Utilizing sea urchin shells to regenerate seaweed beds in isoyake areas

As part of our commitment to sustainability, we also promote the use of sea urchin shells, which would otherwise become industrial waste.

Sea urchin shells, which are expensive to dispose of, are mixed with natural rubber and sunk into the sea as compost blocks, where they are planted with seaweed seeds such as kelp.

This compost block manufacturing and seaweed bed restoration initiative is being developed in the town of Shakotan town, Hokkaido.

This initiative is currently undergoing a demonstration experiment.
