Quality & Sustainability

A high quality product and sustainability, in our eyes one does not come without the other. These two core business values guide us forward and help us produce the highest quality seaweeds, now and into the future.

It starts with a licence

We are fully licenced to harvest seaweed by the Crown Estate. The qualifying principle for a licence is sustainability and approval from Natural England.

Because we were among the first to start a seaweed business in England, there was a need to establish the Code of Conduct for Seaweed Harvesting, which Natural England established with our collaboration. The Code lays out harvesting guidelines to ensure harvesting is carried out without significantly impacting the ecosystem.

Code of Conduct examples of guidelines 

  • Seaweed can only be harvested by hand
  • Only a part of each individual plant can be cut, above the point of growth to allow regrowth
  • Other wildlife should not be disturbed
  • Harvest seaweeds during the active growth season to allow for quicker recovery
  • Rotate harvesting areas to allow ample time for recovery. Harvested areas should be left for up to several years, depending on the species, before harvesting again.

Where we do not harvest from Crown Waters, we make sure we have consent from the relevant land owners.

Soil Association Organic Qualification – Ensuring High Quality, Nutritious Products

We are proud licencees of the Soil Association. Organic status guarantees our products and the location they are harvested from are of high quality – seaweeds need to be harvested from areas of high ecological quality and meet Class A or B standards as defined in Annex II of Regulation (EC) No 854/2004.

In addition, the EU regulation on organic production (EC) No 834/2007 states that collection should not affect the long term stability of the natural habitat or the maintenance of the species in the collection area.

To top it off, the Soil Association prohibits use of chemicals and requires us to have a proper waste management in place.

Renewable Energy

Extracting water from seaweeds is an energy-intense process. Where most, if not all, seaweed companies in the UK and EU use dehumidifiers, ovens or electric heaters, we have perfected our drying process so that our seaweeds are mostly dried using direct solar and wind energy. Saves energy bills, saves the climate.

Seaweed Research

Ensuring seaweeds are harvested sustainably is a bit of a challenge. Very little research has been carried out on regrowth rates, biomass and optimum harvest quantities in the long-term. But one has to start somewhere.

Together with Exeter University we have developed a monitoring project that will look at our harvesting regime, harvest quantities and biomass changes over the years. This will inform us and regulating bodies to provide more specific harvest deadlines and provide quota that are based on scientific data rather than anecdotal evidence.

Using scientifically equipped drones as well as through ground studies we aim to increase our understanding of seaweed growth rates, biomass, distribution and harvest impact on different species.
