Seaweed or macroalgae refers to several species of macroscopic, multicellular, marine algae.

The term includes some types of red, brown, and green macroalgae. Seaweed may provide excellent opportunities for its industrial exploitation as they could be a source of multiple compounds (i.e. polysaccharides, proteins and phenols) with applications such as food [2][3] and animal feed,[3] pharmaceuticals [4] or fertilizers.
There are various applications of commercial seaweeds, such as human food, animal feed, agriculture, and others which include cosmetics, integrated aquaculture, biomass as biofuel, and wastewater management. Seaweeds are used on a large scale for human consumption due to their high nutritive value and usage of raw seaweeds in Chinese, Japanese, and Korean cuisines.

The global Commercial Seaweeds market was valued at 17000 million US$ in 2018 and will reach 33600 million US$ by the end of 2025, growing at a CAGR of 8.9% during 2019-2025.
