Seaweed is the collective name given to the plethora of species of macroscopic, multicellular marine algae present in the world’s oceans. The broad categorization is based on color, and they are segmented as red, brown, and green algae.
Commercial seaweed has many applications in human food, pharmaceutical production, cosmetics, animal feed, agricultural production, alternative fuel sources, and management of waste, among others. The figures in recent years show that Indonesia is the world’s largest seaweed producer, with the Philippines coming in second. In more specific applications, alginates are commonly used in wound dressings and the production of dental molds in the medical field. Also, applications in microbiology research are found for agar, a plant-based goo similar to gelatin and made from seaweed, which is extensively used as a culture medium.
The growth of the commercial seaweed market is mainly driven by an increase in investments from several multinational manufacturers, and extensive R&D initiatives have been taken to explore the applications of seaweeds in several fields. Seaweeds are also used on a large scale for human consumption due to their high nutritive value, and applications of seaweed in Chinese, Japanese, and Korean cuisines are quite popular, providing additional impetus for market growth. As for the restraints of the market, the high costs, as well as the fact that the market remains a specialty sector, are the main problems faced by the industry.
