Despite all this, Europe still produces only a tiny fraction of the world’s seaweed: 90% of the estimatedSteinhagen inspects the tanks in her “seaweed kindergarten”.
One way to find more sea access is The Seaweed Company’s experiment in growing seaweed between offshore wind turbines in the North Sea. Meanwhile, some companies are developing their own seaweed harvesting machinery to make the job less labour intensive. But there’s still no seaweed equivalent of a combine harvester or tractor you can buy off the shelf.
This is only half of the puzzle. In the city of Gothenburg, a team at Chalmers University of Technology is looking at how to most efficiently and economically extract the protein.
