Global Seaweed New and Emerging Markets Report Summary (2023)

Core Content

The Global Seaweed New and Emerging Markets Report 2023 explores the potential of seaweed beyond traditional markets, such as food and hydrocolloids, and highlights ten new applications with significant growth opportunities. The report emphasizes the environmental, socioeconomic, and commercial benefits of seaweed farming and its potential to contribute to global sustainability goals.

Main Points

1. Introduction

• Seaweed has been cultivated for decades, primarily in Asia, but there is growing interest in expanding its production and use to new regions and applications.
• Seaweed farming offers multiple benefits, including:
  • Carbon sequestration
  • Marine biodiversity support
  • Socioeconomic development, especially in coastal communities
  • Environmental benefits through bioremediation and methane reduction
• Current seaweed markets are dominated by Asian countries, which account for over 98% of global farmed seaweed production.

2. Methodology

• The report is based on interviews with stakeholders, scientific literature, and market data.
• It uses a three-phase approach:
  • Phase 1: Identification of relevant industry sectors
  • Phase 2: Deep dives into selected applications
  • Phase 3: Market forecast exercise
• Limitations include data accuracy, supply chain consistency, and regulatory challenges.

3. Commonities of Emerging Market Opportunities

• Seaweed is considered a third-generation feedstock with potential to replace fossil fuels and synthetic products.
• Common challenges across all markets:
  • Limited supply and quality of seaweed
  • High production and processing costs
  • Regulatory barriers
  • Lack of awareness and standardization

4. Market Sectors

• Biostimulants: Projected to reach $4.4 billion by 2030. They offer competitive value propositions and are relatively easy to scale.
• Animal Feed Additives: Help reduce feed conversion ratios and dependence on synthetic products.
• Pet Food: Growing market with potential for niche applications.
• Methane-Reducing Feed Supplements: A novel market with promising but challenging development.
• Nutraceuticals: High-value but face regulatory and functional challenges.
• Alternative Proteins: May provide sustainable protein sources but need cost and availability improvements.
• Fabrics: Potential for seaweed-based textiles, such as lyocell and alginate-based materials.
• Bioplastics: Substitutes for conventional plastics, with potential for biodegradable and non-biodegradable variants.
• Pharmaceuticals: Long-term opportunity but with high development costs and regulatory hurdles.
• Construction: May offer niche applications, such as insulation materials and waste valorization.

5. Ecosystem Services

• Seaweed can provide ecosystem services such as:
  • Blue Carbon: Seaweed can sequester carbon, with potential for carbon credit certification by 2025.
  • Bioremediation: Ability to remove pollutants and toxins from soil and water.
  • Methane Reduction: Additives in animal feed can reduce methane emissions.
  • Biodiversity and Habitat Provisioning: Seaweed farming can support marine biodiversity.
• Challenges include:
  • Lack of standardized monitoring, reporting, and verification
  • Slow certification processes
  • Limited awareness and alignment between scientific and commercial communities

6. Conclusion

• The report outlines three market timelines:
  • Short-term (before 2025): Biostimulants, animal feed additives, pet food, and methane-reducing supplements
  • Medium-term (2024–2028): Nutraceuticals, alternative proteins, bioplastics, and fabrics
  • Long-term (after 2028): Pharmaceuticals and construction
• Seaweed farming can contribute to at least nine of the 17 UN Sustainable Development Goals (SDGs), including poverty reduction, climate action, and environmental sustainability.
• To realize its full potential, the industry must:
  • Improve supply chain consistency and volume
  • Reduce production and processing costs
  • Address regulatory barriers
  • Develop biorefinery systems for multi-product utilization
  • Enhance awareness and alignment between science and industry

Key Information

• Global Seaweed Production (2020): 36 million tons wet weight, with most coming from Saccharina, Eucheumatoid, Gracilaria, Pyropia, and Undaria species.
• Top Producers: China (56%), Indonesia (27%), South Korea (4%), Philippines (4%), and other Asian countries.
• Western Perspective: Seaweed farming is gaining traction in North America and Europe, with the EU promoting it as a key component of its blue bioeconomy strategy.
• Market Potential: Seaweed-based products are expected to grow significantly, with some sectors like biostimulants and animal feed additives already showing strong value propositions.
• Ecosystem Services: Seaweed can be used to mitigate climate change, support biodiversity, and provide environmental benefits through carbon sequestration and bioremediation.

Summary of Findings

• Finding 1: The most promising short-term markets are biostimulants, animal feed additives, pet food, and methane-reducing supplements.
• Finding 2: Medium-term opportunities include nutraceuticals, alternative proteins, bioplastics, and fabrics, which require cost and availability improvements.
• Finding 3: Long-term opportunities are in pharmaceuticals and construction, but these markets are still in early development stages.
• Finding 4: The industry faces significant challenges, including limited supply, high costs, and regulatory hurdles.
• Finding 5: The environmental benefits of seaweed farming are a major driver for its growth, especially as demand for "green" products increases.
• Finding 6: Ecosystem services such as blue carbon and bioremediation can boost green economic growth, but require robust monitoring and certification.

Future Outlook

• The report predicts that the seaweed market will reach $11.8 billion by 2030 (Figure A).
• Biorefineries offer a pathway to more efficient and economically viable processing.
• Regulatory frameworks will play a crucial role in shaping the future of these markets.
• Innovation is needed in non-Asian regions to avoid reliance on the Asian model and to develop new applications and markets.

Additional Notes

• Data Limitations: Reported production volumes in some Asian countries may not reflect actual levels due to data reporting issues.
• Innovation Gap: There is a lack of new cultivation and processing methods in traditional seaweed-producing regions.
• Sustainability: Seaweed farming has the potential to support sustainable development and environmental regeneration, especially in fragile coastal communities.
