A UK firm that makes packaging from seaweed has been named as one of the £1m winners of Prince William's Earthshot climate prize.
The alternative to plastic was developed by London startup Notpla.
The firm was founded by Rodrigo Garcia Gonzalez and Pierre Paslier while they were students at Imperial College London and the Royal College of Art.
The Earthshot Prize gives grants to firms that innovative ideas for the environment that can be scaled-up.
Hackney-based Notpla first developed an edible "bubble" called an "Ooho" that could hold water, and then a plastic alternative called "Notpla" made from seaweed.
