Muddy soil that flows in from rivers coagulates as soon as it enters the ocean, depositing and damaging eelgrass beds, the cradle of young fish. Flocculants are used to purify the muddy water, but some of the conventional flocculants are harmful to living organisms. Therefore, we believe that we can contribute to the conservation and sustainable use of marine ecosystems (the SDGs 6 and 14) by developing flocculants made from natural materials that are safe for living organisms.
The United Nations has designated the decade starting in 2021 as the "Decade of Ocean Science," with the aim of contributing to the SDGs. Ocean science, as defined by the UN, includes the field of fisheries.
