Seaweed-based packaging
Films, coatings and pods made from seaweed replace plastic in sauce sachets, takeaway box linings and flexible wraps, and break down naturally.
Seaweed grows fast without fresh water, fertilizer or farmland. Notpla (London), winner of the 2022 Earthshot Prize, makes seaweed coatings for takeaway boxes and edible drink pods; Sway (USA) develops seaweed-based alternatives to plastic film.
