Seaweeds are increasingly recognized as sustainable food

January 2026 - December 2027

GROWIER develops land-based seaweed cultivation using the nutrient-rich saline process water remaining after magnesium extraction, enabling clean, consistent and year-round production.

In collaboration with Nedmag, Hortimare, Hanze University and TU Delft, the project builds a circular seaweed value chain in the Northern Netherlands.

April 2025 - May 2029

Healthy Algae develops nutritious and better-tasting algae ingredients through gentle, minimal processing and applied food testing. Together with Wageningen Food & Biobased Research and industry partners, the project explores algae applications in plant-based and hybrid foods, bakery products and fermented foods.

The aim is to make algae a trusted and appealing ingredient in everyday diets, supporting a more resilient and sustainable food system.

April 2025 - April 2026

Stikstof Spons explores whether seaweed grown on land can capture nitrogen from saline water streams, offering a nature-based approach to improving water quality.

In the context of the ongoing nitrogen crisis, the project aims to lay the foundation for a circular and scalable bioremediation system that supports healthier ecosystems.

January 2025 - November 2026

Early in 2025, Seaweedland along with Hortimare, received a  subsidy for developing knowledge on the optimal controlled, on-land cultivation of multiple Asparagopsis strains with high bromoform content for the purpose of methane emission reduction in cows. Integrating Asparagopsis as a supplement into cow feed, could reduce their methane gas emmissions significantly. 

March 2024 - February 2026

Seaweedland is currently conducting an MIT Technology R&D project with three partners, to cultivate seaweed in a land-based facility, using salt ground water. Methods of water analysis, water treatment and automatic control of water parameters for the optimal conditions for seaweed cultivation in on-land systems are being developed, allowing for potential use of subterranean salt water sources in the future.

March 2024 - February 2026

Seaweed is healthy, sustainable, and suitable for a variety of uses. Yet, seaweed is not widely used, especially in Europe. Supported by SNN, the Dutch Ministry of Economics and Climate, and the European Union, the SNN Valorization 2024 subsidy was  granted to Seaweedland and multiple other partners for valorizing seaweed and strengthening the supply chain in the Netherlands.

March 2024 - November 2026

Seaweedland is working alongside multiple partners in developing  seaweed cultivation systems in between two dikes in Bierum, where regenerative and nature inclusive farming and aquaculture with salt water is the focus.
