US-based startup Sway aims to create thin film alternatives from seaweed to replace everyday single-use plastics, such as polybags, retail bags and wrappers, which regenerate rather than damage the planet. Helmed by designer Julia Marsh, the concept adheres to the circular premises we champion on this platform. There is no proof of concept yet, but the company is launching a trial, which could see it replace between 1,000 and 300,000 retail and polybags across CVS, Walmart and Target. Watch this space.
