Our approach

Sargassum (Phaeophyceae) is a brown seaweed that has spread massively. A floating mass of seaweed stretching from the Gulf of Mexico to West Africa is now the biggest seaweed bloom in the world. The vast rafts of it keep sunlight from reaching coral reefs; as it decays, the seaweed releases noxious compounds that harm marine life.

Sargassum is harvested from Caribbean beaches and coasts.

Fucus vesiculosus, also knowns as bladderwrack, is a seaweed that is good for our oceans. It absorbs carbon dioxide (CO₂) from the water in much the same way as land-based plants take it from the air. CO₂ makes seawater acidic, and excessive acidity can damage marine life. So Fucus vesiculosus naturally manages the acid content of the sea.

Fucus vesiculosus is harvested from the shores of the Baltic Sea. We are developing seaweed farming infrastructure for it.

Kelp (Laminariales) are large brown seaweeds that grow in underwater forests, which provide habitats for a variety of marine life. Kelp grows incredibly fast and removes more CO2 than land forests do. Overfishing and overharvesting have led to the degradation of kelp forests. Other major factors which threaten kelp include marine pollution and the quality of water, climate changes and certain invasive species.

Kelp is farmed globally, though it is relatively new in Europe. It can be grown relatively easily with existing infrastructure. Kelp surface canopy can be harvested with boats several times per year. This is possible due to fast growth while the vegetative and reproductive parts are left undamaged.

Blue-green algae aka cyanobacteria forms harmful algal blooms (HABs) in nutrient-rich waters. It has reached epidemic levels lately due to fertiliser and sewage runoffs and rising global temperatures. They produce a wide array of neurotoxins, liver toxins, cell toxins, and skin irritants.

We harvest blue-green algae from the Baltic Sea with a special harvesting vehicle.
