Management of Chemical Substances
Management of Chemical Substances
Many ink raw materials are chemical substances, and to ensure "the safety of our production workers" and "the safety of our printing company customers when using our products," we have designated "substances that we will not use as raw materials" and "substances we will use with appropriate management", and have established a management structure based on the respective risks and hazard assessments (classified into management levels 1 - 4).
We are a member of the Japan Printing Ink Makers Association, which has compiled a Negative List (NL) Regulations (voluntary restrictions related to printing ink). The NL Regulations selects substances that are not desirable as raw materials for printing ink from the viewpoints of human safety, health, and environmental impact, and prohibits their use, and our manufacturing complies with this regulations.
We have also introduced a chemical substance management system for comprehensive management of chemical substances used throughout the company, to resolve issues such as responding appropriately to the latest legal and regulatory revisions, obtaining the latest hazard information, and compliance with regulations on chemical substances implemented by EU and countries in Asia.
In addition, "the Chemical Substance Management Committee" meets quarterly, or when revisions are made to a national regulations or to the Negative List Regulations. The Committee is chaired by the General Manager of the Technical Division with participation by members from the technical, logistics, sales, production and administrative departments, and works to improve and strengthen our initiatives for our use and management of chemical substances while referencing regulations on chemical substances such as those in Europe and the United States.
Submission of Safety Data Sheets
The Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof (the "PRTR Law"), the Industrial Safety and Health Act, and the Poisonous and Deleterious Substances Control Act all require the submissions of Safety Data Sheets (SDS) listing information related to the properties and condition and handling of chemical substances when products containing covered chemical substances are sold.
We create databases of chemical substances using SDS, certificates of non-use, and composition information received from suppliers to centrally manage the SDS for products we manufacture, which are then provided to customers by the sales departments.
Curtailing Emissions of Substances Covered by the PRTR Law
Many of the substances covered by the PRTR Law that are emitted into the atmosphere as part of our manufacturing processes are solvents used to clean tanks and other equipment. We therefore switched from using cleaning solutions containing volatile organic compounds (VOC) to non-VOC cleaning solutions from fiscal year 2009, and have taken other measures to replace substances with ones that have less effect on the human body and the environment. The Saitama Factory has reduced its annual emissions of PRTR substances and class 2 organic solvents from 41 tons in fiscal year 2009 to 3.0 tons in fiscal year 2019.
Yearly emissions of PRTR substances and class 2 organic solvents (for amounts handled exceeding 1 ton / year)
|Atmospheric Emissions (ton)|
|Fiscal year 2017||Fiscal year 2018|
|Cumene||Less than 0.01||0.01|
|Ethylbenzene||Less than 0.01||Less than 0.01|
|Formaldehyde||Less than 0.01||Less than 0.01|
|Acrylic acid||Less than 0.01||Less than 0.01|
|Phenol||Less than 0.01||0|
|Piperazine||Less than 0.01||0|
|Total class 2 organic solvents*||2.70||2.46|
- *Class 2 organic solvents excluding toluene and other PRTR substances
We appropriately store 1,285 kilograms of high-concentration polychlorinated biphenyl (PCB) products that are used in transformers and condensers. We have conducted appropriate disposal by an outside vendor in June 2020.
