How is Seaweed Sustainable?

The true potential of a thing usually depends more on its application than its own inherent qualities.

Algae (and seaweed) may in many ways be regarded as the lungs of the sea – in continuation of this, they may even be simultaneously seen as the liver or kidneys of it. If cultivated in an ethical manner, seaweed is probably one of the most sustainable crops we have access to.

This is especially true when we look at sustainability in the cross-section of various areas (environmentally, socially and governmentally). In addition to all of this, it is also very tasty and useful in various ways.

As seaweed is an overall easy, nutrient rich and sustainable crop to grow, it can play a pivotal role in combating the malnutrition and hunger that we see around the world today. It is also a protein-rich alternative to the CO2 heavy meat, that many of us in the western world are looking to substitute.

It even contains the essential omega 3 fatty acids that we cannot make on our own - as well as some of the renowned non-digestible fibers working as prebiotics.

There are also strong indications that the use of seaweed for animal feed can help us avoid overly use of antibiotics – thereby combating antibiotic resistance.

Moreover, several preliminary studies have found that seaweed contains compounds that boost the immune system. This is another aspect of seaweed we are working on in Pure Algae - in close collaboration with Hanse Garnelen in Germany - as we aim to establish a regenerative cycle for seaweed that mimics its role in the natural ecosystem.

This in short means that we use the nutrient rich water left from the aquaculture of aquatic livestock to fertilize the seaweed in our system, which in turn is fed to the livestock - making them bigger and healthier. In other words, seaweed is full of health benefits to both humans and animals alike.

At Pure Algae we recognize the need for the integration of multiple solutions to address the challenges facing the marine environment, as each comes with its own advantages and limitations – But we are clear in our conviction that seaweed is an important player in this area – whether it is grown on land or at sea.
