Furthermore, the growing focus on environmental sustainability is a prominent trend in the seaweed market.

Seaweed Market Growth Drivers

Rising Government Initiatives to Boost Seaweed Cultivation

Seaweed cultivation can potentially improve the livelihoods of coastal fishing communities. Governments worldwide have implemented policies and allocated funds to bolster the seaweed industry. For instance, since 1950, the Chinese national and provincial governments have incentivized seaweed cultivation through various means such as policy support, financial assistance, allocation of onshore and offshore farming areas, and access to freshwater resources. However, starting in 2015, the Chinese national government initiated a restructuring of the seaweed industry in response to serious environmental and ecological concerns, including air and water pollution and unsustainable resource exploitation. China’s National Fisheries & Aquaculture Authority is focusing on the transition of the Chinese aquaculture industry towards a period of stable and gradual growth. The focus of the entire aquaculture sector is expected to shift from prioritizing quantity, value, and rapid expansion to emphasizing quality, safety, and sustainability.

In India, approximately 46-50 seaweed-based industries are grappling with raw material shortages. To address this issue, the Indian government allocated a fund of around USD 86.37 million in 2020 to boost seaweed cultivation domestically.

Additionally, Indonesia, a significant seaweed producer, is undertaking initiatives to modernize and develop its seaweed industry to increase export earnings and improve the livelihoods of coastal communities. The government has launched various programs aimed at providing high-quality seeds, enhancing farming techniques, and improving post-harvest and processing technologies. As a result, many small-scale fishermen in Indonesia have transitioned from fishing to seaweed farming to increase their incomes.

Moreover, since 2014, Switzerland's State Secretariat for Economic Affairs funded the SMART-Fish Indonesia program. Implemented by the United Nations Industrial Development Organization in collaboration with Indonesia's Ministry of Marine Affairs and Fisheries, the program aims to enhance the productivity of the seaweed value chain in Indonesia and boost the competitiveness of the seaweed industry.

The Scottish Government is committed to promoting sustainable aquaculture growth while ensuring the preservation of the wider marine environment. In 2014, the government introduced seaweed cultivation policies aimed at fostering employment and enhancing the economic prosperity of numerous rural communities throughout Scotland. These initiatives encompass support for the traditional aquaculture sectors and exploration of potential diversification into other species, including seaweed cultivation.

These supportive government initiatives aimed at boosting seaweed cultivation are anticipated to drive the growth of the global seaweed market in the coming years.

Rising Consumption of Seaweed-based Products Due to Their Nutrient-rich Profile

A wide variety of seaweed species are utilized in numerous food products worldwide. Traditionally, seaweeds have been staples in Asian cuisine, particularly in countries like China, Japan, and South Korea. However, in recent decades, these seaweed-based foods have gained popularity in Western nations, driven by their recognized health benefits.

In developed regions such as North America and Europe, the perceived health advantages of seaweed-based products are driving their adoption. Consumers view seaweed as a safe, fresh, protein-rich, iodine-rich, and low-calorie dietary option. Additionally, seaweed is rich in vitamins, minerals, and fibers, further enhancing its appeal. Major players in Western markets are focusing on innovating food products to cater to diverse demographics, capitalizing on the health benefits of seaweed, including its antioxidant properties, micronutrients, and fiber content. As a result, seaweed-containing food items such as snacks, noodles, and health beverages are witnessing a surge in demand worldwide.

Seaweed Market Growth Trend

Growing Focus on Environmental Sustainability

In recent decades, global awareness of environmental issues has led to the development of eco-friendly solutions to mitigate these issues. The rising environmental consciousness has caused significant shifts in consumer preferences, driving increased demand for sustainable products worldwide. Rising social and regulatory concerns for the environment have prompted a growing number of food and beverage companies to prioritize green initiatives as a key driver of strategic change.

The growing focus on environmental sustainability is driving seaweed cultivation efforts worldwide. Seaweed cultivation is generally considered sustainable, as it involves fast-growing, nutrient-rich macroalgae that absorb carbon dioxide (CO2) and release oxygen (O2). Furthermore, the growing demand for seaweed production is driven by the increasing popularity of veganism. According to Proveg International, global sales of plant-based meat products reached nearly USD 12 billion in 2019.

Seaweed Market Growth Opportunity

Growing Demand for Biofuels

The increasing demand for secure, sustainable, and clean energy sources is fueling the global demand for biofuels. Factors such as rising oil prices and government policies aimed at reducing greenhouse gas emissions have further contributed to this demand. Many countries have initiated or expanded renewable energy programs in response to these trends.

Both microalgae and macroalgae present promising biodiesel feedstock options that could eventually replace petroleum-based fuels. Seaweed, in particular, is a highly viable source of biofuels due to its numerous advantages, including high oil content, rapid growth rates, and minimal land and freshwater requirements. Unlike crops like soybeans, seaweed cultivation is faster, more space-efficient, and does not necessitate the use of freshwater or fertilizers. Furthermore, seaweed does not compete for land area, making it highly suitable for biofuel production.

Seaweed's composition, with approximately 85 to 90% water content, makes it ideal for biofuel production methods such as anaerobic digestion for biogas and fermentation for ethanol. Certain seaweed species, such as sugar kelp, have high carbohydrate and low lignin content, making them ideal for bioethanol production.

There is a rising need to decarbonize the transportation and aviation sectors, particularly in Europe, where these sectors exhibit rising greenhouse gas (GHG) and CO2 emissions. For instance, emissions from aviation have doubled since 1990. While electrification is a likely scenario for passenger cars, heavy transport, shipping, and aviation are expected to remain heavily reliant on liquid fuels for the foreseeable future. Seaweed is a sustainable bio-based feedstock for liquid transportation fuels, offering fast growth rates and requiring only CO2, sunlight, and nutrients naturally present in seawater. Seaweeds' high sugar content further enhances their suitability for advanced biofuel production.
