Sustainability
Responsible Sourcing
Our sourcing strategy begins with ecosystem health before ingredient yield. Ocean Harvest Technology selects green, red, and brown seaweeds from multiple regions worldwide — a diversified approach that promotes biodiversity, reduces pressure on single species, and stabilises supply against climate and seasonal fluctuations.
Each site is assessed for environmental impact, natural regeneration, and community engagement before harvesting begins. We partner directly with trained coastal harvesters who follow selective cutting and leave-to-regrow practices, maintaining natural bed structure and ensuring habitat recovery — in line with sustainability principles outlined by the FAO Global Seaweed Report (2018) and World Bank Report "Global Seaweed - New and Emerging Markets" (2023).
This diversified, low-impact approach guarantees consistent quality while supporting local livelihoods and ocean resilience. Every batch is fully traceable from sea to product, aligning with FAO Blue Transformation Roadmap (2022) and UN Sustainable Development Goals principles for responsible production and marine stewardship.
Problem Solving Power
Seaweed harvesting offers far more than a natural raw material — it provides a practical, science-backed solution to several environmental pressures affecting marine and terrestrial ecosystems. Many coastal regions face nutrient overload, invasive seaweed blooms, and habitat degradation, challenges well documented in the FAO Global Seaweed Report (2018)and The State of the World’s Seaweeds (2025).
By responsibly managing and harvesting macroalgae, these excess nutrients are absorbed and converted into valuable biomass, helping to mitigate eutrophication and restore ecosystem balance, as highlighted in the FAO Pathways to Lower Emissions (2023) report.
This process turns an environmental challenge into a sustainable input, directly linking feed innovation with ecosystem regeneration and climate adaptation.
Antimicrobial Resistance
Antimicrobial resistance (AMR) is a growing global threat, with the Lancet - AMR Report (2024) warning that excessive antibiotic use in both human and animal sectors is driving rising mortality and diminishing treatment effectiveness worldwide. The report calls for urgent action to reduce antibiotic dependency through improved management, prevention, and sustainable practices in agriculture.
The World Bank Report "Drug-Resistant Infections: A Threat to Our Economic Future" (2017) estimates that unchecked AMR could cost the global economy up to $20 trillion in lost productivity. The report emphasises preventive strategies, including improved hygiene, biosecurity, and alternative health-supporting strategies in livestock production, as key to reducing antibiotic reliance and protecting future productivity.
By offering a natural, functional feed ingredient that support gut balance and overall resilience — OceanFeed™ aligns with industry efforts to reduce antibiotic dependence while maintaining animal performance and advancing sustainable livestock production.
Carbon Savings
Seaweeds are now recognised as powerful blue carbon ecosystems, capturing and storing substantial amounts of CO₂ as they grow. According to the World Bank Report "Global Seaweed - New and Emerging Markets" (2023)and the The State of the World’s Seaweeds (2025), macroalgae have one of the highest carbon-sequestration capacities among marine vegetation, while requiring no freshwater, fertilisers, or arable land. This makes seaweed farming a scalable, nature-based solution for reducing the environmental footprint of food and feed production.
Incorporating responsibly harvested seaweed into animal feed displaces more carbon-intensive ingredients and supports indirect emission reductions through improved feed efficiency and nutrient utilisation. These benefits align with the FAO "Pathways to Lower Emissions" (2023), which highlights marine ingredients as low-impact alternatives within the feed supply chain.
Through this approach, Ocean Harvest Technology helps partners integrate measurable carbon savings into their operations — offering a practical way to advance UN Sustainable Development Goals 13 while maintaining performance and sustainability in animal production.
Water & Land Use
Seaweed stands out as one of the few agricultural resources that requires no freshwater and no arable land, relying instead on marine nutrients, sunlight, and natural water movement. This unique growth pattern allows seaweed to thrive without competing with human food crops or freshwater supplies — two areas of growing global concern, as outlined in the FAO Global Seaweed Report (2018) and Wisser et al. (2024). Large-scale modelling studies (e.g., Nature, 2023) indicate that integrating seaweed into feed formulations could substantially reduce the land-use pressure associated with traditional feed ingredients, contributing to a more sustainable food system overall.
By using whole-seaweed biomass and avoiding water-intensive extraction or chemical processing, Ocean Harvest Technology ensures that production remains resource-efficient and low-impact. This natural efficiency helps mitigate deforestation, freshwater depletion, and land-use competition — all while providing feed manufacturers and integrators with a stable, climate-resilient raw material.
The result is an ingredient with high functional value and a significantly lighter environmental footprint, fully aligned with FAO Pathways to Lower Emissions (2023) and UN Sustainable Development Goals 12 and 14 for responsible production and marine stewardship.
Contributing to UN Sustainable Development Goals
Through our sustainable seaweed sourcing and production practices, Ocean Harvest Technology actively supports the following UN Sustainable Development Goals:
Social Responsibility & Circular Economy
Sustainability extends beyond environmental stewardship — it also encompasses social equity and circular resource use. Guided by the principles of the FAO Blue Transformation Roadmap (2022) framework and the UN Sustainable Development Goals (SDGs), Ocean Harvest Technology integrates ethical responsibility and regenerative economics into every stage of its supply chain. Certified under the SA8000 Social Accountability standard, we ensure that all operations adhere to fair labour practices, safe working environments, and human-rights compliance. Our partnerships with coastal communities emphasize training, fair compensation, and long-term collaboration, generating stable livelihoods and empowering local economies in regions where opportunities are often limited.
Aligned with circular economy principles highlighted in the World Bank Report "Global Seaweed - New and Emerging Markets" (2023), our production model transforms excess marine biomass — including overgrown or invasive species — into high-value feed ingredients. This approach closes the loop between ecosystem restoration and economic utility, turning environmental challenges into sustainable growth opportunities. By embedding transparency, traceability, and measurable social impact into our operations, Ocean Harvest Technology demonstrates that responsible sourcing and ethical production can coexist with profitability, setting a benchmark for a truly regenerative feed industry.
