26 Mar 2021 --- South Korean start-up Real Water has developed a reusable bottle cap that filters out microplastics from water. The cap can be attached to standard water bottles with 10 mm openings, with a 7 mm variant to be completed in the next three months. “Since water bottle mouths are the same in universal markets, our product fits almost every bottle,” Hyeok-Jae Kwon, Real Water founder, tells PackagingInsights.
