Growth Factors in the Seaweed Market

·      Expanding Opportunities for Plant-Based Offerings 

Increasing preferences for plant-based diets and sustainable ingredients are significant drivers of growth in the global seaweed market. Nutritionally, seaweed is a rich source of iodine, vitamins, and antioxidants, making it popular among health-conscious consumers. It is now being incorporated into snacks and seasonings, as well as into plant-based burgers. One such example is Akua, a food startup that developed kelp-based burgers as a sustainable alternative to meat and even more resource-efficient than traditional plant-based options. The opportunities within the food and beverage sector for seaweed are tremendous, especially since over 76% of the market revenue share comes from human consumption. Initiatives like India’s $86.8 million Blue Revolution Scheme also supports increasing seaweed production to help meet this demand. Seaweed continues to gain traction, especially in North America and Europe, alongside the rising popularity of vegan and vegetarian diets.

·      Growing Uses Across Multiple Sectors 

The food industry is not the only sector poised to benefit from seaweed. It is also gaining traction in agriculture, pharmaceuticals, and cosmetics, where it is used in Algotherm creams and serums for its antioxidant properties. Moreover, Algaia’s seaweed-based biostimulants are improving soil health and crop productivity in agriculture. There is an increasing natural ingredient demand, offering growth potential in the seaweed extracts market, currently valued at $16.5 billion. Cargill is another company supporting the enlargement of the market by investing in seaweed-deriving products like the WavePure ADG 8250 intended for the dairy industry. Consequently, the need for seaweed is growing, prompting governments from China to fund and amend policies for sustainable production to support these emerging industries.

·      Government Support and Sustainability Focus

Global governments are advocating for seaweed farming as a sustainable market opportunity. For example, China's National Fisheries and Aquaculture Authority subsidized and reserved coastal regions for seaweed farming with the intent of fostering environmentally friendly development. Marine weeds, for their part, capture carbon and promote biological diversity, making them the darlings of green initiatives. The World Bank notes that seaweed aquaculture has the potential to create $11.8 billion in new market value through supporting nine of the UN Sustainable Development Goals. In India, initiatives such as the Blue Revolution are aiming to scale production to 1 million metric tons per year. The combination of sustainability focus, alongside the increased funding aimed towards improving farming technology, is making marine algae a favored target for eco-conscious markets and investors.

Key Trends in the Seaweed Market

·      Recent Developments in Biofuels From Seaweed 

With the enduring quest for clean energy options, seaweed has emerged as a valuable candidate for biofuel production. In comparison to land-based biofuel crops, seaweed has several advantages as it grows much faster, does not require fresh water, and contains significant amounts of oil which can be converted into biodiesel. Research shows that the eicosapentaenoic acid found in seaweed can make up to 50% of its fatty acid content. Investment is being poured into biorefinery technology to improve the efficiency of biofuels harvesting. Startups such as Oceanium are leading these initiatives. Governments are supporting the growth of the seaweed industry as well, with China having policies dating back to the 1950s which promoted the use of seaweed for energy purposes. As oil prices increase, coupled with more stringent eco-regulations, the seaweed biofuels industry is starting to flourish. These biofuels provide a sustainable option and do not compete for land or resources with food crops.

·      Advances in Eco-Friendly Packaging 

The plastic ban is resulting in the seaweed industry experiencing a new wave of growth in sustainable packaging alternatives. Solutions to the sea plastic crisis like Oceanium’s seaweed based bioplastics which are both biodegradable and safe for the oceans are beginning to enter the market. These bioplastics are derived from cultivated seaweed, a resource that is renewable and sustainable. Advanced processing technology to produce alginate based materials is being used by brands like FMC Corporation, thus aiding in the growth of seaweed’s market potential in packaging. This is in line with consumers expectations as 98% of all seaweed production meets sustainable aquaculture standards. Improvements in the techniques of extracting and drying these materials are making it easier for manufacturers to scale their production, while the natural gelling ability of seaweed is allowing brands to produce durable, low impact packaging which is attracting major industrial attention.

·      Introduction to Functional Foods and Nutraceuticals 

The increasing consumption of seaweed in contries like the US and Canada spanning a wide range of functional foods and nutraceuticals is largely because of its dense nutritive profile. Supply of Seaweed snacks and supplements are booming as the demand for gut health increases. As an example, SeaSnax continues to manufacture organic seaweed flakes which aim to serve as low sodium, mineral-rich snacks. There is also a rapidly growing market for powdered seaweed which is often used in health supplements because of its long shelf life. Companies such as The Seaweeds Company are tapping into the plant based diet craze by developing seaweed-derived proteins for vegan diets. There is a clear spike in demand for seaweed in functional foods all over North America and the US market leads the pack with its rich iodine and antioxidant content making it a star in the health and wellness space.
