Commercial Seaweed Market to Hit USD 15.40 Billion by 2035, Driven by Expanding Applications Across Food and Agriculture

Rising consumer awareness of sustainable and plant-based products is fueling the expansion of the Commercial Seaweed Market globally.

NEWARK, DE, UNITED STATES, May 15, 2025 /EINPresswire.com/ -- The global commercial seaweed market is poised for steady expansion, with an estimated valuation of USD 12.03 billion in 2025 and projected to reach USD 15.40 billion by 2035, growing at a CAGR of 2.5% during the forecast period. This growth is fueled by the increasing demand for seaweed-based products across diverse sectors, including food & beverages, pharmaceuticals, agriculture, personal care, and animal feed.

The market’s upward trajectory is largely driven by seaweed’s high nutritional value and associated health benefits, as well as its growing usage in the production of hydrocolloids such as alginate, carrageenan, and agar.

Brown and Red Seaweed in High Demand for Industrial Applications

Among the various types of seaweed, red and brown seaweed are witnessing high demand, especially for industrial applications. Red seaweed is widely used in producing carrageenan and agar, while brown seaweed is valued for its alginate content. These seaweed-based hydrocolloids are crucial functional ingredients used as thickeners, stabilizers, and emulsifiers in food and beverage formulations.

The business outlook for seaweed-based hydrocolloids remains positive due to rising clean label trends and the need for plant-based alternatives in food manufacturing. In addition, seaweed used in animal feed is gaining traction for its prebiotic and antimicrobial properties, promoting healthier livestock without synthetic additives.

Rising Use of Seaweed in Cosmetics, Bioplastics, and Organic Farming

The commercial seaweed market is expanding rapidly into non-food sectors. In the cosmetics industry, seaweed is prized for its anti-aging, moisturizing, and detoxifying properties. Leading beauty brands are incorporating seaweed extracts into serums, lotions, and facial masks to appeal to consumers looking for natural skincare solutions.

Furthermore, seaweed-based bioplastics are creating new opportunities within the ocean-based plant economy. These biodegradable materials offer an eco-friendly alternative to traditional petroleum-based plastics, addressing critical environmental concerns such as plastic pollution.

In agriculture, seaweed-derived products such as seaweed-based fertilizers are used to enhance soil fertility, improve crop yield, and support organic farming practices. These products are especially in demand as farmers shift toward regenerative agriculture to combat the effects of climate change and soil degradation.

Climate Change and Technological Innovation Influencing Market Dynamics

The seaweed industry is also being shaped by climate change and its impact on ocean ecosystems. As rising temperatures and ocean acidification affect marine biodiversity, there is increased urgency to adopt sustainable aquaculture trends and innovative seaweed farming technologies.
To address these challenges, stakeholders are investing in research and development to improve the seaweed value chain, from seedling production and ocean farming to processing and global distribution. Comparison of seaweed farming technologies by country reveals significant investment in vertical farming systems, automated harvesting, and sensor-based monitoring tools.

Regulatory Support and Investment Bolstering Market Expansion

The regulatory landscape for seaweed exports is evolving rapidly, with several countries streamlining export policies and providing incentives for sustainable aquaculture. Public and private sector investments are also increasing, with a focus on building resilient supply chains and exploring marine algae's commercial potential in new product categories.

Stakeholders across the globe are recognizing the potential of commercial seaweed in pharmaceuticals and nutraceuticals, with clinical research exploring its antioxidant, anti-inflammatory, and antimicrobial properties. These developments are expected to open new revenue streams for producers and processors alike.
