  • Fulfill regulatory compliance for global markets

European Biodynamic Standards

European Biodynamic Standards

Seagreens® was Europe’s first organically certified ‘ocean-to-table’ seaweed producer. In 2004 Seagreens® were also approved to European Biodynamic Standards (the UK Biodynamic Agricultural Association) for use in Biodynamic and Organic foods and farming systems.

In 2007 Biodynamic approval was extended to the United States of America under Biodynamic® and NOP Organic Standards.

Biodynamic Agricultural Association: Registration Number 398


Certified Organic

Certified Organic

The Biodynamic standards are like an "organic plus" certification in that the standards are higher than regular organic standards.

Seagreens® are therefore fully certified organic by the UK Biodynamic Agricultural Association and Seagreens® Seagreens human food standards surpass EU 834/2007, 889/2008, 710/2009 regulations.


Certified Contaminant Free

Seagreens® are certified free of all likely ocean-borne contaminants, toxic metals and microbial pathogens by The Centre for Food Innovation at Sheffield Hallam University (Britain’s leading centre in food industry research and management) and by government accredited laboratories in England, Scotland, Norway and other countries.

This is your assurance that Seagreens® products are free of PCBs, organotins, organophosphates, aromatic hydrocarbons, toxic metal pollutants like arsenic, cadmium, lead, mercury and other toxic metals, and pathogenic bacteria like coliforms, e.coli, enterobacteria, moulds, rubella, staphylococcus aureus, salmonella and vibrio species.

Every harvested batch is independently tested for allergens, pollutants, contaminants, and key marker nutrients which upholds Seagreens unique standard of nutritional value and purity.


Certificate of Analysis

Seagreens® seaweed harvests regularly undergo scientific analyses to check for toxins and contaminants.

Most seaweed is allergenic because of the crustacea normally included. However as part of the Kosher certification process, Seagreens® is certified allergen free.

This is particularly important for special diets, mothers in pregnancy and children.
