The Three Aspects of Kurita’s Environmental Improvement ActivitiesTechnological Innovation

Basic Approach

As for technological innovation, Kurita Water Industries Ltd. strives to contribute to creating a sustainable society by developing new products and technologies to respond to various environmental issues that are difficult to solve with existing technologies. New products and technologies developed in fiscal 2017 are discussed here.

DReeM Polymer TM Awarded the Environmental Technology Award for the 49th JCIA Technology Award

In May 2017, Kurita Water Industries’ multi-functional polymer material DReeM PolymerTM was awarded the Environmental Technology Award at the "49th JCIA Technology Award" sponsored by the Japan Chemical Industry Association (JCIA). DReeM PolymerTM is a revolutionary water treatment chemical material that not only has a dispersion effect that prevents deposits such as calcium, silica, etc., present in boiler water attaching to the interior of boilers as scales* but also removes scales that have accumulated. Using the chemical makes it possible to dramatically cut CO2 emissions due to reduced boiler fuel use because it not only maintains heat conductivity by removing scales but also makes it possible to reuse water condensed from boiler steam that contains scales as boiler water. The award was given because both the environmental benefit and contribution to advances in science and technology were highly praised.

  • *Scales : Deposits of materials such as calcium and silica contained in water on the interior of boilers. They dramatically reduce heat conduction and results in lower fuel efficiency and durability of the boiler.
