Using kelp to accelerate the shift to sustainability

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

Our mission is clear: we want to help others achieve the United Nations’ sustainable development goals with substantial numbers. The potential positive impact of kelp on our environment and industries is enormous.  Giant kelp not only acts as a replacement material, but in many cases,  has superior benefits over other materials.

The Kelp Blue Biotech difference

We have guaranteed access to a large  scale steady supply of sustainably cultivated macrocystis– 120,000 tonnes of it per year. Cultivation is carried out by our sister company in Lüderitz, Namibia where macrocystis  is grown in the clean, clear nutrient rich waters of the Benguela current.

How does macrocystis differ from other kelps?

Macrocystis has a different  chemical composition to other kelps like Ascophyllum and Ecklonia making it perfect as an effective biostimulant, a fantastic input material for plastic replacements as well as a sustainable agri-feed. Its high fucoidan and polyphenol content make it an effective pharmaceutical-grade ingredient.

Macrocystis is often referred to as “the new kid on the block” as it’s an understudied and researched species. For us, this is an advantage, because there are so many more applications for giant kelp just waiting to be uncovered.

We’re dedicated to advancing the knowledge around giant kelp and it’s applications and have various projects underway with universities and research institutions to uncover the miraculous molecules found in giant kelp—starting with its ability to halt cancerous rover cells from invading healthy tissue.
