Diasalt Research Laboratory: Broader horizons and stronger value for seawater

Seawater is the source of life. Embracing seawater from multiple perspectives, we research and develop ways to give shape to its boundless possibilities. The Laboratory does more than simply develop new products; it also works closely and firmly with production sites, working to take quality and technology to the next level.

01.Comprehensive technologies that take full advantage of seawater components

Using our array of proprietary technologies, we transform raw materials of all kinds into the high value-added products that the market needs. Our ability to achieve ideal specifications through advanced refining and blending technologies, without being bound by raw-material restrictions, is the essence of our identity as a company.

02.Treating product design as material development and turning the results into difference-makers

We position ourselves as a company that creates new value, not just as a salt manufacturer.
We continuously improve functionality and develop applications to meet needs in food, the medical field, the industrial sphere, and more. One key feature of our research and development is our ability to quickly, efficiently integrate everything from laboratory testing to plant design and mass production.

03.Site-based research to solve problems on the front lines of production

Theoretical research is not where we stop. Our efforts turn into real outcomes. We emphasize the idea that research should be closely linked to the places where production actually happens and directly related to process efficiency and quality improvement.
Our site-centric approach—a belief that what comes out of our laboratory should enhance our production capacity—helps us ensure a stable supply and improve the quality of our products on a day-to-day basis.

04.Cultivating trust through high-precision analysis and a rigorous evaluation system

To meet the demanding safety requirements of the medical and food fields, we ground our operations in precision analytical technology.
That means exercising meticulous control over ingredients and performing quality assurance based on detailed analysis of product data. We support the creation of reliable products on a solid foundation of scientific evidence.

05.Fostering a recycling-oriented society and aiming for zero emissions

An important focus for our research is the effective use of by-products like bittern, which comes out of the salt-manufacturing process, as valuable chemical products.
All in all, we are dedicated to minimizing our environmental footprint by utilizing ocean resources as fully as possible. Holding true to our recycling-oriented research philosophy, we will continue to develop technologies that contribute to a sustainable society.
