Seaweeds are fascinating. They are rich in minerals, vitamins, and many bioactive components which have plenty of health benefits. They grow in a very sustainable way with only CO2, light, and some nutrients naturally found in the water. The global market for seaweed industry is expected to double in 2024 compared to 2015 and reach 22 bln USD. Seaweeds as raw material have a huge potential. They are used today in food, fertilizers, fish and animal feed, cosmetics, supplements, medicine, as a source of energy and even as a bio-filter for removing oil spills.
