A new dimension for the future of radiology, being more sustainable and providing a basis for circular raw materials like gadolinium and iodine. There’s growing concern about the huge amounts of contrast media in our precious water and environment. It is very efficient to remove these substances directly at the source. Zereau’s technology provides new perspectives for a cleaner environment in combination with harvesting scarce raw materials out of patient’s excreta. Scaling up this initiative is on the horizon.
