According to Straits Research, the global commercial seaweed market, valued at $21.8 billion in 2025, is projected to grow from $23.8 billion in 2026 to $48.6 billion by 2034, at a CAGR of 9.3% from 2026–2034.
Commercial seaweed and marine macroalgae cultivated and harvested for diverse uses underpin a range of applications, including food & beverages, animal feed, agriculture & fertilizers, pharmaceuticals & nutraceuticals, cosmetics & personal care, and biofuels & industrial uses. Seaweed’s role as a sustainable, plant-based raw material supports its increasing adoption in both traditional and emerging industries worldwide.
The commercial seaweed market is being propelled by rising demand for sustainable and plant-based ingredients across processed foods, natural additives, and functional products. Seaweed is widely used to extract hydrocolloids such as agar, carrageenan, and alginates, key functional ingredients in food processing and personal care formulations. Additionally, seaweed-derived biofertilizers and biostimulants are increasingly adopted in modern agriculture to improve crop yield and resilience, backed by public policy encouraging reduced chemical fertilizer usage. Environmental applications and expanding use in high-value sectors such as nutraceuticals and sustainable industrial materials further support long-term market expansion, even as environmental regulations and marine conditions remain a consideration.
Asia-Pacific dominated the global commercial seaweed market in 2025, supported by well-established seaweed aquaculture, favorable coastal conditions, and extensive utilization of seaweed across food and industrial sectors. North America is expected to witness the fastest growth during the forecast period due to rising demand for sustainable ingredients, increasing investments in marine biotechnology, and expanding applications in agriculture, food processing, and personal care products.
