Why KENKO?
Adult incontinence is an overlooked waste crisis in America.
The U.S. is the world's largest market for adult incontinence products — with over 25 million Americans experiencing some form of bladder leakage. As the population ages, disposable products could generate significantly more waste than baby diapers, yet the issue receives almost no public attention.
