. NUFiltration packages multiple filters into a hand-carried machine that costs less than $1,000.

The unit can take water from a polluted source such a river and purify up to 500 liters an hour – “enough to supply all the daily water needs of 300 to 400 people who didn’t have access before,”. Read more>>>
