Every winter, Briana Warner searches for scraps of seaweed from the cutting room floor, so she can spread it over her garden before putting it to bed for the season, but it’s often gone. “I work at a seaweed company, and even then it’s hard to get hold of,” the CEO of Atlantic Sea Farms says with a laugh. “The farmers take the scraps at the end of every week so they can feed it to their pigs. It’s in high demand.”
Seaweed is having its moment in the sun: Use of the marine plant is a rapidly growing trend that could aid in everything from global food security to climate change. Seaweed grows quickly, contains many vitamins and minerals, and produces up to 11 times the biomass of wheat and corn. It’s vastly underutilized despite its rapid growth rate, and recent studies reveal it could absorb as much carbon as the Amazon.
