A demonstration experiment has begun at Kushiro Port in Hokkaido in an attempt to utilize the carbon dioxide "blue carbon" absorbed by seaweed for new measures against global warming.

"Blue carbon" is carbon dioxide absorbed by seagrass through photosynthesis, and is expected to lead to global warming countermeasures by increasing seagrass beds in the same way as tree planting.

The Tokyo company "Japan Blue Carbon Project" started a demonstration experiment at a seaweed bed in Kushiro Port on the 9th to commercialize the initiative.



In the experiment, we decided to spend three years verifying the conditions for creating a high-quality seaweed bed where kelp grows easily, and on the 9th, a diver dives into the offshore seaweed bed and works to remove seaweed that hinders the growth of kelp. Was.

A study conducted by the Hokkaido Development Bureau at Kushiro Port found that the amount of carbon dioxide absorbed by seaweed beds is 0.53 kg per square meter per year, which is 2.4 times more effective than forests.



The company aims to regenerate seaweed beds all over the country in the future and sell the frame of absorbed carbon dioxide.



Mr. Takumi Kato, Managing Director, said, "We would like to contribute to the prevention of global warming while solving the problem of" rocky-shore "where seagrass beds disappear by making use of the regeneration technology obtained in the experiment."
