Chemical Substance Management
Minimizing Chemical Substance Risks
The Dexerials Group has established chemical substance management regulations for the entire company and has organized a Chemical Substance Management Committee to ensure continued product compliance concerning chemical substances, to continue providing safe and secure products to our customers into the future, and to maintain the work environment, and is strengthening its systems for the appropriate, integrated management of the chemical substances used by the company.
As well as managing the use of chemical substances in the company’s business activities, the committee checks and deals with regulatory aspects of matters ranging from the purchase of raw materials to product design, manufacture, distribution, import and export, to ensure that the company responds appropriately to recent legislative amendments relating to chemical substances, both within Japan and overseas. This committee is a cross-functional organization comprising members selected from among each division, and while each member has the role of ensuring compliance for chemical substances in their respective posts, activities are also proactively expanded by the committee, including giving advice for company-wide activities using the specialist knowledge from their respective posts. The information shared among the committee is shared not only with Plants in Japan but also with overseas locations, so that the Group is managed as a whole, including confirming the status of overseas locations by the Secretariat. Also, in terms of sub-documents for chemical substance management regulations, by-laws have been established for the chemical substances management regulations that clarify the rules from introduction through to use, product shipping, and disposal.
Response to the Pollutant Release and Transfer Register (PRTR) Law
The Group ascertains the results of release and transfer volumes of chemical substances based on the PRTR Law, and reports the total amounts for each year. Chemical substance release and transfer volumes for each plant in the fiscal 2018 are shown below.
We use a method to divide data into release or transfer based upon the distribution coefficient* of actual purchase of chemical substances.
At Dexerials, adhesives and adhesive tapes using many organic solvents are produced, so the emissions volume of toluene, etc., is high as a result.
Regarding these organic solvents, the volatile gases emitted during the manufacture of adhesive tape are recovered, and re-used as energy by means of a heat exchange through combustion in a boiler.
- * Distribution coefficient: A method of calculating the value of corresponding changes in actual purchase values by setting a coefficient for movements/emission volumes inthe product manufacturing process.
FY 2019 PRTR Substances
|Plant||Chemical substance||Release/transfer volume calculation (t)|
|Kanuma Plant||Acrylic acid and its water soluble salts||0.173|
|Antimony and its compounds||0.164|
|Nakada Plant||Manganese and its compounds||0.097|
|Cobalt and its compounds||0.000|
Appropriate Import and Export Control of Chemical Substances
Imports and exports of chemical substances may require procedures such as notifications and registrations. The Dexerials Group responds to such regulatory requirements through local sales or manufacturing subsidiaries or consulting companies. The relevant laws of Japan include the Act on the Regulation of Manufacture and Evaluation of Chemical Substances and the Industrial Safety and Health Act and those of overseas jurisdictions include the REACH Regulation*1 of the European Union, K-REACH*2 of South Korea, TSCA*3 of the US, and the new regulatory frameworks for chemical substance management of China and Taiwan.
- *1 REACH: Abbreviation of Registration, Evaluation, Authorization and Restriction of Chemicals. The Reach Regulation was issued on June 1,2007.
- *2 K-REACH: Act on the Registration and Evaluation of Chemicals of South Korea
- *3 TSCA of the US: Toxic Substances Control Act of the US
Management of chemical substances introduced
Because the chemical substances have a risk of adverse effects on the environment and health, for all chemical substances introduced, we conduct risk evaluations and Dexerials proprietary classifications based on risk assessment methods in order to strengthen use management. Regarding classification standards, the risk impact is correctly determined using criteria such as laws and GHS categorization results*.
- * GHS Classification: “The Globally Harmonized System of Classification and Labelling of Chemicals” are classification standards adopted by the UN in July 2003 for dangerous and harmful chemicals.
Chemical Substance Management Education
The Dexerials Group frequently uses chemical substances in R&D and product manufacturing. For that reason, thorough education regarding the handling of chemical substances is given to employees from the time they join the company, and there is an internal curriculum that is implemented, including post-employment OJT and special education for specific materials. The company also recommends the acquisition of qualifications for handling materials, and all employees in the manufacturing and R&D Divisions have the necessary qualifications for handling hazardous materials.
Introduction of a Comprehensive Management System for Chemical Substances
The Dexerials Group has introduced a management system whereby raw materials and chemicals/reagents in wide use by development departments that are purchased are managed on a single system and recorded in a chemical substance database so that the data can then be output by item for PRTR totals and other objectives. This is useful for preventing compliance violations, as it can be widely used for investigations into the use of chemical substances by individual manufacturing departments, R&D Divisions, regulations or substance at plants in Japan and overseas, and to respond to revisions in applicable laws.
