Seagriculture USA

7-8 September 2022

Portland, ME, USA


“With support of the state of Maine the organisers of the Seagriculture conference launch USA edition in 2022!”

The organisers of the Seagriculture Conference, DLG Benelux, are pleased to announce the launch of Seagriculture USA, the first international seaweed conference in North America. Seagriculture USA will take place from 7-8 September 2022 in Portland, Maine. 

Being the hotspot for the seaweed industry in North America the state of Maine is proudly supporting this first international seaweed conference in the USA. The conference is being supported by Maine Department of Economic and Community Development (DECD), Maine Technology Institute (MTI), Maine International Trade Center (MITC) and Maine North Atlantic Development Office (MENADO). 

The Seagriculture conference has built up a solid reputation as the leading conference for the Seaweed industry, Seagriculture has been successfully organised since 2012. The USA edition comes in addition to the European conference which takes place every year in another country in Europe. By expanding Seagriculture to the USA the organisers aim to create synergy between both events as well as to contribute to knowledge exchange

between Europe and North America and foster a dialogue for the rapidly growing seaweed industry. The choice to host the first edition of Seagriculture USA in Portland, Maine, is a natural one. The state of Maine has been at the forefront of the developing seaweed industry in the USA and the state is actively supporting the industry. In 2018, the total haul of farmed seaweed in Maine was around 54,000 pounds, then grew to 280,000 pounds in 2019. A projection from the Island Institute suggests that the annual take could top more than 3 million pounds by 2035.

Also, internationally the seaweed industry is booming, according to Fortune Business Insights the global commercial seaweed size is projected to reach USD 23.04 billion by 2027 (USD 13.33 billion in 2019), exhibiting a CAGR of 5,8% during the forecast period. By adding Seagriculture USA to the portfolio the organizers want to make a positive impact on the seaweed industry and community and make the connection between Europe and
North America enabling industry professionals to learn from one another.

The European edition of Seagriculture will next year be organised in June in order to accommodate the USA edition in September. The organisers of Seagriculture are proud to work with the different state organisations from the state of Maine and strongly believe that both events will strengthen one another creating a dedicated platform for the entire industry.

On 15 & 16 September the tenth edition of Seagriculture took place in an online format. Although that the tenth edition took place online the organizers have worked very hard to arrange a great lineup of speakers and added new features such as the Seaweed Quiz, European Union – Seagriculture Algae Innovation Awards and a special USA night session focusing on seaweed activities in the USA.

More than 25 speakers from 11 countries worldwide shared their knowledge, expertise and above all passion for all aspects of seaweed farming. Not only the speakers focused on the technical aspects of seaweed farming but also aspects such as ecosystems, marketing, supply chain, sustainability and future developments were addressed.

With over 180 registrations this edition of Seagriculture was the best-attended event so far. This clearly shows that the seaweed community is growing and that seaweed professionals are interested in a platform such as Seagriculture to share knowledge and connect with other professionals in the industry. In addition to the high number of registrations, it was remarkable that the attendees were coming from all over the globe, overcoming different time zones. In total Seagriculture welcomed participants from 27 countries.

On 16th September, Felix Leinemann, Head of Unit Blue Economy Sectors, Aquaculture and Maritime Spatial Planning, European Commission, DG Maritime Affairs and Fisheries handed out the European Union – Seagriculture Algae Innovation Award to: Green Technology Research Institute, CPC Corporation, from Taiwan - Gold, THE BLUE FUTURE from Spain - Silver and Rhodomaxx SDN BHD from Malaysia – Bronze and audience award.

In total 16 innovations were submitted from all over the globe of which 40% were submitted from Europe, this underlines the innovative character of the seaweed industry.

Transitioning to a sustainable blue economy requires investing in innovative technologies. Whether this is in wave or tidal energy, algae production, development of innovative fishing gear or restoration of marine ecosystems, the objective is to create new green jobs and businesses in the blue economy.

By funding the Seagriculture Innovation Awards the European Commission shows its commitment to transitioning to a sustainable blue economy and offers entrepreneurs and academia the possibility to contribute to this transformation by highlighting their innovative services and products which could make a positive impact on our blue economy.

During the USA night session, Dana Eidsness, director of the MENADO at Maine International Trade Center introduced Seagriculture USA 2022, which will be held on 7-8 September in Portland Maine.

Maine is one of the hotspots for seaweed farming in the USA so the choice for Portland, Maine, comes as a natural one. Seagriculture USA is being sponsored by: Maine Department of Economic and Community Development (DECD), Maine Technology Institute (MTI), Maine International Trade Center (MITC) and Maine North Atlantic Development Office (MENADO).

The USA edition comes in addition to the European edition of Seagriculture which will next year be held in Bremerhaven, Germany and which is being supported by Bremerhavener Gesellschaft für Investitionsförderung und Stadtentwicklung mbH.
