Using kelp to accelerate the shift to sustainability

The incredible potential of kelp as an Environmentally friendly input material is ready to be unlocked



Kelp Blue Biotech is providing a viable long-term solution to various industries that historically rely on unsustainable inputs or extractive practices that leave a negative environmental impact by using the natural compounds found in cultivated kelp, especially giant kelp.

We strive to make a positive environmental impact on the agricultural and pharmaceutical industries by introducing a natural and ethical input material.

We exist to accelerate the shift to sustainability in multiple industries by using cultivated kelp.

We achieve this by employing a biorefinery, or zero waste model, where we use processing methods that use every component of the of the harvested material.


Kelp’s unique composition allows it to be used for a variety of products:
  • it is an extremely effective crop biostimulant (allowing farmers to drastically reduce the use of chemical fertilizers),
  • it’s a fantastic input material for the plastic replacement industry. Alginates, which are only found in brown seaweed, are the cornerstone input for biodegradable films and packaging
  • the fucoidans and fucoxanthins with their anti-oxidant and anti-cancerous properties make them an effective ingredient for the pharmaceutical, nutraceutical and cosmecuitcal industry.,
  • the lipids, proteins, sugars and the overall effect of the seaweed on animal gut health make  it a perfect animal feed supplement.  
While we’re able to process all types of kelp, Kelp Blue Biotech is currently only focused on processing cultivated Macrocystis Pyrifera, or giant kelp, the largest seaweed species on the planet.  
Macrocystis is often seen as “the new kid on the block” as it’s a comparatively understudied and under-researched species. We have a  team of knowledgeable and very curious scientists who are fully dedicated to unlocking the (untapped) potential of giant kelp. Our aim is to  create a full range of products with properties superior to those already on the market. 



The existing kelp value chain is fragmented and inefficient at responding to fluctuations in supply and quality. Plus it’s generally not sustainable since much of the kelp used in leading products is harvested from wild kelp beds and forests.

Kelp Blue Biotech sources seaweed from our sister company Kelp Blue in Namibia. This allows us to have a fully integrated supply chain, from R&D, harvesting, processing to market development and sales, all with a guaranteed sustainable and steady supply.

While Kelp Blue Biotech is responsible for the processing, research and product improvements as well as sales and marketing, our sister company Kelp Blue Namibia ensures we have access to a large-scale steady supply of sustainably cultivated macrocystis– 120,000 tonnes of it per year.


We expect to harvest  120 tonnes per hectare (per year) of giant kelp to be turned into:
