What Seaweedland does
Seaweedland is a Dutch private company (legally Iceventures B.V.) founded in 2022 and headquartered in Leeuwarden, Netherlands, that operates controlled on-land seaweed cultivation facilities across multiple Dutch sites including Heerhugowaard, Veendam, Groningen, and Amsterdam. The company's core technology is a proprietary land-based cultivation platform using engineered tanks and raceway systems with filtered subterranean salt water, automated CO2 supply, optimized artificial lighting, and mechanical harvesting, enabling year-round production without reliance on ocean conditions, freshwater, or wild harvest contamination risks. Seaweedland produces four seaweed species — Ulva (sea lettuce), Palmaria palmata (Dulse), Gracilaria, and Asparagopsis — targeting food service, food manufacturing (notably hybrid meat products), cosmetics, dietary supplements, livestock feed (methane reduction via Asparagopsis), and aquarium markets.
The company monetizes through three primary streams: direct seaweed product sales via the Rungis distribution channel to Dutch restaurants and chefs; ingredient supply to food manufacturers such as Seaweed Food Solutions and Royal Smilde; and a planned global franchise and licensing model that packages its cultivation platform for international partners. Strategic differentiation rests on being co-located within Hortimare (the world's leading seaweed seed breeding specialist), government-validated R&D with over EUR 980,000 in cumulative Dutch and EU grants, and circular-economy partnerships such as the GROWIER project with Nedmag that converts saline industrial process water into cultivation feedstock. The company has won industry recognition including three gold medals at Slavakto 2024 for hybrid meat sausages incorporating its seaweed, and was nominated for the Change Inc Transition Awards 2026.
