A Novel Extraction Process for Seaweed

With Bio-activity and Sustainability at its Core



This is Seaweed have identified a process that will deliver a zero-pollution solution that is both low energy and low cost. Due to the non-abrasive nature of this process, the full suite of marine phenolics can be extracted and utilised.

A unique suite of nutraceuticals

Seaweed bioactives including polysaccharides, pigments, fatty acids, polyphenols and peptides have been proven to possess various beneficial biological properties that could potentially contribute to functional food and nutraceutical development.

A sustainable      plant-based protein

Seaweed protein is a source of all amino acids, especially glycine, alanine, arginine, proline, glutamic, and aspartic acids.

A fibre extract with multiple uses

Seaweed fibre is an excellent source of dietary fibre, and has been reported to impart similar improvements in human gastrointestinal health and other benefits to those obtained from dietary fibres in terrestrial plants.

Health promoting alginates

Alginate is currently found in some slimming aids, thickening agents for soups, jellies, ice-cream, cosmetics, drinks and pharmaceutical preparations.

Optimise and scale extraction technologies for proteins
and alginates from macroalage

This is Seaweed was founded by Marine Biologist Paul O'Connor in 2015 and is based at the NovaUCD Innovation and Research Campus in Dublin. The company operates in the Plant-Derived Nutraceutical sector. With the rapid growth in the Healthy-Eating and Plant-Based food sectors driving demand for functional food ingredients, This is Seaweed aims to position itself as the go-to producer of sustainable seaweed extracts that future-thinking companies will demand.


This is Seaweed is committed to technological innovation; both in the active ingredient extraction process, and the ultimate ingredient delivery format across a range of health areas.
We recently agreed on a collaborative technology development project with Teagasc, underpinned with funding from Science Foundation Ireland (SFI). The project is investigating the optimal technology configuration for extracting macromolecules - such as protein and carbohydrate - from seaweed.
