In the last ten years, cultivated seaweed production has increased by approximately 50%. The global seaweed processing industry is estimated to use 10 to 12 million tonnes of seaweed per year (frozen weight). With the growing popularity of seaweed consumption, sea plant cultivation is expected to increase. The global commercial seaweed market is expected to grow to $24.92 billion in 2028, up from $15.01 billion in 2021.
