Blue Symbiosis – Australia

We are researching converting oil and gas infrastructure into multi-species regenerative seaweed aquaculture sites to establish foundational and reproductive habitat, sequester carbon, mitigate eutrophication, and provide seaweed for bioplastics, nutrition and sustainable construction materials.

Repurposing oil and gas infrastructure as a stepping stone to rapidly scale seaweed production. We have a vision to create a symbiotic relationship between humanity and our oceans.
