Making an Impact

Leveraging the benefits of seaweed to tackle some of the largest problems to society and the health of our planet.

Problems the World Faces

Food Security & Wastes from Fish-farming

Wastes from fish-farming

To meet the dietary needs of the 10 billion people who will be on the planet by 2050, significantly more protein will be needed. Currently more than 3 billion people get at least 20% of their animal protein from fish.

Aquaculture is a critical part of the solution. Yet the industry, despite widely acknowledged improvements in efficiency and technologies, faces limits to growth. Governments and local communities are resistant to expansion and new siting due to concerns about fish waste and related water pollution.

Co-located seaweed farming, sited and managed responsibly, has the potential to reduce nitrogen and phosphorus loading significantly in coastal waters.

A Mounting Climate Crisis

A mounting climate crisis

The Paris Climate Agreement, growing regulatory pressure and a surge in extreme weather events are increasing corporate urgency to reduce carbon emissions. Yet government investments in clean energy infrastructure lag behind corporate commitments to Net Zero, slowing progress. Many companies and investors are looking for other near-term opportunities to support carbon reductions and removals.

Geoengineering-based ‘carbon drawdown’ technologies like carbon capture and storage are not yet affordable or at commercial scale. Nature-based carbon removal solutions like seaweed are often lower-cost and more accessible.

Oceans Drowning in Plastics

The Oceans are Drowning in Plastics

Every day, plastic is flowing into our natural environment at an unprecedented rate – a dump truck worth every minute. Brand and manufacturers are under growing pressure to limit use of petroleum-based plastics in their products through reuse, recycling, and substitutes.

An expected UN Global Plastic Treaty – anticipated for 2024 – could ban high-risk plastic products and encourage reuse, recycling and bioplastic alternatives.

Seaweed can serve as a low-impact feedstock for making biodegradable plastics.

Habitat & Biodiversity Loss

Habitat & Biodiversity Loss

Human pressures are the driving factor for the decline of marine habitat and biodiversity loss in the world’s oceans. We are responsible for habitat alteration, overfishing, ocean acidification, pollution from agriculture and human caused debris. It’s time to give back to the ocean, the very system that supports life on Earth.

Responsibly reseeding the seabed with seaweed will enhance the health and resilience of marine ecosystems, restore biodiversity, and support marine life populations, effectively benefiting the environment and human society.

Why Seaweed?

Seaweed offers a versatile, nature-based solution for climate change mitigation and for counteracting the eutrophication and biodiversity crisis.

Seaweed soaks up excess nitrogen and phosphorus from fish waste - Integrated Multi-tropic Aquaculture (IMTA) methods can be applied, where seaweed is grown near fish farms and both systems will benefit from it.
By drawing CO2 out of the ocean waters - thereby allowing the oceans to absorb more CO2 from the atmosphere - seaweed helps fight climate change.
The amount of carbon captured can be directly measured.
Seaweeds can grow very fast – at rates more than 30x those of land-based plants - resulting in a high carbon capture rate.
We can regenerate marine habitat through spores from seaweed modules, creating a canopy for other marine life - Biodiversity can be enhanced by cultivating multiple species of seaweed in a single system.
Seaweed farming creates sustainable jobs in local communities.
Seaweed can be harvested to produce a range of products including food products, biochar, pharmaceuticals & alternatives to plastic packaging.
Seaweed grows naturally and does not require any pesticides or fertilisers.
Seaweed is of profound significance to First Nations People and other coastal communities worldwide. It is used for cultural activities, food, domestic uses, shelter, medicines, fishing and art & craft.
