CSR InitiativesProduct Quality Improvement

Provide Highly Safe Services and Products

The Kurita Group recognizes that continuing its business and growing as a company depends on maintaining its status as a trusted supplier for its customers. To gain the trust of our customers, we believe we must consider the impact on customers of the actual products that we supply, which is to say, we must develop products and services that consider safety, health, and environmental impact throughout the product lifecycle, and also ensure their stable manufacture as well as safe shipment and delivery.

The Kurita Group will strive to maintain the trust of society by continuing to develop and provide products and services that are considerate of safety, health, and the environment.

Product Quality Improvement Initiatives

The Kurita Group has established the “Kurita Group Product Quality Policy” and continuously promotes quality improvement activities based on this policy in an effort to raise the quality of the products and services it provides to customers.
The basis of this policy is the “Kurita Group will speedily provide our customers with products and services that can meet their quality expectations, thereby winning unshakable trust.” To provide products and services that are trusted by customers and to fulfill our social responsibilities in conducting our business, we have established the policy with the goal of conducting quality activities that take into account observance of laws and regulations, safety and quality, and environmental impact. To improve quality, each Group company has built and operates a quality management system based on the policy. In addition, we constantly monitor the current quality level through self-inspections, surveys by the person in charge of promoting quality improvement activities or their designated person, and feedback of opinions and requirements from customers. Improvements are to be made each time an issue is recognized.

Basic Policy

  • We will establish a quality management system suitable for the business environment and continue improvement activities to enhance customer satisfaction.
  • We will actively disclose appropriate information concerning products and services and provide safe and secure products and services.
  • We will determine quality control processes and criteria, properly operate them, regularly confirm the operation status and thereby secure the quality of products and services.
  • We will promote the development and improvement of products and services considering environmental impact and contribute to environmental preservation.

The Company has a rule that, when it uses a new chemical substance in product development, it assesses the risk the chemical substance poses to the environment and health based on internal rules. In addition, when we manufacture a product, we submit mandatory notifications and reports following laws and regulations, including the Industrial Safety and Health Act, the Act on the Evaluation of Chemical Substances and Regulation of Their Manufacture, etc., and the Fire Service Act.
In addition, to ensure the appropriate provision of information to customers, we use GHS*1-compliant SDS*2 and labels to inform them of applicable laws and hazards of the product and provide other information. We also issue Yellow Cards*3 and affix Container*4 Yellow Cards to ensure transportation safety.

  • ※1 GHS stands for the Globally Harmonized System of Classification and Labeling of Chemicals. Under this system, physical hazards and health hazards/environmental hazards of chemicals are classified based on international standards, and products classified as hazardous ones are stated on SDSs and indicated on the containers. GHS has been introduced in many countries in accordance with a recommendation by the United Nations. In Japan, compliance with GHS is required by the Industrial Safety and Health Act.
  • ※2SDS(Safety Data Sheet), is a sheet on which a product’s hazards, applicable laws, how to handle and transport the product, emergency measures, and other information are presented in a specific format. The Company creates SDSs for all of its products, commodities, and developed articles and provides them to its customers.
  • ※3A Yellow Card is a yellow-colored card showing information about procedures for handling an accident as a safety measure for transportation of a chemical. This card is prepared by the transport operator and taken along when a chemical is transported on a tanker truck or the similar vehicle.
  • ※4A Yellow Card cannot be used in the case of consolidated transport or transport of small lot products. Therefore, in such a case, the Company affixes a label indicating safety information (United Nations Number and Emergency Response Guide Number of the chemical name) on each container.

Promotion System

The Company has built systems for quality management covering all stages from development to manufacture and supply of products and services, and is working to improve quality.
For research and development, the Solutions Business Committee screens the development themes of high performance chemicals, units, and solution technologies and the specific details of the decided themes are set by the Research and Development Division and the Solution Business Division. For quality management for the stages from manufacture to provision of products, the Quality Management Committee is established within the Engineering Division to oversee the quality improvement activities of each organization. The Company has also created systems for autonomously carrying out continuous quality improvements and maintains quality management systems.

Initiatives in Fiscal 2018

Conducting CS Survey

Products that Contribute to “Safety Improvement”and “Response to Legal Changes”

The Kurita Group strives to provide customers with highly safe products and services. We are working to develop products and services where the products themselves feature improved safety and response to legal changes, based on laws, regulations, and standards related to safety and the environment in each country, as well as moves towards future regulations. Here we present some examples.

CETAMINETM Water Treatment Chemical for Boilers Offers Outstanding Safety

Boilers that generate steam are widely used for electricity generation and production processes in plants, as well as air conditioning in office buildings, hospitals, and other facilities. To curb the amount of fuel and feed water used in boilers and achieve efficient operation, water treatment chemicals for boilers are generally used. Hydrazine has long been used as a boiler water treatment chemical, but requires caution when handling due to recent concerns that it may be carcinogenic.

The CETAMINETM product produced by the Kurita Group was developed by Kurita Europe GmbH. It is a highly safe water treatment chemical that does not contain Hydrazine.Traditionally, treatment of boiler water required the use of three types of agents: a boiler compound, an oxygen scavenger, and a pH adjuster. However, CETAMINETM effectively integrates all of these functions into a single compound, enabling customers who manage boilers to reduce their handling of chemicals.

The Kurita Group will continue to offer the CETAMINETM series not only to respond to the hydrazine issue, but also to comply with environmental laws and regulations in each country and region.

Kurita’s Absorbent Contributes to Lithium-Ion Battery Safety Improvement and Service Life Extension

Left: A new battery
Right: A battery after repeated charging and discharging

Lithium-ion batteries are widely used in electronic devices such as mobile phones and PCs. With their increasing use in electric vehicles, household appliances, and other areas, the batteries are advancing with higher output power and capacity. Repeated charging and discharging of lithium-ion batteries causes CO2 to be generated inside them. This creates an increase in pressure within the sealed batteries that brings a risk of swelling, bursting, or catching on fire.

Kurita Group manufactures a special absorbent that absorbs the generated CO2 gas, making lithium-ion batteries safer. Moreover, since the product also absorbs metal ions emitted from the electrodes during discharge, it suppresses adherence of the ions to the electrode and film formation, thereby extending the service life of the battery.
