The global seaweed cultivation market, valued at USD 22 billion in 2025, is projected to grow at a CAGR of 13.7%, reaching USD 69.5 billion by 2034. Demand for sustainable, nutrient-rich resources in industries like food, pharmaceuticals, and cosmetics fuels growth. Key regions include Asia-Pacific, Europe, and North America.
Seaweed Cultivation Market
Dublin, June 16, 2025 (GLOBE NEWSWIRE) -- The "Seaweed Cultivation Market Size, Share, Trends, Analysis, and Forecast 2025-2034 | Global Industry Growth, Competitive Landscape, Opportunities, and Challenges" has been added to ResearchAndMarkets.com's offering.
The global seaweed cultivation market, currently valued at USD 22 billion, is projected to achieve a compound annual growth rate (CAGR) of 13.7%, reaching USD 69.5 billion by 2034
This growth reflects a global shift toward sustainable, nutrient-rich, and environmentally friendly resources across multiple sectors. Seaweed, highly versatile and not dependent on traditional resources such as arable land and freshwater, offers significant benefits as it contributes to industries like food, pharmaceuticals, cosmetics, animal feed, and biofuels.
Asia-Pacific dominates global seaweed production, with China, Indonesia, and South Korea leading efforts. However, Europe and North America are rapidly catching up, recognizing seaweed's environmental benefits, including carbon sequestration and water purification. Increasing consumer awareness of seaweed's nutritional benefits, rich in iodine, protein, vitamins, and antioxidants, is bolstering its popularity in plant-based diets. In response, both governments and private sectors are investing heavily in research and sustainable farming practices to support this burgeoning market.
Technological advancements, like offshore cultivation systems and integrated multi-trophic aquaculture (IMTA), are enhancing yield efficiency and sustainability. The consumption of food-grade seaweed has surged across North America and Europe, driven by vegan and functional food products. Concurrently, seaweed extracts are increasingly used in biofertilizers and cosmetics. The biofuel sector is also exploring macroalgae for renewable energy, though large-scale commercial viability is still evolving.
Regulatory support is growing with new policies, grants, and marine spatial planning initiatives to promote aquaculture. Public-private partnerships focus on training and technology transfer, strengthening seaweed's role in economic development. As we approach 2025, seaweed's significance in carbon offsetting and environmental remediation is expected to draw investments from climate-driven funds and carbon credit markets.
Looking forward, research into high-value seaweed varieties for use in pharmaceuticals, nutraceuticals, and bioplastics will intensify. Developments in seaweed-based packaging materials and biodegradable polymers will address rising anti-plastic legislation. Vertical integration across supply chains will boost quality control and profitability, while advancements in remote sensing and AI will optimize cultivation practices.
Africa and Latin America, with their vast coastlines, are emerging as new growth frontiers in seaweed cultivation. As consumer consciousness, environmental policies, and technology converge, the market is poised to become an essential element of the circular economy and sustainable marine industries worldwide.

A Canadian Auto Union Leader Realized Media, Communication Important
Buzz Hargrove, former president of the Canadian Auto Workers union Over the weekend, Basil 'Buzz' Hargrove, 81, died. He was the president of the Canadian Auto Workers union from 1992 to 2008. His passing was announced by Unifor, the successor organization to the CAW. The CAW originally was part of the Detroit-based United Auto Workers union. The Canadian union broke away after disagreements with the Detroit union. Hargrove struck a much different done than the UAW. Buzz Hargrove embraced being a public figure. By the 1980s, UAW chiefs were much more low key. Some UAW chiefs, such as Steve Yokich (1994 to 2002) and Ron Gettelfinger (2002 to 2010) were openly hostile to journalists. Hargrove followed a different path. In 2002 and 2005, I covered the CAW's labor talks with the Detroit-based automakers. For each round of negotiations, the Canadian union rented space at three different Toronto hotels. If a reporter could secure a room at the respective hotels, you could wander up to the CAW offices and chat with the union staff. Buzz Hargrove also viewed the press as a means to get his message out. He would come down to the press room at each hotel and conduct a press conference. More importantly, once the union reached an agreement with each automaker, the CAW viewed reporters as a way to reveal contract details prior to a ratification vote – pay, benefits, the fate of certain factories. Across the border? The UAW (at least during the Yokich and Gettelfinger eras) viewed reporters as the enemy. There were no details to be revealed about contract details until members voted. The UAW wanted complete control. There were times when Buzz Hargrove surprised those he negotiated with. In one of the talks I covered, reporters were summoned where the CAW and Ford would have a statement. Reporters were told no formal announcement was coming. Once the event started, Hargrove said an announcement had been reached. The Ford Canadian executive clearly had been caught by surprise. But what could she do? She confirmed both sides had an accord. In 2008, Hargrove's final year as CAW chief, the union leader had one last surprise. The Detroit automakers suffered from severe financial problems. The CAW had reached a new labor contract with Ford. A surprise announcement followed, ahead of negotiations with the other two members of the Detroit Three. Two years ago, the UAW went on strike against all of the Detroit automakers. Things had definitely changed. Current UAW chief Shawn Fain utilized livestreams and other methods of staying in touch with union members.
