Seaweed Extracts Market Report 2026

The seaweed extracts market size has grown strongly in recent years. It will grow from $2.58 billion in 2025 to $2.75 billion in 2026 at a compound annual growth rate (CAGR) of 6.3%. The growth in the historic period can be attributed to expansion of seaweed harvesting activities, increased use in traditional food products, growth of natural fertilizer adoption, rising interest in marine-based ingredients, availability of coastal biomass resources.

The seaweed extracts market size is expected to see strong growth in the next few years. It will grow to $3.49 billion in 2030 at a compound annual growth rate (CAGR) of 6.2%. The growth in the forecast period can be attributed to increasing demand for sustainable agriculture inputs, rising use in functional food formulations, expansion of plant-based cosmetic products, growing investments in marine biotechnology, increasing regulatory support for bio-based products. Major trends in the forecast period include increasing use of seaweed-based biostimulants, rising demand for natural food additives, growing application in organic agriculture, expansion of cosmetic-grade seaweed extracts, enhanced focus on bioactive compound extraction.

Rising demand for biofuels is expected to propel the growth of the seaweed extracts market going forward. Biofuels are renewable energy sources produced from organic materials such as plants, algae, or animal waste, serving as eco-friendly alternatives to fossil fuels. The rising demand for biofuels is driven by government policies mandating renewable fuel use to reduce greenhouse gas emissions and by technological advancements that have made production more cost-effective and sustainable. Seaweed extracts support biofuel production by providing a sustainable, high-yield feedstock rich in carbohydrates, which can be efficiently converted into bioethanol and biogas. For instance, in October 2024, according to the U.S. Energy Information Administration, biofuel production capacity in the United States grew by 7% in 2023, reaching 24 billion gallons per year by early 2024, driven primarily by a 44% surge in renewable diesel and other emerging biofuels. Therefore, rising demand for biofuels is driving the growth of the seaweed extracts market.

Leading companies in the seaweed extracts market are focusing on innovative plant-based solutions to meet the increasing demand for sustainable and eco-friendly agricultural inputs. Plant-based solutions utilize natural ingredients derived from plants, offering sustainable alternatives to synthetic or animal-based components across industries such as agriculture, cosmetics, and food. For instance, in June 2023, Cascadia Seaweed Corporation, a Canada-based manufacturer of seaweed-derived products, partnered with ReFeed Ltd., a Canada-based nutrient upcycling company, to launch its first seaweed-based biostimulant. This biostimulant, enriched with bioactive compounds from sustainably farmed seaweed, enhances plant growth, improves soil health, and boosts nutrient uptake. Its key benefit lies in reducing dependence on synthetic fertilizers, promoting environmentally responsible farming practices.

In March 2023, J. Rettenmaier & Söhne Group, a Germany-based company specializing in fiber and hydrocolloid products, acquired Algaia SA for an undisclosed amount. This acquisition aims to expand JRS Group’s portfolio in sustainable, algae-based solutions and strengthen its presence in the global market for natural, renewable ingredients. Algaia SA, a France-based company, specializes in producing seaweed extracts and hydrocolloids.
