About Kelp blue

We harvest cultivated kelp to produce ingredients for agriculture, pharmaceuticals, and textiles.

To restore our planet to equilibrium, or even to abundance, we need to come together to find cost-effective, long term and environmentally sustainable solutions. At Kelp Blue, we believe we’ve found one such solution: growing and managing large-scale Giant Kelp forests.

The process

The Hatchery

The sorus tissue, the fertile material that is found on mature kelp blades, is taken to our hatchery. A safe and controlled environment where we nurture the kelp from near microscopic gametophytes, through to sporophytes - the multicellular leaf-like stage. Once big enough, the sporophytes are attached to a special wire and made ready to be planted in the ocean.

outplanting

At the out-planting stage, the twine is wrapped around our farm structures. Our farm uses lines and ropes onto which the holdfast - the root-like foot of the kelp - can securily attach. Our team of divers will secure the twine to the structures and regularly monitor the progress of the growing kelp.

Engineering

The farms are submerged in the ocean. In the deeper water we have installed structures that are anchored at around 15 metres below the surface – the perfect depth to maximise access to nutrients and light while keeping the young kelp out of the most violent movement of the waves.

marine monitoring

Our dedicated marine monitoring team regularly check on the kelp and keep track of the biodiversity observed. They use a range of different methods including methods like acoustics, visual observations, water sample analysis, and environmental DNA. We also regularly measure water quality and analyze dissolved organic carbon in the lab.

harvesting

Once the kelp grows to maturity and starts forming a canopy, some of the biomass is harvested to turn into sustainable alternatives for industries such as agriculture and packaging. Currently the kelp is harvested by hand, but we are working on a fully-automated solar powered emission-free  harvester which would allow us to significantly scale up our operations.

processing

Our kelp is carefully processed to extract its bioactive compounds. Through innovative techniques, we concentrate these compounds into potent biostimulants that increase crop yield, improve soil health, reduce chemical dependency, and improve abiotic stress stress tolerance.

quality control

Quality control is at the core of our operations. Every batch undergoes rigorous testing to ensure consistent performance, which is crucial for biostimulants to perform consistently in varying agricultural environments. Rigorous testing ensures that our products deliver reliable, optimal results, every time.

R&D

The R&D team valorizes all components of the kelp. Our new products include a bio-based leather alternative, as well as blended fabrics and coatings. We extract alginates and fucoidan, which can be used in cosmetics, nutraceuticals and as input materials for bio packaging or as gelling agents.

how we do it

Innovation is at the heart of what we do. It isn’t just about “tech”, innovation is actually very human— it takes heart, it takes soul; from everyone involved. Because big innovation has big impact on the planet and people.

Meet the team

We are so proud of our hard-working Kelpies, who work tirelessly to make our oceans a little better every day.

vision 2029

By 2029, our goal is to remove over 1 million tons of CO2 annually through 70,000 hectares of Giant Kelp farms located 30-100 km offshore from Lüderitz. These farms benefit from the Benguela Current, which is twice as productive as the Chile current and nine times more productive than the California current. This results in a 10%-20% increase in regional fish stocks and biodiversity, creating over 400 local jobs and indirectly supporting 800-1,000 more.
